SAFETY INFORMATION

FCC EXPOSURE LIMITS

This mobile radio transceiver was tested by the manufacturer with

an appropriate antenna in order to verify compliance with Maximum Per-

missible Exposure (MPE) limits set under Section 2.1091 of the FCC

Rules and Regulations. The guidelines used in the evaluation are derived

from Table 1 (B) titled “Limits For General Population/Uncontrolled

Exposure” which is from FCC report OET bulletin #65.

SAFETY INFORMATION

Table 2 lists the antenna whips and bases recommended for use in

each frequency range. Each model of this radio was tested with the appro-

priate antenna listed. The antenna was mounted in the center of the roof

of a domestically manufactured 4-door passenger sedan. The radio manu-

facturer has determined that the user and service personnel should remain

one (1) meter in distance away from the antenna when transmitting. By

maintaining this distance, these individuals are not exposed to radio

frequency energy or magnetic fields in excess of the guidelines set forth

in Table 1.

NOTE: If the installer or user changes the type or location of the

antenna, they should be aware of the MPE guidelines shown in

Table 1 and take measures to comply with those guidelines.

GENERAL OPERATION

Power-Up Sequence

When power is turned on, the backlight turns on, all segments in the

display are momentarily enabled, and the last seven digits of the trans-

ceiver part number are very briefly displayed. A beep then sounds (if

tones are enabled) and the transceiver is ready to be used.

Determining Volume Level

The relative volume setting can be determined by noting the position

of the index on the volume knob. You may also be able to enable a refer-

ence tone or background noise for use in setting the volume. Proceed as

follows:

• If key press tones are enabled, a short tone sounds when an option

switch is pressed or the Select switch is pressed or rotated.

GENERAL OPERATION

• If a conventional system is selected, take the microphone off-hook and

if someone is using the channel, voice is heard. If no one is using the

channel, the squelch control can be adjusted counterclockwise as

described in “Setting Squelch Control” on page 18 and noise is heard.

It is not possible to unsquelch the transceiver in this manner when a

Multi-Net or LTR system is selected.

Backlight Operation

The display and keypad backlight can be controlled by the BACK-

LIGHT menu parameter (see page 40). The three states that can be

selected are Bright, Dim, and Off. If this menu parameter is not select-

able, the backlight is fixed in one of these states by programming.

System/Group Display Information

The selected system and group are displayed using either a Numeric

or Alpha Tag display mode. The display mode is selectable if the S/G

DISPL menu parameter is available (see page 33). Otherwise, it is fixed

in one of these modes by programming.

Numeric Mode - In the numeric mode, the selected system and group

numbers are displayed on the top line as Sxx and Gxx, and the group

alpha tag is displayed on the bottom line. For example, System 1, Group

1 (CAR 220) is displayed as follows. The system alpha tag is not

displayed in this mode.

Select Mode Indication With Alpha Tag Display

The transceiver can be programmed so that after a change is made,

the current select mode remains enabled or a default mode is selected

after a delay of up to 15 seconds. This programming also controls the

mode that is selected when power is turned on.

Setting Squelch Control

NOTE: This sets the squelch level used for conventional calls. The

squelch level for Multi-Net and LTR calls is preset and not affected by

this adjustment. For more information on the various operating modes,

refer to page 40.

If conventional systems are programmed, the squelch level can be

set if the FCN option switch is enabled. Proceed as follows:

1. Select a conventional system and then a group that is not busy. Take the

microphone off-hook to enable monitoring.

2. Press the FCN switch and then rotate the Select switch as you would a

normal squelch control. Rotate it counterclockwise until receiver noise

is heard and then clockwise slightly past the point where the noise

mutes. The squelch adjust mode is indicated by “SQUELCH” on the

upper line of the display, and the relative squelch level is indicated by

a bar graph on the bottom line.

3. To select the current level and exit this mode, press the Select switch.

This also occurs automatically 2 seconds after no change is made or 8

seconds after no activity.

STANDARD CALLS

4. If both narrow and wide band channels are used, perform this adjust-

ment on both types because separate settings are maintained.

NOTE: Some readjustment may be required if weak messages are not

heard or unsquelching occurs when no messages are present.

STANDARD CALLS

Introduction

Most calls you make are probably the standard type described in this

section. These calls are between you and another mobile or control

station. The main difference between these calls and the other type that

can be placed (special calls) is that no number is dialed using a keypad.

The following procedure applies to all three types of operation (Multi-

Net, LTR, and conventional).

Placing a Standard Call

1. Turn transceiver power on and set the volume as described starting on

page 15. With conventional operation, also set the squelch as described

on page 18.

2. Select the system and group of the mobile being called as described in

“Selecting the System and Group” on page 17.

3. If a conventional call is being placed, monitor the channel manually or

automatically as described on page 42.

4. Press (and hold) the microphone PTT (push-to-talk) switch to talk and

release it to listen. Operation with Multi-Net, LTR, and conventional

systems is as follows:

Multi-Net and LTR Operation

• If the proceed tone is enabled (see page 30), it sounds shortly after

the PTT switch is pressed to indicate that the radio system was

STANDARD CALLS

successfully accessed. If it is not enabled, no tone sounds when the

system is successfully accessed. The proceed and other tones can be

disabled as described in “Tone Select” on page 32.

• If the radio system is busy, the busy tone sounds (see page 54) and

“BUSY” is indicated on the lower line of the display. If you continue

pressing the PTT switch, the system is accessed when it becomes

available. With Multi-Net operation, if Busy Queuing is

programmed, the call is automatically placed in a queue when the

PTT switch is released (see page 43).

• If an out-of-range condition exists, the intercept tone sounds (see

page 54) and “OUT-RNGE” is indicated on the lower line of the

display. No more access attempts are made once this indication

appears. Release the PTT switch and drive closer to the radio system

or away from shielding structures and try again. With Multi-Net

operation, if Roaming is programmed (see page 44), the transceiver

automatically changes sites before an out-of-range condition occurs.

Conventional Operation

• If the channel is busy and the Transmit Disable On Busy feature is

programmed, “DSBL BSY” is indicated on the lower line of the

display, the busy tone sounds, and the transmitter is disabled (see

page 51).

• Otherwise, busy and out-of-range conditions are not indicated and

speaking can begin when the PTT switch is pressed after monitoring

the channel. If the proceed tone is enabled on conventional systems,

it indicates when speaking can begin but does not indicate that the

radio system has been successfully accessed.

5. When the call is complete, place the microphone back on-hook.

Receiving a Standard Call

1. Turn transceiver power on and set the volume as described starting on

page 15. With conventional operation, also set the squelch as described

on page 18.

TELEPHONE CALLS AND OTHER SPECIAL CALLS

2. Select or scan the system and group programmed for the call you want

to receive (see page 35 for scan information).

3. When the message is received, the display usually changes to the

system and group of the call. Take the microphone off-hook and press

the PTT switch to talk and release it to listen. If scanning, a response

may not automatically occur on the group of the call (see page 39).

TELEPHONE CALLS AND

OTHER SPECIAL CALLS

Placing Telephone Calls

NOTE: Telephone calls can be placed and received only if that service is

available to you and your transceiver has been programmed appropri-

ately. A microphone equipped with a telephone keypad is required to dial

the telephone number.

The telephone calling feature allows you to place and receive tele-

phone calls using your transceiver. The following information describes

how these calls are made with Multi-Net and LTR operation. If you can

make telephone calls with conventional operation, the procedure may be

somewhat different and your system operator will then provide additional

information. Proceed as follows:

1. Turn transceiver power on and set the volume as described starting on

page 15.

2. Select the system and group programmed for telephone calls. When a

telephone or Multi-Net special call group is selected,

is displayed.

3. To obtain the dial tone, briefly press the PTT switch. If the proceed tone

is used, press the PTT switch until a beep sounds. If a dial tone is then

heard, proceed to step 4.

TELEPHONE CALLS AND OTHER SPECIAL CALLS

Busy and Out-Of-Range Conditions

Busy and out-of-range conditions are indicated the same as with

Multi-Net and LTR standard calls described on page 19. The

following additional features may be available with telephone calls:

Busy - With LTR operation, if Busy Queuing is programmed (see

page 48), the call is automatically placed in a queue when the PTT

switch is released. The Busy Queuing mode is indicated by “IN

QUEUE” in the display.

Out-of-Range - With LTR operation, if the System Search feature is

selected (see page 49), that feature is automatically selected when the

PTT switch is released. The System Search mode is indicated by “SYS

SRCH” in the display.

4. With the dial tone sounding, dial the number using the 0-9 keys on the

microphone keypad. If the microphone has a memory, you may also be

able to recall the number from memory. The PTT switch does not need

to be pressed while you are dialing if the transmitter automatically

keys. If too much time elapses between digits, the call is terminated.

5. After the number is dialed, release the PTT switch (if it was pressed).

With Multi-Net operation, a short tone then sounds to indicate that the

number was accepted by the system. Landside ringing (or a landside

busy condition) should then be heard.

6. When the other party answers, press the PTT switch and respond. The

PTT switch must be pressed to talk and released to listen (the same as

with mobile-to-mobile calls).

7. When the call is finished, it should be terminated. This is usually done

by pressing the # key, and termination is indicated by three beeps.

Terminating the call in this manner prevents extra billing that may

occur while the system automatically detects the end of the call.

TELEPHONE CALLS AND OTHER SPECIAL CALLS

Receiving a Telephone Call

1. Turn transceiver power on and set the volume as described starting on

page 15.

2. Select or scan the system and group programmed for telephone calls.

When a telephone or Multi-Net special call group is selected,

displayed.

3. When “ringing” is heard, press the PTT switch and respond. The PTT

switch must be pressed to talk and released to listen the same as with

standard calls.

4. When the call is finished, it should be terminated as in step 7 of the

preceding section.

Placing Other Multi-Net Special Calls

Multi-Net special calls include the telephone calls just described and

also Unique ID and Directed Group calls. Unique ID calls are to specific

mobiles, and Directed Group calls are to specific groups. These calls can

be placed to other users assigned to your site or some other site that is

part of the same network.

As with telephone calls, a microphone with a telephone keypad is

required to dial the number specifying the mobile being called. The

numbers dialed are 4-8 digits long, and they will be provided by your

system operator. The procedure used to place these calls is as follows:

1. Select the system and group programmed for Unique ID and Directed

Group calls. When one of these groups or a telephone group is selected,

is displayed.The group alpha tag displayed on the lower line may

also indicate when one of these groups is selected.

2. Briefly press the PTT switch to obtain a dial tone. The procedure is

similar to that used with telephone calls, and the Busy Queuing and

Roaming features are available if programmed. Refer to step 4 near the

bottom of page 19 for more information.

TELEPHONE CALLS AND OTHER SPECIAL CALLS

3. Dial the 4-8 digit number using the microphone keypad. Refer to step

4 on page 22 for more information.

4. A tone then sounds to indicate that the call was accepted by the system.

If this tone does not sound, an incorrect or unauthorized number may

have been dialed. The call then proceeds as follows:

Unique ID Call - Ringing is heard to indicate that the other transceiver

is being rung. If there is no answer, ringing automatically stops after

several rings and the call is terminated. When the other party answers,

respond as with a standard call.

Directed Group Call - A second tone sounds to indicate that the path

is complete and you should transmit your message. No ringing occurs

and the other party does not answer first.

5. When the call is finished, it should be terminated by pressing the # key.

Three beeps indicate that the call has been terminated.

Receiving Other Multi-Net Special Calls

When a Unique ID call is received, a ringing tone sounds similar to

when a telephone call is received. Unique ID calls are received regardless

of which group is selected. All that is required is that a system

programmed for that call must be selected. To respond to a unique ID

call, you may need to manually select the unique ID group if it is not

selected automatically or some other group is displayed when the PTT

switch is pressed.

To receive and respond to a Directed Group call, the group

programmed with the ID code being sent must be selected. This call is

handled the same as the standard call described on page 20. No ringing

occurs, and an incoming call is indicated when you hear the voice of the

person placing the call.

GENERAL FEATURES

Landside-Originate Calls

Calls can be placed from a landside telephone to your transceiver if

the radio system and transceiver have that capability. With most systems,

a mobile can be called directly (each has a unique telephone number).

With others, a mobile may be called as follows:

1. Dial the number of the radio system in which the mobile is operating.

2. When the system answers, a short tone sounds to indicate that the

number of the mobile should be dialed. This is a 4-8 digit number that

is supplied by your system operator, and it must be dialed using a tone-

type telephone. If too much time elapses before dialing is started or

between dialed digits, the call is terminated.

3. If it is a telephone call, ringing is heard by the landside caller while the

mobile is being rung. With other calls, a second tone sounds instead of

the ringing tone and the landside caller should then begin talking.

GENERAL FEATURES

Bank Select

A bank is a collection of selectable systems that have been set up for

a specific application. For example, one bank could be programmed for

operation in Minneapolis and another for operation in Milwaukee. Each

bank is identified by a unique alpha tag, and up to sixteen banks can be

programmed.

Banks are selected by the BANK SEL menu parameter (see

page 33). Rotate the Select switch to display “BANK SEL” on the top

line and the current bank is then displayed on the bottom line. Press the

Select switch to change the bank. If this menu parameter is not available,

banks are not selectable.

GENERAL FEATURES

Call Indicator

The call indicator is “C” in the upper part of the display as shown in

the following illustration. The purpose of this indication is to show that a

call was received while you were away from the vehicle. Individual

groups can be programmed for this feature and it then turns on when a

call is received on one of those groups.

Call

Indicator

This indicator is turned off by pressing any button or turning trans-

ceiver power off and then on. If scanning and the “last received” configu-

ration is programmed (see “Transmitting In The Scan Mode” on

page 39), the system and group of the last call are displayed. Otherwise,

the currently selected system/group is displayed.

Emergency Switch

If the EMER option switch is programmed (see page 32), it is used

to set up or place a high priority call. When this switch is pressed,

“EMERGNCY” is displayed on the lower line (unless this message has

been disabled by programming).

With Multi-Net systems, either automatic or manual operation can

be programmed; with LTR and conventional systems, only manual opera-

tion can be programmed. Operation in these modes is as follows. Your

system operator may provide more information on how this switch should

be used.

Manual Operation - A specific system/group is automatically selected and

the transceiver goes into a high-priority access mode. However, no call is

placed until the PTT switch is manually pressed. This access mode mini-

mizes, as much as possible, the chance that the system will be busy when

the call is placed.

GENERAL FEATURES

Automatic Operation - The transmitter automatically transmits an emer-

gency message on the emergency system/group. The message is trans-

mitted without pressing the PTT switch and at the highest priority.

Emergency transmissions continue until an acknowledgment is received

from the dispatcher.

Encryption

Voice encryption is an optional feature that prevents conversations

from being monitored by casual eavesdropping and analog scanners. It

does this by encrypting your voice so that it can be understood only by

someone using a transceiver equipped with similar encryption device.

Each group can be programmed so that when it is selected, encryp-

tion is automatically enabled. When encryption is enabled,

cated in the display as shown below.

is indi-

Encryption

Indicator

If you have the ENCRYPT menu parameter or ENCPT option

switch, the encryption group programming can be temporarily over-

ridden. Selecting another system or group causes encryption to revert to

the status programmed for that group.

Encrypted calls are received even if encryption is not enabled.

However, encryption must be enabled to transmit an encrypted call.

When transmitting an encrypted call, wait approximately 1 second before

speaking. This gives the receiving encryption device time to establish

synchronization which ensures that all of the first word is received. If the

proceed tone is used (see page 30), speaking can begin as soon as it

sounds because it is delayed for the required time.

GENERAL FEATURES

Function (FCN) Switch

If an option switch is programmed for FCN (function), it performs

the following functions. If this switch is not programmed, these functions

are not available. When the function select mode is active, “FCN” is

displayed on the lower line of the display. The function mode is automati-

cally exited after 8 seconds of no activity.

Menu Mode Select - Pressing FCN twice selects the menu mode as

described on page 33.

Home System/Group Select - Pressing FCN and then the Select switch

selects the home system/group as described in the next section.

Squelch Adjust - Pressing FCN and then rotating the Select switch with a

conventional system selected sets the squelch level as described on

page 18.

Home System/Group Select

To select the preprogrammed Home system/group, simply press the

FCN switch and then the Select switch. The Home system/group is then

displayed and it becomes the selected system/group. If no home group

has been programmed, the last selected group of the home system is

selected. If you do not have a FCN switch, or no Home system is

programmed, this feature is not available.

Horn Alert

If this feature has been installed by your system operator, it activates

an external alert such as the vehicle horn or lights when a call is received

on a group programmed for horn alert. When the horn alert is enabled,

is displayed as shown in the following illustration.

Horn Alert

Enabled

GENERAL FEATURES

When enabled, the horn alert pulses on and off for 1-8 cycles and

then goes back to the disabled state. To change the currently selected horn

alert mode, the HORN option switch or HRN ALRT menu parameter can

be used if available (see page 32).

The horn alert is programmed to operate in the manual or automatic

mode (see descriptions which follow). If the ignition switch does not

control transceiver power, only the front panel power switch affects oper-

ation when applicable. Refer to “Power Turn-Off Delay” on page 30 for

more information.

Manual Off/On Mode

The horn alert mode does not change when power is turned on and

off by either the ignition switch or power switch. Therefore, the horn alert

is entirely controlled by either the HORN option switch or menu

parameter.

Auto Off/On Mode

Ignition Switch - The horn alert always turns off when the ignition switch

is turned on, and always turns on when the ignition switch is turned off (if

there is a turn-off delay).

Power Switch - The horn alert always reverts to the off condition when

power is turned on by the power switch.

NOTE: The preceding automatic operation overrides any mode that may

have been selected by the HORN option switch or HRN ALRT menu

parameter.

Option Select

The AUX switch or OPTION menu parameter can be used to control

an accessory that may have been installed by your system operator. If the

switch is used, the enabled condition is indicated by

in the display.

GENERAL FEATURES

Power Turn-Off Delay

Your transceiver may have been installed so that the vehicle ignition

switch as well as the front-panel power switch control transceiver power.

If this is the case, both the ignition switch and the front panel power

switch must be on for transceiver power to turn on.

When the ignition switch controls power, turn-off delays of Imme-

diate, 10, 20, 30, 40, or 50 minutes, 1, 2, 4, 8, 10, 12, or 16 hours or

Forever can be programmed. The delay can be overridden at any time by

turning power off using the front-panel power switch or turning the igni-

tion switch back on.

A power turn-off delay allows features such as the horn alert and call

indicator to remain active for a time after the ignition switch is turned off.

At the same time, advantages of ignition switch control are utilized such

as preventing battery discharge that may occur if the transceiver is acci-

dentally left on for an extended period (see page 62).

Proceed (Clear-To-Talk) Tone

This is a short tone that sounds shortly after the PTT switch is

pressed to indicate that the radio system has been accessed and speaking

can begin. This tone can be programmed so that it sounds on Multi-Net

and LTR systems but not conventional systems. In addition, this and other

tones can be disabled on all systems by the TONES menu parameter (see

“Tone Select” on page 32) or system operator programming, and either a

standard or loud (two-pitch) tone can be programmed.

On Multi-Net and LTR systems, if the radio system is busy when

making a call, the busy tone sounds instead of the proceed tone and

“BUSY” is indicated on the bottom line of the display. If the PTT switch

is held down, the system is accessed and the proceed tone sounds when it

is no longer busy. If an out-of-range condition occurs, the intercept tone

sounds and “OUT-RNGE” is indicated in the display. The PTT switch

must be released to make another call attempt. Refer to page 54 for more

information on the busy and intercept tones.

GENERAL FEATURES

On conventional systems, the Transmit Disable On Busy feature can

be used to automatically perform monitoring (see page 51). The proceed

tone then does not sound if the channel is busy. Otherwise, the proceed

tone (if enabled) sounds on conventional systems even if the channel is

busy.

With all operating modes, if encryption is used, a 0.9-second delay

occurs before this tone sounds and two beeps are heard instead of one. A

short delay may also occur with conventional calls. These delays ensure

that the radio path is complete before you begin talking so that part of

your first word is not lost.

Stealth Mode

The stealth mode disables the following tones and indicators so that

they do not reveal that you are transmitting or otherwise indicate your

presence. The speaker audio and display remain enabled in this mode.

• All tones (see “Tone Select” on page 32)

• The front panel transmit/busy indicator (see page 16)

• Display backlight

The stealth mode can be selected by an option switch or the

STEALTH menu parameter (see page 33), or is fixed in the on or off

mode by programming. There is no special indication that this mode is

selected except “On” is displayed under “STEALTH” in the menu mode.

Time-Out Timer

The time-out timer disables the transmitter if it is keyed continu-

ously for longer than the programmed time. It can be programmed for

0.5 - 5.0 minutes or disabled entirely. If the transmitter is keyed continu-

ously for longer than the programmed time, the transmitter is disabled,

“TIMEOUT” is indicated on the lower line of the display, and the inter-

cept tone sounds. The timer and tone are reset by releasing the PTT

switch. Ten seconds before time-out occurs, a beep sounds to indicate that

time-out is approaching. There is also a timer that can be programmed to

prevent transmitting for up to one minute after time-out occurs.

OPTION SWITCHES AND MENU MODE

One use of the time-out timer feature is to prevent a repeater from

being kept busy for an extended period by an accidentally keyed trans-

mitter. It can also prevent possible damage to the transmitter caused by

transmitting for an excessively long period.

Tone Select

If the TONES menu parameter is selectable, the tones that sound can

be selected. Otherwise, the tones that sound are fixed by programming.

The following choices are available. Refer to page 33 for more informa-

tion on using the menu mode.

Silent - All tones are disabled.

Key Beep - Only the Select switch and key press tones are enabled.

Alert - All tones except the preceding Key Beep tones are enabled.

All Tones - Both the Key Beep and Alert tones are enabled.

Transmitter Thermal Foldback

If the transmitter temperature increases to the point where damage to

the transceiver could result, power is automatically cut back. When this

happens, the transmit indicator on the front panel is orange instead of red

when the transmitter is keyed. After sufficient cooling occurs, power

output returns to the normal level and the indicator changes back to red.

One time when this indication could occur is if you transmit for an

extended period.

OPTION SWITCHES AND MENU

MODE

Option Switches

All five option switches on the front panel are programmable by

your system operator. The available option switch and menu mode func-

tions are shown in the table on page 34. Those which can be assigned to

an option switch are indicated by an entry in the “Option Switch”

OPTION SWITCHES AND MENU MODE

column. Refer to the page listed in this table for a description of the func-

tion. If a function is controlled by an option switch, it cannot be

controlled by the menu mode and vice versa. Some switches may not be

used and are then disabled.

Menu Mode Introduction

The menu mode is selected by pressing the FCN switch twice. If this

switch is not programmed, the menu mode is not available. Functions

which can be controlled by the menu mode are indicated by an entry in

the “Menu Items” column of the table on page 34. Refer to the page listed

in the table for a description of the function. Some functions may not be

used, may be in a fixed state, or may be controlled by an option switch.

The menu parameter that controls that function is then not displayed.

Using Menu Mode

To use the menu mode, proceed as follows:

1. To select the menu mode, press FCN FCN (the FCN switch twice). The

menu display is shown below. The top line indicates the function being

edited, and the bottom line indicates the current status of that function

SYSTEM AND GROUP SCAN

Introduction

The scan feature monitors, in sequence, the programmed systems

and/or groups in the scan list. When a message is detected that the trans-

ceiver is programmed to receive, scanning stops and the message is

received. Shortly after the message is complete, scanning resumes (unless

it has been disabled).

System Scanning - System scanning detects calls on all systems that are

in the system scan list. When system scanning is not used, calls are

detected on only the currently selected system.

Group Scanning - Group scanning detects calls on all selectable groups in

the current or scanned systems that are in the group scan list. When group

scanning is not used, calls are detected on only the currently selected

group or if system scanning, on the last selected group of each system.

System and/or group scanning are turned on and off by the SCAN

option switch. When system and/or group scanning is enabled by this

switch,

is indicated in the display (see following illustration). Then

when system or group scanning is actually occurring, a scrolling under-

line is displayed under each character in the upper line of the display. The

microphone must be on-hook for scanning to occur (unless off-hook

detection has been disabled by programming).

SYSTEM AND GROUP SCAN

System Scan List

Group Scan List

System or Group

Scanning Occurring

Scanning Selected

The type of scanning selected is determined by the menu mode SCN

TYPE parameter (see page 33). If that parameter is not selectable, the

type of scanning is fixed by programming. The available scan types are as

follows. Single and multiple site scan may also be selectable (see

page 37).

SYS-GRP - Both system and group

GRP ONLY - Group scanning only

OFF - Both types disabled (SCAN switch non-functional)

If the SCAN option switch is not programmed, the selected mode is

always enabled. If the switch is enabled but the menu SCN TYPE param-

eter is not selectable, the scan type is fixed by programming.

Group scanning can be selectively disabled on systems by program-

ming. It then does not occur on those systems even if enabled as just

described. The selected system and group can be changed while scanning

using the Select switch in the normal manner. Scanning resumes shortly

after the change is made.

When a call is received in the scan mode, the display changes to the

system and group of the call. Programming determines if this change is

temporary (until scanning resumes) or permanent, and if a response

occurs on the system/group of the call or the selected system/group. Refer

to “Transmitting In The Scan Mode” on page 39 for more information.

SYSTEM AND GROUP SCAN

Single and Multiple Site Scan

Single and Multiple site scanning (see descriptions which follow)

are selectable if the SCAN SEL menu parameter if it is available. If this

parameter is not available, scanning is fixed in one of these states by

programming. If you can select this parameter, your system operator may

provide more information on which type to use.

Single Site Scan - This type scans only Multi-Net systems that access the

site of the current system, and it usually must be selected with a Multi-Net

system displayed. If an LTR or conventional system is displayed and it

cannot be selected, an error tone sounds and “NOT MULTI” is displayed.

Multiple Site Scan - This type scans all systems in the scan list, and it must

be used to scan LTR and conventional systems.

Scan List Programming

General

NOTE: The selected (displayed) system and group are always scanned,

even if they are deleted from the scan list.

The system and group scan lists are programmed using the A/D

(add/delete) option switch. Pressing this switch changes the status of the

displayed system or group. The displayed system is in the scan list and

scanned normally when

is displayed. Likewise, the displayed group is

in the scan list and scanned normally when

preceding illustration).

is displayed (see

The system/group select mode described on page 17 also controls if

the system or group scan list is changed when the A/D switch is pressed.

For example, to change the scan list status of the displayed system, press

the Select switch if necessary so that the system select mode is indicated

and then press the A/D switch.

Deleting a system only temporarily deletes the groups associated

with that system. When a system is added back into the scan list, the orig-

SYSTEM AND GROUP SCAN

inal group scan list is again active. Systems and groups can be deleted

from the scan list while listening to a message on the system or group by

pressing the A/D switch in the normal manner. Scanning resumes shortly

after the system or group is deleted.

Scan list programming is not available if the A/D switch is disabled.

In addition, the group scan list is not programmable if the group scanning

is disabled on the current system. If an attempt is made to program the

group scan list on one of these systems, a beep sounds, “GSCN DIS” is

flashed in the display, and no change occurs in the scan list.

Saving Scan List

If the menu mode SCN SAVE parameter is available, you can select

if scan list changes are saved. If “On” is selected, changes are saved as

they are made and the scan list is the same when power is turned on. If

“Off” is selected, they are no longer saved. Therefore, to store a list,

select “On”, program the list, then select “Off”. Then when power is

turned on, the scan list returns to the state that existed when “Off” was

selected.

If the menu SCN SAVE parameter is not selectable, the scan list save

mode is fixed by programming. If “On” is programmed, all changes are

saved and no change occurs in the scan lists when power is cycled. If

“Off” is programmed, they are not saved and the scan list reverts to the

default status when power is cycled.

Scan Delay and Continue Timers

When a message is received or transmitted while scanning, there is a

short delay before scanning resumes. The delay after receiving a call

prevents another message from being received before a response can be

made. Likewise, the delay after transmitting a call ensures that you hear a

response to your call instead of another message occurring on some other

system or group. Note that scanning does not resume if it has been

disabled, such as by taking the microphone off-hook.

SYSTEM AND GROUP SCAN

There is also a scan continue timer that may be programmed. This

timer controls the maximum time that a call is received before scanning

resumes. Times up to 60 seconds can be programmed. This prevents

scanning from being delayed for long periods by lengthy calls. If the

menu SCN CONT parameter is selectable (see page 33), this feature can

be turned on and off.

Transmitting In The Scan Mode

General

When a message is received in the scan mode, programming deter-

mines if the selected system/group does not change or changes perma-

nently or temporarily to that of the call. This then affects the system/

group on which a response to the message occurs and also the system/

group that is selected when the scan mode is exited by pressing the

SCAN switch. The three programmable configurations are as follows:

Last Selected - Transmissions always occur on the system/group that

was last selected by the Select switch. Therefore, the display may not

indicate the system/group on which a response will occur. To respond to a

call not on the selected system/group, one of the following methods can

be used:

• Select the system/group of the call manually using the Select switch.

• Before scanning resumes, exit the scan mode by pressing the SCAN

switch. The system/group of the call then becomes the selected system/

group and it is not necessary to change it manually.

Last Received - The selected system/group changes to the system/group

of a call. Therefore, you can always respond to a call without having to

manually change the system/group. To return to the previously selected

system/group, manually select it using the Select switch.

Temporary Last Received - The system/group changes to the system/

group of a call for only the duration of the scan delay period (see

page 38.) Then when the delay expires and scanning resumes (if it is not

MULTI-NET, LTR, AND CONVENTIONAL MODES

disabled), the selected system/group is again displayed. Therefore, you

can respond to a call without changing the selected system/group as long

as you do so before scanning resumes.

Fixed System/Group Transmit in Scan

Each bank can be programmed so that transmissions in the scan

mode that are made while scanning is occurring are on a preprogrammed

system/group. Note that scanning must be occurring (scrolling underline

displayed) when the transmitter is keyed. Since taking the microphone

off-hook normally disables scanning (unless off-hook detection is

disabled), the transmitter usually must be keyed with the microphone on-

hook.

If a transmission occurs under these conditions, the selected system/

group also changes. If the transmitter is keyed with scanning halted, the

programming described in the preceding section takes precedence.

MULTI-NET, LTR, AND

CONVENTIONAL MODES

General

Each selectable system can be programmed for Multi-Net, LTR, or

conventional operation by your system operator. The type or types of

operation that are programmed in your transceiver are determined by the

type of radio equipment being used in your radio system. The differences

in operation are described in the following information and elsewhere in

this manual as required.

Multi-Net and LTR Operation

The Multi-Net mode provides the most operating features. Features

available only in the Multi-Net mode include roaming (auto-registration),

status messages, and special calls. The two types of calls that can be

placed with Multi-Net operation are Standard and Special. Special calls

MULTI-NET, LTR, AND CONVENTIONAL MODES

include telephone, unique ID, and directed group. Multi-Net features are

described starting on page 43.

LTR operation is similar to Multi-Net operation. The main differ-

ence is that the preceding features are not available. The two types of

calls that can be placed with LTR operation are Standard and Telephone.

LTR features are described starting on page 48.

Both the Multi-Net and LTR modes provide automatic channel

selection (trunking) and monitoring before transmitting. In addition,

special tones and display messages indicate busy and out-of-range condi-

tions. Selecting a system selects a collection of groups and other informa-

tion such as fixed priority receive ID codes. Selecting a group selects a

transmit and receive ID code and other information which controls the

mobile or mobiles being called and what calls are received.

Conventional Operation

In the conventional mode, selecting a system selects a collection of

channels and other information unique to those channels. Selecting a

group selects the specific channel and also squelch coding (if any) used

on that channel. Conventional features are described starting on page 50.

There are no tones or messages to indicate busy or out-of-range

conditions in this mode. A busy channel (group) is detected manually or

automatically as described in the following information. An out-of-range

condition cannot be detected automatically but may exist if you cannot

get a response to any of your messages. Refer to “Operation At Extended

Range” on page 61 for more information.

To properly receive calls in the conventional mode, the squelch

control must be set as described in page 18. If this control is not set prop-

erly, weak messages could be missed or noise could be heard when no

message is present. In the Multi-Net and LTR modes, the squelch level is

fixed and setting this control has no affect.

MULTI-NET, LTR, AND CONVENTIONAL MODES

Monitoring Conventional Channels Before Transmitting

Regulations require that the channel be monitored before transmit-

ting to make sure that it is not being used by someone else. If you were to

transmit when someone else is talking, you would probably disrupt their

conversation. As previously stated, monitoring is performed automati-

cally in the Multi-Net and LTR modes. In the conventional mode, it must

be performed automatically or manually as follows.

Automatic Channel Monitoring

If the selected group is programmed for the Transmit Disable On

Busy feature, monitoring is performed automatically. Refer to page 51 for

more information on this feature.

Manual Channel Monitoring

If the Transmit Disable On Busy feature is not used, monitoring

must be performed manually as follows:

Busy Indicator - With scanning disabled and the squelch control

adjusted as described on page 18, note if the indicator on the front panel

is green. If it is, a signal has been detected on the selected system

(channel) and you should not transmit a message until it turns off.

Monitor Mode - There may be times when the busy indication is on even

though no one is using the channel. Monitoring should then be performed

using the monitor mode. This mode is enabled by taking the microphone

off-hook (unless off-hook detection has been disabled by programming).

The monitor mode temporarily disables Call Guard squelch (see descrip-

tion on page 52) and scanning so that all messages on the channel are

heard. The monitor mode is indicated by

in the display as shown in the

following illustration. The monitor mode can also be enabled by the MON

or CG option switch if it is programmed. Refer to the monitor mode

description on page 50 for more information.

MULTI-NET FEATURES

MULTI-NET FEATURES

Standard and Special Calls

Standard calls are between two mobiles or between a mobile and a

control station, and special calls include telephone, unique ID, and

directed group. Standard calls are described starting on page 19, tele-

phone calls starting on page 21, and unique ID and directed group calls

starting on page 23.

Busy Queuing (Multi-Net)

The Multi-Net Busy Queuing feature places the call in a queue if a

busy condition occurs when the PTT switch is pressed. Then when the

radio system is no longer busy, a tone sounds and the call can be placed if

desired. This feature is enabled on individual Multi-Net systems by

dealer programming, and it is then available with all types of calls on that

system. This feature operates as follows:

If a busy condition exists, the busy tone sounds and the Busy

Queuing mode is entered automatically when the PTT switch is released.

The busy tone then stops sounding and “IN QUEUE” is displayed as

shown in the following illustration. When the transceiver successfully

accesses the system, either a beep or dial tone sounds. The beep sounds

MULTI-NET FEATURES

with all calls except telephone, and the dial tone sounds with telephone

calls. The call can then be placed in the normal manner.

When in the queue mode, calls are received normally. A response

can be made to a call and Busy Queuing resumes shortly after the call is

finished (if it was not on the selected group). If group scanning is

enabled, it continues. However, system scanning is temporarily disabled,

so calls are not received on other systems.

If a call is not placed soon after this tone sounds, the queue mode is

automatically exited and normal operation resumes. The queue mode is

also exited if any of the following occur:

• Pressing the PTT switch (except when responding to a call as

described above)

• A call is received on the selected group

• Pressing any front panel switch

• Turning power off and then on

Roaming (Auto-Registration)

Several Multi-Net sites can be linked together to provide wide-area

coverage. Mobiles can then roam from site to site and the radio system

tracks their location and calls are automatically routed to the correct site.

Telephone and unique ID calls are always routed to other sites, and stan-

dard calls may be routed.

To utilize the Roaming feature, all of the following requirements

must be met:

• The scan mode must be selected by the SCAN switch.

• The transceiver must be programmed for Roaming and it must be

available in your radio system.

• If the menu mode “ROAMING” function is available, “On” must be

selected.

Roaming functions as follows: When you move out of range of the

current site, the transceiver begins searching for the sites programmed in

MULTI-NET FEATURES

other selectable systems. While searching is occurring, “ROAMING” is

indicated on the lower line of the display as shown below. When a new

site is located, this message is no longer displayed, and the system and

group of the new site is displayed.

The new system is the first higher system with a different site that

could be accessed (wrap-around occurs after the highest system is

accessed). The new group is either the same group that was displayed

before roaming occurred or the last selected group of that system

(programming determines which is selected).

Transmitting Status Messages

Preprogrammed status messages can be transmitted whenever the

transmitter is keyed with a Multi-Net system selected. If this feature is

available, the STATUS menu parameter (see page 33) is programmed to

allow the desired message to be selected.

Selecting the STATUS menu parameter enables the status message

select mode. This mode is indicated by “STATUS” on the top line of the

display and the bottom line indicates the currently selected status

message (see following illustration).

Status Select Mode

Selected Status

Message

To change the current message, press the Select switch. When “NO

STAT” is selected, no message is transmitted. To select the current

MULTI-NET FEATURES

message and exit this mode, press the FCN option switch again. This also

occurs automatically 2 seconds after a change is made or 8 seconds after

no changes are made.

Up to eight status conditions such as “AT SITE”, “LEAVING”, and

“LOADING” may be preprogrammed by your system operator. The

selected status condition along with the unique ID of your transceiver is

then displayed on the dispatcher’s console whenever the transmitter is

keyed.

Caller Identification

The caller identification feature displays the four-digit unique ID of

the calling mobile. It is displayed on the bottom line as “UI XXXX”

alternately with the group alpha tag.

This feature can be turned on and off by the CALL ID menu param-

eter (see page 33). If this menu parameter is not available, the caller ID

feature is fixed in the on or off mode by programming. This feature is

also programmed on individual groups by your system operator. If it is

disabled on a group, the unique ID code is not displayed even if this

feature is enabled.

Calls on Priority and Block ID Codes

Two fixed priority and a block of receive ID codes can be

programmed. These codes are in addition to the receive and transmit ID

code selected by the group select function. Calls on the fixed priority and

block ID codes are received regardless of which group is selected or

group scanning. All that is required is that the system programmed with

those codes be selected or scanned.

Calls on the fixed priority ID codes have a higher priority than calls

being received on other ID codes. If a call with a higher priority is

detected while receiving a call, the current call is immediately dropped

and the higher priority call received. Telephone calls are not interrupted

by priority calls.

MULTI-NET FEATURES

If a call is received on one of the fixed priority ID codes, either

“PRIORTY1” or “PRIORTY2” is displayed on the bottom line. The

selectable groups are then checked to see if any have the same ID code. If

a match is found, the transceiver changes to that group. If no match is

found, the group does not change and a response cannot be made on that

ID code. The “Transmitting in the Scan Mode” programming described

on page 39 determines if a change is temporary or permanent.

When block ID codes are used, calls are detected on entire blocks of

ID codes. When a call is received on a block ID code, “BLK CALL” is

displayed and the selected group does not change.

Transmit Inhibit

The Transmit Inhibit feature prevents the transmitter from keying if

the mobile you are calling is busy with another call. When the transmitter

is disabled by this feature, the intercept tone sounds and “TX INHIB” is

displayed (see following illustration). To make another call attempt, the

PTT switch must be released and pressed again. However, you may

want to wait a few seconds before making another attempt so that the

other call can finish.

One use of this feature is to prevent the accidental interruption of a

call in progress. This could happen when the other party unkeys or if a

higher priority ID is transmitted. It may also be used to provide an indica-

tion that the mobile you are calling is busy with another call. A similar

Transmit Disable On Busy feature is available on conventional systems

(see page 51).

LTR FEATURES

Standard and Telephone Calls

Standard calls are between two mobiles or between a mobile and a

control station. Telephone calls allow you to place and receive calls over

the public telephone system using your transceiver. Standard calls are

described starting on page 19, and telephone calls are described starting

on page 21.

Busy Queuing (LTR)

The LTR busy queuing feature places a telephone call in a queue if

the radio system is busy when it is placed. Then when the system

becomes available, the call is automatically placed. Standard (mobile-to-

mobile) calls are not queued by this feature. If queuing is programmed

and a busy condition is encountered, the queue mode is entered automati-

cally when the PTT switch is released. The queue mode is indicated by

“IN QUEUE” on the bottom line of the display as shown below.

When the radio system becomes available, it is automatically

accessed. A beep then sounds and a dial tone is heard. The call can then

be placed if desired. The queue mode is exited before the call is placed if

any of the following occur (exit is indicated when “IN QUEUE” is no

longer displayed).

• The PTT switch is pressed

• Any call is received

• Any front panel option switch is pressed

• Power is turned off

Calls are received normally in the queue mode. However, receiving

any call causes the mode to be exited as indicated above. Group scanning

LTR FEATURES

remains enabled while in the queue mode, but system scanning is tempo-

rarily disabled. This feature is enabled on individual LTR systems by

dealer programming, and it is then available with all telephone calls on

that system.

System Search

If an out-of-range condition exists when attempting an LTR tele-

phone call, the system search feature can be used to automatically search

for a system within range. If enabled, the system search mode is automat-

ically entered when the PTT switch is released. This mode is indicated by

a short tone and “SYS SRCH” on the bottom line of the display (see

following illustration).

The transceiver then attempts to access, in succession, other systems

that have a group programmed for telephone calls. As each system is

accessed, a beep sounds. If a system is accessed, the new system/group is

selected and a dial tone sounds. The telephone call must then be placed

within a few seconds or normal operation resumes. If no system could be

accessed, the intercept tone sounds, “NO PHONE” is displayed, the

system/group does not change, and the feature deactivates.

This mode can also be canceled at any time by pressing any front

panel option switch. If the menu mode SYS SRCH parameter is select-

able (see page 32), this feature can be turned on and off. Otherwise, it is

either enabled or disabled on all LTR systems by programming.

Transpond

The transpond feature indicates if the mobile being called is in

service. To be available, it must be programmed in the transceiver you are

calling. Each selectable LTR group can be programmed for this feature. If

CONVENTIONAL FEATURES

a call is received on one of these groups, the transceiver automatically

transmits a response. This causes the transceiver placing the call to

briefly unsquelch and the call indicator to turn on (if it is programmed on

the selected group).

Priority and Block ID Codes

LTR priority and block ID codes function nearly the same with both

LTR and Multi-Net operation. Therefore, refer to the Multi-Net descrip-

tion on page 46.

Transmit Inhibit

The Transmit Inhibit function operates the same with both LTR and

Multi-Net operation. Therefore, refer to the Multi-Net description on

page 47.

CONVENTIONAL FEATURES

Monitor Mode

The monitor mode is used to monitor a channel before transmitting.

When this mode is selected, it temporarily disables Call Guard squelch or

other squelch control techniques and also scanning so that all messages

occurring on the selected group (channel) are heard. The monitor mode is

enabled by taking the microphone off-hook (unless off-hook detection is

disabled by programming) or pressing the MON option switch. The

monitor mode is indicated by

in the display.

A conventional system must be selected to enable monitoring. If the

microphone is taken off-hook with a Multi-Net or LTR system selected,

scanning halts (unless off-hook detection is disabled) but monitoring is

not selected. The MON option switch is not detected when scanning is

enabled, and if it is pressed with a Multi-Net or LTR system selected,

NOT CONV is displayed and monitoring is not selected. This switch

must be pressed again to disable the monitor mode.

CONVENTIONAL FEATURES

A CG (Call Guard disable) option switch may also be programmed.

This switch disables both receive and transmit squelch control on the

selected group only (the monitor mode disables only receive squelch

control). When squelch control is disabled by the CG switch, “CG OFF”

is momentarily displayed. To re-enable squelch control and momentarily

display “CG ON”, press the CG switch again, select another system/

group, or cycle transceiver power.

If the Transmit Disable On Busy feature is used (see description

which follows), monitoring is performed automatically and the monitor

mode may not need to be used. Refer to “Monitoring Conventional Chan-

nels Before Transmitting” on page 42 for more information.

Transmit Disable On Busy

The Transmit Disable On Busy feature automatically disables the

transmitter if the selected group (channel) is busy when the PTT switch is

pressed. When the transmitter is disabled by this feature, the busy tone

sounds briefly and “DSBL BSY” is indicated on the lower line of the

display. The monitor mode (see preceding section) is enabled while the

PTT switch is pressed so that activity on the channel can be monitored.

However, it is not possible to access a channel by holding down the PTT

switch (it must be released to make another attempt).

Occasionally, a busy condition may be detected even though no one

is talking. To key the transmitter in this case, release the PTT switch and

then immediately press it again. There is also a programmable option

with this feature to allow transmitting with a busy channel if the correct

Call Guard signal is detected. The Transmit Disable On Busy feature is

enabled or disabled on each conventional group by dealer programming.

Receive-Only Groups

Conventional groups can be programmed for monitoring only (trans-

mitting is disabled). If the PTT switch is pressed with one of these groups

selected, the intercept tone sounds and “TX DSBL” is displayed.

CONVENTIONAL FEATURES

Talk-Around

Normally, all transmissions go through a repeater. Therefore, if you

are out of radio range of the repeater, you cannot talk to anyone, even if

you are only a short distance away from the mobile you are calling. To

allow communication if this occurs, the talk-around feature can be used

to enable direct mobile-to-mobile communication without going through

a repeater.

Each selectable group can be programmed for talk-around. It is then

automatically selected when the group is selected. There is no special

talk-around indicator although the group alpha tag on the lower line of

the display may be used to indicate this feature.

Talk-around can also be selected by the TALKARND menu param-

eter (see page 33) or T/A option switch. When talk-around is selected by

this switch, “TA ON” is flashed on the lower line of the display. Then

when it is disabled, “TA OFF” is flashed. Changing the selected system

or group, enabling scanning, or turning power off causes talk-around to

revert to the default condition programmed for the selected group.

Conventional systems can be programmed so that talk-around

cannot be selected. If an attempt is then made to enable talk-around with

the switch, “NO TALK” is flashed on the lower line of the display.

Groups may also be programmed so that talk-around cannot be turned

off. If the option switch is then pressed, neither “TA OFF” nor “TA ON”

is displayed. If the menu mode is used in these cases, the current mode

cannot be changed.

Call Guard Squelch

The Call Guard squelch feature eliminates distracting messages

intended for others using the channel. This is done by using a subaudible

tone or digital code to control the squelch. This tone or code is unique to

a user or a group on that channel. It is transmitted with the voice signal

but is not heard because it is in the subaudible range and attenuated by a

filter. Call Guard squelch can be programmed on each conventional

group. LTR operation uses ID codes to perform a similar function.

CONVENTIONAL FEATURES

Priority Group Sampling

The priority group sampling feature ensures that messages on

priority conventional groups are not missed while listening to a message

on a non-priority conventional group. A fixed first and second priority

group can be designated by programming or either priority group can be

the selected group. When a first priority group is selected,

displayed, and when a second priority group is selected,

is displayed

(see following illustration). When scanning, this symbol is displayed only

while a call is being received on the particular priority group.

When a message is detected on a first priority group while listening

to a non-priority message, a tone sounds, “PRIORTY1” is flashed on the

lower line of the display, and the transceiver changes to that system/group

to receive the message. Likewise, if a message is received on a second

priority group, “PRIORTY2” is displayed. When the priority message is

complete, the transceiver returns to the previous system/group. If a

message is still present, it is received.

When a priority system/group is sampled while listening to a

message on some other system/group, a series of “ticks” may be heard.

These ticks are brief interruptions of the audio signal that occur when

sampling takes place.

If the menu mode PRIORITY parameter (see page 33) or the PRI

option switch is available, priority sampling can be turned on and off.

When it is enabled by the switch, “PRI ON” is flashed, and if it is

disabled, “PRI OFF” is flashed. If this menu parameter or switch is not

available, priority sampling is either enabled or disabled by

programming.

MISCELLANEOUS

NOTE: Priority sampling occurs only on conventional systems and only

when scanning is enabled by the SCAN switch. It does not occur when

listening to a Multi-Net or LTR call or when transmitting.

MISCELLANEOUS

Supervisory Tones

The following tones are heard at various times when operating this

transceiver. Some or all of these tones can be disabled by the TONES

menu parameter or programming. Refer to “Tone Select” on page 32 for

more information.

Busy Tone - This tone is similar to the standard telephone busy tone, and

it indicates that the radio system is currently busy. It sounds with all

Multi-Net and LTR calls, but not conventional calls. Repeated access

attempts are made while the PTT switch is pressed with this tone

sounding. Therefore, the PTT switch does not need to be released to

access the system. The display indicates “BUSY” while this tone is

sounding.

Intercept Tone - This is a siren-like tone (alternating high and low tones)

which indicates the following out-of-range and error conditions:

• Out-Of-Range - If this tone sounds shortly after pressing the PTT

switch and “OUT RNGE” is displayed, the transceiver was unable to

contact a repeater. The usual cause for this is an out-of-range condition

(see “Operation At Extended Range” on page 61). Once this tone

sounds, no more access attempts are made until the PTT switch is

released and then pressed again. This condition is not indicated with

conventional operation.

• Time-Out Timer - If this tone sounds after the transmitter has been

keyed for an extended period and “TIMEOUT” is displayed, the trans-

mitter has been disabled by the Time-Out Timer feature (see page 31).

This tone sounds with Multi-Net, LTR, and conventional operation. Ten

MISCELLANEOUS

seconds before this tone sounds, a single beep sounds to indicate that

time-out will soon occur.

• Transmit Inhibit - If this tone sounds as soon as the PTT switch is

pressed with a Multi-Net or LTR system selected and “TX INHIB” is

displayed, the transmitter has been disabled by the Transmit Inhibit

feature (see page 47).

• Transmit Disable On Busy - If this tone sounds as soon as the push-to-

talk switch is pressed with a conventional system selected and “DSBL

BSY” is displayed, the channel is busy and the transmitter was disabled

by the Transmit Disable On Busy feature (see page 51).

• Receive-Only Channel - If this tone sounds as soon as the push-to-talk

switch is pressed with a conventional system selected and “TX DSBL”

is displayed, the channel is receive-only (see page 51).

• Tx While Receiving Call - If the push-to-talk switch is pressed while

receiving a Multi-Net or LTR call, this tone sounds and “DSBL BSY”

is displayed.

Proceed (Clear-To-Talk) Tone - This is a short tone which sounds after

the push-to-talk switch is pressed to indicate when talking can begin (see

page 30). A loud (two-pitch) tone may also be programmed.

Key Press Tone - This is a short tone that indicates when an option

switch is pressed (all modes).

Priority Call Tone - This is a short tone that sounds when a call is received

on a conventional first or second priority channel (see page 53).

Wrap-Around Tone - This is a two-pitch tone that indicates that the

highest or lowest channel was displayed and that wrap-around has

occurred.

Error Tone - This is a two-pitch tone that indicates that an error condition

has occurred.

MISCELLANEOUS

Multi-Net Telephone Call Tones

The following tones are generated by the Multi-Net equipment and

are heard when making a telephone, unique ID, or directed group special

call on a Multi-Net system.

Confirmation Tone - This is a short tone that sounds when the number

just dialed has been accepted by the system.

Call Proceed Tone - With Multi-Net directed group calls (see page 23),

ringing does not occur after the number is dialed. Instead, another short

tone sounds after the confirmation tone to indicate that the audio path is

complete and speaking can begin.

End Call Tone - Three beeps which indicate that the end of the call has

been detected by the system.

Proceed Dialing Tone - When placing a landside-to-mobile telephone

call (see page 25), the landside caller may enter a special number which

specifies the mobile being called. This tone indicates when that number

should be dialed.

LTR Telephone Call Tones

The following tones are generated by LTR interconnect equipment

and are heard when making LTR telephone calls. Therefore, if some other

type of interconnect equipment is being used, these tones may vary.

Reorder Tone - Three beeps which indicate that the call has been termi-

nated by the system.

Return Time Warning Tone - Two beeps which warn that you have not

transmitted for an extended period. If you do not transmit within 5

seconds, the call is automatically terminated by the system. The time

between transmissions is one of the parameters used by the system to

detect the end of a call when the # character is not sent.

MISCELLANEOUS

Conversation Time-Out Tone - Calls are limited to a certain length by

the system. Thirty seconds before this time is reached, a “tick” begins

sounding each second. When the 30-second time expires, the call is auto-

matically terminated by the system.

Turn-Around Tone - This is a single beep which may be used to indicate

to the landside party when to respond to your transmission. It sounds

when you release the PTT switch, and you may partially hear this tone.

Proceed Tone - This tone consists of two beeps and it tells the landside

caller when to enter the five-digit number specifying the mobile being

called. Dialing of this number must be started within 5 seconds of hearing

this tone, and a tone-type telephone must be used.

Display Messages

The following messages appear on the upper or lower line of the

display to indicate various operating modes and error conditions. The

group alpha tag appears in this area during normal operation.

ALL CALL - Indicates that a Multi-Net “All Call” special call is being

received. This is a high-priority call to all mobiles assigned to a site. If

another call is being received, it is dropped to receive this call.

BLK CALL - Indicates that the call is being received on a Multi-Net or

LTR block ID code (see “Calls on Priority and Block ID Codes” on

page 46).

BUSY - Indicates that the Multi-Net or LTR radio system is currently

busy (see “Busy Tone” on page 54).

System Operator Programming

As noted several times in this manual, programming determines the

availability and specific operation of many features. This refers to the

programming performed by your system operator when the radio was set

up, not to any programming that you can perform. If a feature is not

controlled by a front panel option switch, it is fixed in the mode set by

programming or not available. If you require additional information on

the operation of a feature, contact your system operator.

Speaking Into Microphone

For best results, hold the microphone about 1-2 inches from your

mouth and speak at a normal conversational level. Do not shout since it

distorts your voice and does not increase range. Make sure that the PTT

(push-to-talk) switch is pressed before you begin to speak and released as

soon as the message is complete. If the proceed tone is used, wait for that

tone to sound before speaking (see description on page 30).

Operation At Extended Range

When approaching the limits of radio range, the other party may not

be able to hear your transmissions and there may be an increase in back-

MISCELLANEOUS

ground noise when messages are received. You may still be out of range

even though you can hear a message. The reason for this is that the signal

you are receiving is usually transmitted at a higher power level than the

one transmitted by your transceiver. Communication may be improved by

moving to higher ground or away from shielding objects such as tall

buildings or hills.

Preventing Battery Discharge

In the standby mode (power on, not transmitting), transceiver power

consumption is relatively low. Therefore, you can probably leave the

transceiver on for one or two days without operating the vehicle and the

battery should not become seriously discharged. However, if the outdoor

temperature is low enough to significantly decrease battery capacity, the

transceiver should be turned off when not in use.

Since power consumption is significantly higher when transmitting,

it is good practice to have the vehicle running while transmitting. This

ensures that optimum power is being delivered to the transceiver and that

the battery does not become discharged.

Licensing

A government license is usually required to operate this transceiver

on the air. Your system operator will normally handle the licensing

requirements.

Transceiver Service

If your transceiver is not operating properly, “OUT-LOCK” or

“PROG ERR” may be displayed. To attempt to clear this condition, turn

power off and then on again to reset the control logic. Another indication

that could be displayed is “NO POWER”. This indicates that transmitter

temperature or supply voltage may be excessive. Release the PTT switch

and allow the transceiver to cool, and make sure that the vehicle battery

voltage is within the normal range.

MISCELLANEOUS

Also make sure that the controls are properly set and that the power,

external speaker (if used), and accessory (if used), cables are securely

plugged into the back of the transceiver. If the transceiver still does not

operate properly, return it to your system operator for service.

NOTE: There are no user-serviceable components in the transceiver.

Altering internal adjustments can cause illegal emissions, void the

warranty, and result in improper operation that can seriously damage the

transceiver.
