Operation
Turning on the Power
Press and hold the Power/Channel Selector.
Low-Voltage/High-Voltage Alert
If the power supply voltage exceeds 18VDC, an alert tone
sounds and dc HI flashes for 5 seconds. The power source
must not exceed 25VDC otherwise permanent damage
may occur to your radio, which may not be covered by the
manufacturer’s warranty.
NOTE
If the input voltage falls below 10VDC, dc Lo flashes for 5
seconds. The power turns off automatically if voltage falls
below 8.5VDC.
Switch your UH7700NB OFF and disconnect it from the power
source, before locating the cause of the power supply problem.
Setting the Squelch Level
Press the Power/Channel Selector momentarily. SqL shows and the
current squelch level will flash.
Turn the Channel Selector to select the desired squelch level.
UNIDEN UH7700NB
UHF CB Transceiver
10
Operation
oF(off) - squelch open.
1 - max sensitivity (min squelch)
5 - med sensitivity (med squelch)
9 - min sensitivity (max/tight squelch)
You must select a channel which is not in use before setting
the SQUELCH control. (see p.12 for “Selecting a Channel”).
NOTE
Think of the squelch control as a
gate. If you increase the squelch level
to maximum it raises the ‘Squelch
gate’ so only the strongest signals get
through.
If you decrease the squelch level to
minimum it lowers the ‘Squelch Gate’
to the extent that weak signals can
get through.
If unwanted weak and noisy signals
are getting through increase the
squelch level (‘Squelch Gate’) to a
medium level. Now only medium
and strong signals get through.

Operation
Recalling the Instant Channel
Momentarily press [INST] on the microphone at any time to return to the
Instant Channel. Press [INST] again to return to the previous channel.
Transmitting
The UHF CB Radio uses UHF-CB Channels.
For your reference a list of the available channels,
corresponding frequencies and guidelines for their use and
selection is printed on page 23. For Australia, Channels 05
and 35 are reserved for Emergency Calls.
NOTE
Select the desired channel. Press the microphone’s PTT button and
speak normally into the microphone. Hold it approx. 7cm from your mouth.
Release the [PTT] button to end the transmission and listen for a reply.
Call Function
Press [CALL] on the microphone. A three second ringing tone will
be transmitted. You may select from 5 types of tones (see p.18 for
“Selecting the Call tone”).
Current regulations require calling tones to be restricted to
one transmission per minute. If a second transmission is
NOTE
attempted within one minute then an error tone will sound.
Using Repeater Channels
UHF CB Repeaters are used to retransmit or relay your signal. Repeaters
will extend the range of your radio and overcome the shielding effect caused
by solid obstructions. In normal Simplex operation, your radio transmits on
one particular frequency and receives on that same frequency.
If there is a barrier that partially blocks your transmitted signal, the
probability of another radio receiving the signal is very slim. Hills, tall
buildings, metallic structures,...etc tend to act as a screen between radios.
UNIDEN UH7700NB
UHF CB Transceiver
13
Operation
Standard Operation without the aid of a Repeater station.
Operation with the aid of a Repeater Repeater Station (Duplex).
The signal coming from your radio is received by the Repeater Station
and the re-transmitted at the same time on another channel. This
operation is called “Duplexing”.
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32
etc...
If you transmit on CH01 Duplex mode, you are actually transmitting
on CH31 the repeater station down-converts your signal and
retransmits on CH01.

UHF CB Channel Guidelines
Always listen on a channel (or observe the receive signal level
meter) to ensure it is not already being used before transmitting.
Channels 5 and 35 are used for emergency channels.
CTCSS and DCS will not operate on these channels.
Please follow these guidelines for channel use in Australia:
• Channels 05 and 35 are Emergency Channels.
• Channel 11 is a Calling Channel.
• Channels 22 and 23 are for telemetry and telecommand
applications, channels 61, 62 and 63 are for future use and TX is
inhibited on these channels.
NOTE
General communication is accepted on all other channels
with these guidelines:
• Channel 40 - road channel (Australia).
• Channels 01-08 (and 31-38), and Channels 41-48
(and 71-78) are repeater channels.
Important information - 80 Channel UHF CB channel expansion
To provide all users additional channel capacity within the UHF CB
Band. The ACMA will change the majority of the current wideband 40
channel use to narrowband channel use. This allows for additional
channels to be added, up to 80 Channels.
This simply means that the new narrowband radio you have purchased
will have more channels than older radios. Please refer to the guidelines
above and the channel chart for further channel information.
A list of currently authorised channels can also be obtained from the
ACMA website in Australia and the MED website in New Zealand.
Interference / Poor Audio
When a new narrowband radio receives a signal from an older
wideband radio the speech may sound loud - however the
UH7700NB’s built-in AVS (Automatic Volume Stabilizer) circuitry will
detect and manage incoming audio to comparable levels.
NOTE
Narrowband radios operating on CH41 - CH80 may encounter
interference from a nearby wideband radios transmitting on high
power on an adjacent channel (frequency).
When an older wideband radio receives a signal from a new
narrowband radio the speech may sound quiet - the wideband radio
user simply adjusts their radio volume for best performance.
The above situations are not a fault of the radio but a symptom of mixed
wideband and narrowband radios in current use. It is expected that as
older wideband radios are phased out this issue will be eliminated.

Warranty
Statement of Remedy: If the Product is found not to conform to this warranty
as stated above, the Warrantor, at its discretion, will either repair the defect or
replace the Product without any charge for parts or service. This warranty does
not include any reimbursement or payment of any consequential damages
claimed to arise from a Product’s failure to comply with the warranty.
Our goods come with guarantees that cannot be excluded under the Australian
Consumer Law. You are entitled to a replacement or refund for a major failure
and for compensation for any other reasonably foreseeable loss or damage.
You are also entitled to have the goods repaired or replaced if the goods fail to
be of acceptable quality and the failure does not amount to a major failure.
This warranty is in addition to and sits alongside your rights under either the
COMPETITION AND CONSUMER ACT 2010 (Australia) or the CONSUMER
GUARANTEES ACT (New Zealand) as the case may be, none of which can be
excluded.
Procedure for obtaining warranty service: Depending on the country in
which the Product was first purchased, if you believe that your Product does
not conform with this warranty, you should deliver the Product, together with
satisfactory evidence of your original purchase (such as a legible copy of the
sales docket) to Uniden at the addresses shown below. You should contact
Uniden regarding any compensation that may be payable for your expenses
incurred in making a warranty claim. Prior to delivery, we recommend that you
make a backup copy of any phone numbers, images or other data stored on
your Product, in case it is lost or damaged during warranty service.
