·
The installation includes 6 major steps:  
1. Read the installation and operation manual.  
2. Plan where to install the transducer and instrument.  
3. Install the transducer, then the instrument.  
4. Run the cables.  
5. Take a break and admire your installation.  
6. Learn the functions and calibrate your instrument.  
·
Before you begin drilling... think about how you can make the installation  
as neat and simple as your boat will allow. Plan where to position the  
instrument. Think about leaving space for additiona instruments in the  
future.  
·
-
A few ”do not’s” you should consider:  
Do not cut cables too short. Allow extra cable length at the instrument so it  
can be removed for inspection without having to disconnect attached  
cables.  
-
-
Do not place sealant behind the instrument. The instrument gasket  
eliminates the need for sealant.  
Do not run cables close to fluorescent light sources, engine or radio  
transmitting equipment to avoid electrical disturbances.  
-
·
Do not rush, take your time. A neat installation is easy to do.  
The following material is needed:  
Wire cutters and strippers.  
Large Philips and small flat head screw driver.  
Hole saw for the instrument clearance hole, 52 mm (2 1/16”).  
2.8 mm (7/64 ”) drill for the mounting holes in wood.  
3.2 mm (1/8 ”) drill for the mounting holes in fibre glass.  
Plastic cable ties.  
If you are doubtful about the installation, obtain the services of an  
 
experienced technician.

2.1 Installing the instrument  
·
Place the adhesive drill template on the desired location for the instrument.  
Drill the four screw holes using a 2.8 mm (7/64”) drill for wood or 3.2 mm (1/8”)  
for fibre glass. Use a 52 mm (2 1/16”) hole saw to machine the clearance  
hole for the instrument connection socket.  
Note! Never drill through the instrument’s four mounting holes as the  
gasket may be damaged and thus cause leakage. The warranty is not valid  
for damage caused by drilling through the mounting holes.

Position  
The position is displayed in latitude and longitude to three  
decimal places. If the NMEA Navigator just sends two  
decimals, the third will always read zero.  
3.2.1 Time and date  
To display date and time, press DOWN. Date and time is  
displayed in month, day, hour, minute and second. Some  
NMEA navigators does not send date. In that case, the  
text TIME is written instead of the date. To set the local  
time zone, press KEY. The ”underline” sign is flashing  
(underline is the same as plus), change with UP or DOWN,  
move to next character with MODE, change value with UP  
or DOWN. When you have entered the correct time zone,  
press KEY.  
3.2.2 Battery voltage  
To display battery voltage, press DOWN. Battery voltage is  
measured in the instrument. It can therefore be different to  
the voltage meter in your boat. That is due to voltage drop  
in cables.

To change to combi steer, press MODE. The combi steer  
window provides you with information of five values at a  
time. The arrow at the top helps you to keep on track. This  
function is explained in section 3.3.7. The functions  
displayed are speed over ground, course over ground,  
distance to Waypoint and course to Waypoint. If no  
Waypoint is selected to navigate towards in the NMEA  
navigator, the bottom row will display dashes.  
3.3.1 Cross track error (XTE)  
To display XTE, press DOWN. The XTE window displays  
the XTE numerical on the top row. Bottom row displays  
distance to and course to Waypoint. If no Waypoint is  
selected to navigate towards in the NMEA navigator, the  
bottom row will display dashes.  
3.3.2 Waypoint closure velocity (WCV)  
To display WCV, press DOWN. The WCV window displays  
the WCV numerically on the top row. Bottom row displays  
distance and course to Waypoint. If no Waypoint is  
selected to navigate towards in the NMEA navigator, the  
bottom row display dashes. If your boat is moving away  
from the Waypoint, WCV will display dashes.  
3.3.3 Time To Go (TTG)  
To display TTG, press DOWN. The TTG window displays  
the time to Waypoint. If no Waypoint is selected to navigate  
to in the NMEA navigator or if your boat is moving away  
from the Waypoint, TTG will display dashes.

NMEA input  
The NMEA is connected as explained in section 2.1. It is important to know that  
the Star NAV Repeater only can repeat what is sent from the NMEA navigator it  
is attatched to. Some NMEA navigators do not send all necessary data. It is  
also important to know that some information is present only after selecting a  
Waypoint in the NMEA navigator.
