  NOTE: During a typical installation, use only

the Red and Black wires. The other wires do not 

have to be connected for normal operation of the 

unit. For information on connecting to a NMEA 

or CANet compatible device, see 

page 41.

1.  Use a test light or voltmeter to determine the 

polarity of the voltage source.

2.  Connect the Red (+ or positive) wire to the 

positive voltage terminal. (If you use the boat’s 

fuse block, route the positive connection 

through the fuse, as shown on the diagram.)

3.  Connect the Black (- or ground) wire to the 

negative voltage terminal.

4.  Install or check the 3-Amp fuse (on the boat’s 

fuse block or in the in-line holder).

5.  Align the notches on the cable plug and on 

the back of the unit. Insert the cable into the 

connector, and turn the lock ring counter-

clockwise until it stops.
