Wiring
ADVICE: Take a picture of the wiring before you start. and the setup screens
Fill in relevant information in the yellow areas.
Note the colours in the table opposite, If you have cables with the same colour mark the cables.

Note all the cable connections on your dispaly. You may have up to three transducers con-
nected simultainiously. In addition you may have NMEA, Pulse and alarm connections.
