Note: If your system requires both a Y-cable and a transducer exten-
sion cable, ensure that you connect the Y-cable to the sounder module
and the extension cable to the transducer.
The connector pins are shown in the following diagram, together
with the connections and wire colors; this is information is pro-
vided as an aid to fault diagnosis.
WARNING:
Do not cut the transducer cable or remove the connector.
Do not try to shorten or splice the cable. Cutting the transducer
cable will severely reduce sonar performance.
If the cable is cut, it must be replaced—it cannot be repaired.
Cutting the cable will also void the warranty.
