Connecting the Control Heads to the Switch and the Transducer

1. Connect the transducer and the Control Heads to the Unit Switch, referring to the illustration for guidance.

2. Remove the connector holder from your control heads and insert the cable connector from the Unit Switch into

the connector holder.

CAUTION: The slot for the connector is keyed to prevent reversed installation, so do not force the connector into the holder.
See the Installation section of your operations manual for additional information.

Connecting the Cables

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as
possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too
short, extension cables are available to extend the transducer cable up to a total of 50'. For assistance, contact the Customer
Resource Center at www.humminbird.com or call 1-800-633-1468 for more information.

1. Insert the Unit Switch cable connectors into the appropriate slots of the connector holder on each control head.

The cable connectors are labeled, and there are corresponding labels on the connector holder on the rear of each
control head. The slots are keyed to prevent reversed installation, so be careful not to force the connector into
the holder.

Your control heads are now ready for operation.
