is too short, extension cab es 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.

NOTE: The transducer can pivot up to 90 degrees in the bracket. Allow enough slack in the cable for this movement. It is best to route the cable to the side of the transducer so the transducer will not damage the cable during movement.

2a. If you are routing the cable over the transom of the boat, secure the cable by attaching the cable clamp to the transom, drilling 9/64" diameter holes for #8 x 5/8" wood screws, then skip directly to procedure 5, Connecting the Cable.

immediately.

 

3.Place the escutcheon plate over the cable hole and use it as a guide to mark

the two escutcheon plate mounting holes. Remove the plate, drill two 9/64" diameter x 5/8" deep holes, and then fill both holes with marine-grade silicone sealant. Place the escutcheon plate over the cable hole and attach with two #8 x 5/8" wood screws.

NOTE: If there is excess cable that needs to be gathered at one location (as shown in the illustration), dress the cable routed from both directions so that a single loop is left extending from the storage location. Doubling the cable up from this point, form the cable into a coil. Storing excess cable using this method can reduce electronic interference.

5. Connecting the Cable

Insert the transducer cable into the appropriate terminal slot. The cable connectors are labeled, and there are corresponding labels on the cable holder on the rear of the control head. The slots are keyed to prevent reversed installation, so be careful not to force the connector into the holder. Refer to your manual and/or control head installation guide for the correct procedure for installing the cable connectors to the control head.

1.Plug the other end of the transducer cable back into the control head connection holder.

Your control head is now ready for operation.
