Storing Excess Cable

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.

6. Test and Finish the Installation

Once you have installed both the control head and the transom transducer, and have routed all the cables, you must perform a final test before locking the transducer in place. Testing should be performed with the boat in the water, although you can initially confirm basic operation with the boat out of the water.

1.Press POWER once to turn the control head on. If the unit does not power up, make sure that the connector holder is fully seated in the receptacle and that power is available.

2.If all connections are correct and power is available, the Humminbird® control head will enter Normal operation.

3.If the bottom is visible on-screen with a digital depth readout, the unit is working properly. Make sure that the boat is in water greater than 2' but less than the depth capability of the unit, and that the transducer is fully submerged, since the sonar signal cannot pass through air.

NOTE: The transducer must be submerged in water for reliable transducer detection.

4.If the unit is working properly, gradually increase the boat speed to test high-speed performance. If the unit functions well at low speeds, but begins to skip or miss the bottom at higher speeds, the transducer requires adjustment.

5.If you have the correct angle set on the transducer, yet lose a bottom reading at high speed, adjust the height and the running angle in small increments to give you the ideal transducer position for your boat. First, adjust the height in small increment.
