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.
