Transom Transducer Installation

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.

1.Press POWER once to turn the control head on. If the unit does not power up, make sure that the connector is fully plugged into the terminal slot 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 transducermust be submergedin water for reliabletransducerdetection.

4.If the unit is working properly, gradually increase the boat speed to test high-speedperformance.If the unitfunctions wellat lowspeeds,butbegins 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 increments (Figure 23).

NOTE: The deeper the transducer is in the water, the more likely that a rooster tail of spray will be generated at high speeds, so make sure that the transduceris as high as it can be and still be submerged in the water.

If you are still not getting good high speed readings, you may need to disassemble the transducer mounting assembly and re-position the ratchets (Figures 18a - 18d).

If you do change the transducer position, re-trace the position of the mounting bracket before proceeding.
