INSTALLATION
TEST THE INSTALLATION
TEST THE INSTALLATION
Testing should be performed with the boat in the water, however you can initially
confirm basic operation with the boat trailered.
Press POWER once to turn the unit on. There will be an audible chirp when any button
is pressed to confirm the button press. If the unit does not power-up, ensure the unit is
fully seated on the mount and that power is available.
The first screen provides four options: Start-up, Options, Simulator, and Diagnostic. A
message at the bottom of the screen indicates the transducer connection. If no
transducer is detected (or one is not connected), the message will indicate this and the
unit will go into simulator after the initial screen times out.
Note: the transducer must be submerged in water for reliable transducer
detection.
If a transducer is detected, the unit will enter “Start Up” or normal operation unless you
choose another option. If you do not press any button before the timer reaches “0”, the
normal operation screen is displayed. If the boat is in water, sonar data appears.
If the bottom is visible on screen with a digital depth readout, the unit is working
properly. Ensure the boat is in water greater than 2’ but less than the depth
capability of the unit and the transducer is fully submerged. Remember the sonar signal
cannot pass through air.
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. Refer to the appropriate
transducer installation section for more detail.
Note: it is often necessary to make several incremental transducer adjustments
before optimum high-speed performance is achieved.
Important: For Transom Mount transducer installations, install the third mounting screw
after the final transducer adjustments.
