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.
