Testing the Installation

After installation is complete and all connections are made, you are ready to test the installation prior to actual use. Thorough testing should be performed with the boat in 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 that confirms the button press. If the unit does not power-up, ensure that the unit is fully seated on the mount and that power is available.

The first screen provides three options; Start-up, Simulator, and Diagnostic. The time remaining before the screen "times-out" is shown at the bottom of the screen. If you do not press any button before the timer reaches 0, the normal operation screen will be displayed. If the boat is on-water, sonar data will begin to appear.

If the bottom is visible on-screen with a digital depth readout, the unit is working properly. If the unit powers-up but fails to display bottom information, the transducer is not properly connected. Ensure that the boat is in water

greater than 2' but less than 600' deep, and that the transducer is fully submerged. Remember that the sonar signal cannot pass through air. Refer to the troubleshooting section of this manual. 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 installation 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.

The Wide 128 is completely automatic and easy to use. Simply press the POWER button and the unit will locate and track the bottom from 2' to 600' changing ranges as necessary, display any structure or suspended fish and work at speeds from 0 to over 70 mph.

If POWER is the only button you use, you will benefit from the advanced automatic bottom tracking of the Wide 128. However, if you choose to experiment with the many features and controls the Wide 128 offers, you can customize the presentation of information to suit your particular needs.
