MAINTENANCE AND WARRANTY

WARRANTY

are two adjustments available to you—height, and running angle. Make small adjustments and run the boat at high speeds to determine the effect. It may take several tries to optimize high speed operation. This can also be a result of air or turbulence in the transducer location caused by rivets, ribs, etc.

7. My unit loses power at high speeds.

Your 150SX has over-voltage protection that turns the unit off when input voltage exceeds 20 VDC. Some outboard motors do not effectively regulate the power output of the engine’s alternator and can produce voltage in excess of 20 volts when running at high RPMs. The 150SX displays input voltage in the Diagnostic screen. Use this readout to determine if the voltage exceeds 20 VDC.

Use a voltage regulator or conditioner that provides 12 VDC output over a wide range of input voltages. SureVolt™ from Humminbird is a recommended unit, providing 12 VDC out with inputs from 6 VDC to 23 VDC.

8. The screen begins to fade out. Images are not as sharp as normal.

Check the input voltage using Diagnostic. The 150SX will not operate on input voltages below 10 VDC. See 7 above.

9.The display shows many black dots at high speeds and high sensitivity settings.

You are seeing noise or interference caused by one of several sources. Noise can be caused by other electronic devices. Turn off any nearby electronics and see if the problem goes away. Noise can also be caused by the engine. If engine noise is causing the interference, the problem will intensify at higher RPMs. Increase the engine speed with the boat stationary to isolate this cause. Propeller cavitation can appear as noise on- screen. If the transducer is mounted too close to the propeller, the turbulence generated can interfere with the sonar signal. Ensure that the transducer is mounted at least 15" (38cm) from the prop.
