7.My unit loses power at high speeds.

Your PiranhaMAX™ 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’salternator and can produce voltage in excess of 20 Volts when running at high RPMs.

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

Check the input voltage. ThePiranhaMAX™ will not operateon input voltages below 10 VDC.

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

You are seeing noise or interference caused by one of severalsources.Noise can be caused by 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 also appear as noise on the display.If the transducer is mounted too close to the propeller,the turbulence generatedcan interfere with the sonar signal. Make sure that the transduceris mounted at least 15" (380 mm) from the propeller.
