ICE Flasher Series™ Fishfinder Doesn’t Power Up

If your ICE Flasher Series™ control head doesn’t power up, refer to the Installation section, and make sure that:

•the power cable is properly connected to the ICE Flasher Series™ Fishfinder;

•the power cable is wired correctly, with red to positive battery terminal and black to negative terminal or ground;

•the battery voltage of the power connector is between 10.5 and 20 VDC.

Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.

No Bottom Reading on the Display

If there is no bottom reading visible on the display, there are a number of possible causes for this condition, including:

•check the transducer cable connection on the back of the ICE Flasher Series™ control head and make sure that the cable to the transducer has not been cut or pinched, as even a small abrasionin the cable can affectperformance significantly.

No Continuous Depth Display in Very Shallow Water

Losing continuous depth when the transducer is in very shallow water is normal, because the automatic range control cannot lock onto the bottom in depths of one foot or less.

Screen Fades, Images Are Not Sharp

If the screen begins to fade, and images are not as sharp as normal, check the input voltage. The ICE Flasher Series™ will not operate on input voltages below 10.5 VDC.
