virtually no maintenance. Follow these simple procedures to ensure your
PiranhaMAX™ continues to delivertop performance.
If the unit comes into contact with salt spray, wipe the affected surfaces with a
clothdampened in fresh water.
Do not use a chemical glass cleaner on the lens - this may cause cracking in
the lens.
When cleaning the LCD protective lens, use a chamois and non-abrasive, mild
cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid
scratching the lens.
If your boat remains in the water for long periods of time, marine growth can
reduce the effectiveness of the transducer. Periodically clean the face of the
transducer with liquiddetergent.
If your boat remains out of the water for a long period of time, it may take some
time to wet the transducer when returned to the water. Small air bubbles can
clingto the surface of the transducer and interfere with proper operation. These
