Raw Sonar

Note: Piranha 5’s dual beam feature indicates the depth of the return and the beam that the return comes from. Returns from the narrow beam are shown with solid fish icons while the wide beam returns are displayed with hollow fish icons.

Bottom Black Mode

Chart Speed (Setting Saved in Memory) Press POWER-MENU until the Chart menu appears. Select a setting from 1-5 to match your display to

both boat speed and present depth. Faster speeds in shallow water should be matched with a higher chart speed setting while slower speeds and deeper waters will best be viewed at a slower setting. Become familiar with this feature by traveling the same course over known bottom detail at various speeds and settings.

Maintenance

Your Piranha is designed to provide years of trouble-free operation with vir- tually no maintenance. Follow these simple procedures to ensure your Piranha continues to deliver top performance.

If the unit comes into contact with salt spray, wipe the affected surfaces with a cloth dampened 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 liquid detergent.
