MAINTENANCE
Your 150SX is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
150SX continues to deliver top performance.
• If the unit comes into contact with salt spray, simply wipe the affected
surfaces with a cloth dampened in fresh water. Do not use a chemical
glass cleaner on the lens. Chemicals in the solution may cause cracking in
the lens of the unit.
• 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, algae and
other marine growth can reduce the effectiveness of the transducer.
Periodically clean the face of the transducer with liquid detergent.
Pivoting the transducer up in the bracket may allow better access for
inspection or cleaning.
• 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 cling to the surface of the transducer and interfere with
proper operation. These bubbles dissipate with time, or you can wipe
the face of the transducer with your fingers after the transducer is in
the water.
• Never leave the 150SX in a closed car or trunk—the extremely high
temperatures generated in hot weather can damage the electronics.
