Maintenance

To keep both your HDR 650 and your transducer working properly, perform the following maintenancetasks as needed.

HDR 650 Maintenance

If your HDR 650 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, as chemicals in the solution 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.

WARNING: Never leave your HDR 650 in a closed car or trunk; the extremely high temperatures generated in hot weather can damage the electronics.

Transducer Maintenance

If your boat remains in the water for long periodsof time, algae and other marine growth can reduce the effectivenessof the transducer.Periodicallyclean the face of the transducer with hot water. Pivoting the transducer up in the bracket may allow better access for inspectionor cleaning.

If your boat remains out of the water for a long period of time, it may take some time to wet the transducerafter it is returnedto the water. Small air bubbles can cling to the surface of the transducerand interferewith proper operation. These bubbles will dissipate with time, or you may wipe the face of the transducer with your fingers after the transducer is in the water.
