Maintenance
To keep both your HDR 650 and your transducer working properly, perform the
following maintenance tasks 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 periods of time, algae and other marine
growth can reduce the effectiveness of the transducer. Periodically clean the face
of the transducer with hot water. 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 after it is returned to the water. Small air bubbles can
cling to the surface of the transducer and interfere with 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.
