MAINTENANCE/TROUBLESHOOTING

MAINTENANCE

Your 320 is designed to provide years of trouble free operation with virtually
no maintenance. Follow these simple procedures to ensure your 320 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 320 in a closed car or trunk—the extremely high temperatures
generated in hot weather can damage the electronics.

TROUBLESHOOTING

Do not attempt to repair the 320 yourself. There are no user serviceable parts
inside, and special tools and techniques are required for reassembly to ensure
the waterproof integrity of the housing. Repairs should be performed only by
authorized Teleflex technicians.
Many requests for repair received by Teleflex involve units that do not actually
need repair. These units are returned "no problem found." If you have a
problem with your 320, use the following troubleshooting guide before calling
Customer Support or sending your unit in for repair. The 320 contains several
tools that can aid in determining if there is a problem and how to isolate and
repair the problem in many cases.
