MAINTENANCE
Your 350TX is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
350TX 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 350TX 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 350TX 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 Humminbird technicians.
Many requests for repair received by Humminbird involve units that do not
actually need repair. These units are returned “no problem found.” If you
have a problem with your 350TX, use the following troubleshooting guide
before sending your unit in for repair. The 350TX contains several tools that
can aid in determining if there is a problem and how to isolate and repair
the problem in many cases.
