MAINTENANCE
Your 450TX is designed to provide years of trouble free operation with
virtually no maintenance. Follow these simple procedures to ensure your
450TX 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 450TX 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 450TX 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.
