MAINTENANCE AND WARRANTY
MAINTENANCE/TROUBLESHOOTING
• 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. Peri-
odically 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 Tracker unit 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 Tracker unit 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 actu-
ally need repair. These units are returned “no problem found.” If you have a
problem with your Tracker unit, use the following troubleshooting guide before
sending your unit in for repair. The Tracker unit contains several tools that can
aid in determining if there is a problem and how to isolate and repair the prob-
lem in many cases.
