Maintenance
Your Humminbird® Portable fishfinder is designed to provide years of trouble-free
operation with virtually no maintenance. Follow the simple procedures below to
ensure that your Humminbird® Portable continues to deliver top performance.
If the Portable case comes into contact with salt spray, wipe the affected surfaces
with a lint-free cloth, then apply a commercially available anti-corrosive treatment
to all exposed electrical contacts.
If the portable case bag becomes dirty, clean the bag with mild soap, water, and
a soft rag or brush and then hang it up to dry.
Do not use a chemical glass cleaner on the lens - this 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.
If your boat remains in the water for long periods of time, marine growth can
reduce the effectiveness of the transducer. Periodically clean the face of the
transducer with liquid detergent.
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 your Humminbird® Portable unit in a closed car or trunk - the extremely
high temperatures generated in hot weather can damage the electronics. Repairs
should be performed only by authorized Humminbird® technicians.
How to Remove Water from the Portable Case
Open the front zipper and pull the case down to allow water to exit the case. If
needed, remove the case from the plastic base and air-dry it. Follow recommended
maintenance procedures for salt spray exposure if needed.
