8.2 Unit cleaning instructions

The unit does not require regular cleaning. However, if you find
it necessary to clean the unit, please follow the steps below:
1. Ensure power is switched off.
2. Wipe unit clean with a damp cloth.
3. If necessary, use a mild detergent solution to remove grease
marks.
Transducer care and cleaning
Growth can collect on the bottom of the transducer, this can
reduce performance. To prevent the build-up of sea growth, coat
the transducer with a thin layer of water-based antifouling paint,
available from your local marine dealer. Reapply paint every 6
months or at the beginning of each boating season. Certain
smart transducers have restrictions on where antifouling paint is
applied. Please consult your dealer.
Note: Transducers with a temperature sensor may not work
properly if painted.
Note: Never use ketone-based paint. Ketones can attack
many plastics, possibly damaging the sensor.
Note: Never use spray paint on your transducer. Spraying
incorporates tiny air bubbles, and a marine transducer cannot
transmit properly through air.
Use a soft cloth and mild household detergent to clean the
transducer. If the fouling is severe, remove the growth with
a tough cleaning pad, such as a green Scotch Brite
for example. Be careful to avoid scratching the face of the
transducer.
Note: Harsh cleaning solvents such as acetone WILL damage
the transducer.
