7.2 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 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 green scotch brite
TM
pad. Be careful to avoid scratching the transducers face.
If your transducer has a paddlewheel you can wet sand with fine grade wet/dry paper.
Note:
Harsh cleaning solvents such as acetone may damage the transducer.
