Cleaning Instructions
Cleaning the Display and Sounder Module
WARNING:
Take care when cleaning the display. Use the display cleaning cloth
provided. Avoid wiping the display screen with other types of dry cloth -
this could scratch the screen coating.
Do not use acid, ammonia based or abrasive products.
• Ensure power is off, wipe the display clean with a damp cloth.
• If necessary, use IPA (isopropyl alcohol) or a mild detergent solution to
remove grease marks.
Cleaning the Transducer
Sea growth can collect quickly on the bottom of the transducer, this can reduce
the performance in just a few weeks. To prevent the build-up of sea growth,
coat the transducer with a thin layer of paint. Use only a water-based
antifouling paint, or a water-based paint specifically designed for transducers.
Apply the paint with a brush.
If your transducer becomes fouled or stops working because of sand or sea
growth, use a stiff brush to clean it. You may sand the surface with a fine-grit
wet or dry sandpaper (#320 grade or finer), but this will affect the performance
of the unit when the boat is moving at higher speeds.
The paddle wheel mechanism may become jammed by dirt, grit or barnacles.
Work the contaminant out of the mechanism, then clean the unit with soap and
water or alcohol.
Cleaning the Hull
Use caution when sanding or cleaning the outside of the hull near the
transducer.
WARNING:
Harsh cleaning solvents such as acetone may damage the transducer.
