Cleaning the display
CAUTION: Take care when cleaning the displays. Do not wipe a display
screen with a dry cloth - this could scratch the screen coating. Do not
use acid, ammonia based or abrasive products.
1. Ensure the display is switched off.
2. Wipe the display with a clean, damp cloth.
3. If necessary use iso-propyl alcohol (IPA) or a mild detergent solution to remove
grease marks.
Sounder module
Routine checks
The sounder module is a sealed unit. Maintenance procedures are therefore limited to
the following periodic checks:
• Examine the cables for signs of damage, such as chafing, cuts or nicks.
• Check that the cable connectors are firmly attached.
Cleaning the module
The sounder module is a sealed unit and does not require regular cleaning. However, if
it is found to be necessary to clean the unit:
1. Ensure the display is switched off.
2. Wipe the display with a clean, damp cloth.
3. If necessary use iso-propyl alcohol (IPA) or a mild detergent solution to remove
grease marks.
Transducer
CAUTION: Harsh cleaning solvents such as acetone may damage the
transducer.
Sea growth can collect quickly on the bottom of the transducer, this can reduce
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 water-based antifouling paint, or a water- based paint specifically designed
for transducers. Apply the paint with a brush.
If the transducer becomes fouled or stops working because of sand or sea growth, use
a stiff brush to clean it. The surface can be sanded 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.
