Routine maintenance helps keep your equipment in good condition and prevents fu-
ture problems. Check the items shown in the table below on a regular basis to help
keep your equipment in good condition for years to come.

NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to plastic
parts or equipment coating.
Those items contain products that can
damage plastic parts and equipment
coating.
Remedy
Connect loosened cables. Replace any damaged
cables.
Remove dust with a dry, clean cloth. Do not use
commercial cleaners to clean the equipment - they
can remove paint and markings.
Wipe the LCD carefully to prevent scratching, us-
ing tissue paper and an LCD cleaner. To remove
dirt or salt deposits, use an LCD cleaner, wiping
slowly with tissue paper so as to dissolve the dirt or
salt. Change paper frequently so the salt or dirt will
not scratch the LCD. Do not use solvents such as
thinner, acetone or benzene for cleaning. Also, do
not use degreaser or anti-fog solution, as they can
strip the coating from the LCD.
Waterdrops on the LCD can slow touch response.
Wipe the LCD with a dry, soft cloth to remove the
water.
Foreign material can reduce sensitivity. Clean the
antenna with a cloth wetted with freshwater. Do not
use commercial cleaners to clean the radiator -
they can remove paint and markings.
Marine growth on the transducer face can reduce
sensitivity. Remove any growth with a wooden
stick or fine grade sandpaper.
