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 the cables that have loosened.
Replace any damaged cables.
Remove dust with a dry clean cloth. Do
not use commercial cleaners to clean
the equipment. Those cleaners can re-
move paint and markings.
Wipe the LCD carefully to prevent
scratching, using tissue paper and an
LCD cleaner. To remove dirt or salt de-
posits, use an LCD cleaner, wiping
slowly with tissue paper so as to dis-
solve the dirt or salt. Change paper fre-
quently so the salt or dirt will not scratch
the LCD. Do not use solvents such as
thinner, acetone or benzene for clean-
ing. Also, do not use degreaser or anti-
fog solution, as they can strip the
coating from the LCD.
Wipe the LCD with a dry cloth to remove
the water. Waterdrops on the LCD can
cause slow touch response.
