Maintenance program
Item Check point Remedy
Display unit
connectors Check for tight connection. Tighten loosened connectors.
LCD
The LCD will, in time,
accumulate a coating of
dust which tends to dim the
picture. Wipe the LCD carefully to prevent
scratching, using 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.
Ground terminal
Check for tight connection
and corrosion. Clean or replace ground wire as
necessary.
