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 LCD lightly with soft

cloth to remove dust.

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.
