Maintenance schedule
Check and measures
Dust and dirt may be removed
from these units with a soft
cloth.
The LCD will in time
accumulate a layer of dust
which can dim the picture.
Wipe the LCD carefully to
prevent scratching, using
tissue paper and an LCD
cleaner. To remove stubborn
dirt, use an LCD cleaner,
wiping slowly with tissue
paper so as to dissolve the
dirt. Change paper frequently
so the dirt will not scratch the
LCD.
Clean the filter at the rear of
the processor units if it is
dusty.
Check that all cabling is
firmly connected and is not
damaged.
Exposed bolts and nuts are
subject to corrosion. Further,
they may loosen by vibration.
Dust, dirt and salt deposits on
the radiator cause signal
attenuation, resulting in loss
of sensitivity. Wipe radiator
with a freshwater-moistened
cloth.
Check that all terminals and
connectors on circuit boards
are securely fastened.
Check that all screws are
tightly fastened.
Remarks
Do not use chemical-based cleaners
for cleaning. They can remove paint
and markings.
Check that bolts and nuts are securely
fastened. Refasten if necessary. If
corroded, clean and coat with
anticorrosive sealant.
