cause your eyes to get tired. Allow your eyes to rest at
intervals.

Maintenance Procedures
Dirt on the cabinet
zGently clean dirt on the cabinet with a soft cloth. In the
case of heavy soiling, soak a cloth in water, wring dry and
wipe, followed by wiping again with a dry cloth.
Pay attention to the following as the cabinet may
deteriorate in condition or paint may come off.
• Do not wipe with thinner or benzene
• Do not spray volatile chemicals like insecticide
• Do not allow prolonged contact with rubber or plastic
products
Dirt in the air inlets
zUse a vacuum cleaner to suck up the dirt. Otherwise, use
a cloth to wipe off the dirt. If dirt is allowed to accumulate
in the air inlets, the internal temperature cannot be
adjusted and this may cause a malfunction.
Dirt on the lens
zClean the dirt using commercial blowers or lens cleaning
papers for cleaning glasses and cameras.
Do not use fluid-type cleaning agents. This may lead to
peeling of the surface coating film.

When transporting this unit for repair or during house
moving, attach the buffer material on the top and bottom of
