Cleaning the lens
■ Use a commercially available blower or lens
cleaning paper (for glasses and camera lenses)
for cleaning the lens. Do not use any liquid type
cleaning agents, as they may wear off the coat-
ing film on the surface of the lens.
■ As the surface of the lens can easily get dam-
aged, be sure not to scrape or hit the lens.
Cleaning the exhaust and intake vents
■ Use a vacuum cleaner to clean dust from the
exhaust vent and the intake vent.
Maintenance
Cleaning the projector
■ Be sure to unplug the power cord before clean-
ing the projector.
■ The cabinet as well as the operation panel is
made of plastic. Avoid using benzene or thinner,
as these can damage the finish on the cabinet.
■ Do not use volatile agents such as insecticides
on the projector.
Do not attach rubber or plastic items on the pro-
jector for long time.
    The effects of some of the agents in the plastic
may cause damage to the quality or finish of the
projector.
■ Wipe off dirt gently with a soft flannel cloth.
■ When the dirt is hard to remove, soak a cloth in a
neutral detergent diluted with water, wring the
cloth well and then wipe the projector.
Strong cleaning detergents may discolor, warp
or damage the coating on the projector.
Make sure to test on a small, inconspicuous area
on the projector before using.
