Cleaning the air vents and the intake vent cover
■ Use a vacuum cleaner to clean dust from the ex-
haust vent, the intake vents and the intake vent cover
(on the bottom of the projector).
Info
• If you want to clean the air vents and the intake
vent cover during projector operation, ensure
you press
on the projector or on the
remote control and put the projector into standby
mode. After the cooling fan has stopped, unplug
the power cord from the AC socket and clean
the air vents and the intake vent cover.
Cleaning the exhaust and intake vents
Cleaning the projector
■ Ensure the power cord is unplugged 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 to the projec-
tor for long periods.
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
mild 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 projec-
tor before use.
Cleaning the lens
■ Use a commercially available blower or lens clean-
ing paper (for glasses and camera lenses) for clean-
ing the lens. Do not use any liquid type cleaning
agents, as they may wear off the coating film on the
surface of the lens.
■ As the surface of the lens can easily get damaged,
be careful not to scrape or hit the lens.

Cleaning the intake vent cover
Note
• The air vents and the intake vent cover should be
cleaned every 100 hours of use. Clean the air vents
and the intake vent cover more often when the pro-
jector is used in a dusty or smoky location.
• Ensure the intake vent cover is securely installed.
The power will not turn on unless it is correctly in-
stalled.
