Maintaining the Projector

Warning: Before you clean any part of the projector, turn it off and
unplug the cord. Never open any cover on the projector, except the
lamp cover. Dangerous electrical voltages in the projector can injure
you severely. Do not try to service this product yourself, except as
specifically explained here or in the User's Guide. Refer all other
servicing to qualified service personnel.

Cleaning the Lens

Clean the lens whenever you notice dirt or dust on the surface.
❏ Use a canister of compressed air to remove dust.
❏ To remove dirt or smears on the lens, use a commercially
available cloth for cleaning glasses.
Caution: Do not spray liquid or glass cleaner directly on the lens.

Cleaning the Projector Case

Before you clean the case, turn off the projector and unplug the
power cord.
❏ To remove dirt or dust, wipe the case with a soft, dry,
lint-free cloth.
❏ To remove stubborn dirt or stains, wipe the case with a soft
cloth moistened with water and a mild detergent.
Caution: Do not use wax, alcohol, benzene, paint thinner, or other
chemical detergents. These can damage the case.

Cleaning the Air Filter and Vent

Your projector includes an air filter to ensure the best
performance and protect your investment. If dust collects on
the air filter (on the bottom of the projector) or vent (on the
front of the projector), clean them as described below. Dust
clogs prevent proper ventilation and can cause overheating,
which can damage the projector.
Follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the intake vent and filter, use a small vacuum
cleaner designed for computers and other office equipment.
If you don't have one, gently clean the vent with a soft
brush (such as an artist's paintbrush).
