Projector Status Lights
The lights on top of the projector indicate the projector’s status
and let you know when a problem occurs.
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 lens-cleaning
paper. If necessary, moisten a soft cloth with lens cleaner and
gently wipe the lens surface.
Caution
Do not use glass cleaner to clean the lens.
Cleaning the Projector Case
Before you clean the case, first 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, moisten a soft cloth with
water and a mild detergent. Then wipe the case.
❏ Do not use wax, alcohol, benzene, paint thinner, or other
chemical detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter on the bottom of the projector after every
100 hours of use. If it is not cleaned periodically, it can become
clogged with dust, preventing proper ventilation. This can cause
overheating and damage the projector. When the filter is
clogged, the projector displays the message “The projector is
overheated.”
To clean the air filter, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the
power cord.
