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.
