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.

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. 

Clean the air filters and air intake vents after every 100 hours 
of use. If they are not cleaned periodically, they can become 
clogged with dust, preventing proper ventilation. This can 
cause overheating and damage the projector. 

Follow these steps:

1. Turn off the projector. Wait for the 

Power

 light to stop 

flashing, then unplug the power cord.

2. To clean the intake vents, use a small vacuum cleaner 

designed for computers and other office equipment. If you 
don’t have one, gently clean the vents with a soft brush 
(such as an artist’s paintbrush).
