Warning
Before cleaning any part of the projector, turn it off and unplug the power cord. Never open any cover on
the projector, except as specifically explained in this manual. Dangerous electrical  voltages in the projector
can injure you severely.
Cleaning the air filter
Clean the air filter if dust has a ccumulated on the air filter or when  the following message is displayed.
"The projector is overheating. Make  sure nothing is blocking the air vent, and clean or replace the air
filter."

Since the air filter is removable, you can clean both  sides. Do not rinse the air filter in water. Do not
use detergents or solvents.
Attention
•If dust collects on the air filter, it  can cause the internal temperature of  the projector to rise, and this can lead
to problems with operation and shorten the optical engi ne's service life. Clean them frequently if you are
using the projector in a part icularly dusty environment.
•Do not use an air duster. Combustible substances may  remain, and dust may enter the precision components.
