Cleaning the Air Filter

Clean the air filter and the air intake vent 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."

Attention

• Dust collecting on the air filter may cause the internal temperature of the

projector to rise, leading to a malfunction or early deterioration of optical

parts. Clean the air filter immediately when the message is displayed.

• Do not rinse the air filter in water. Do not use detergents or solvents.

• If a message is frequently displayed, even after cleaning, it is time to

replace the air filter. Replace it with a new air filter.

s "Replacing the Air Filter" p.142

• It is recommended that you clean these parts at least once every

three months. Clean them more often than this if using the projector

in a particularly dusty environment.
