may cause the lamp cover to fall down. If the lamp is broken, pieces of glass may fall and
cause an injury.

wall outlet.
Cleaning the Air Filter
The air filter prevents dust and dirt from entering the interior of the projector. If you will use the projector
in a dusty location, install the air filter.
A buildup of dust on the air filter may cause poor ventilation, causing the interior of the projector
overheat and operations to stop or malfunction. Clean the air filter regularly.
If the message "Check the air filter for dirt." is displayed, check the air filter for dirt or dust, and use the
following procedure to clean off any dirt or dust.
1. Disconnect the power plug.
