Maintenance
The air lter unit of this projector consists of a lter cover, two kinds of lters, and
a lter frame. The new double large lters system is expected to function longer.
However, please check and clean it periodically to keep ventilation needed for
normal operation of the projector.
When the indicators or a message prompts you to clean the air lter, comply with
it as soon as possible. Replace the lters when they are damaged or too soiled.
To prepare new lters, contact to your dealer and tell the following type number.
