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, make contact with your dealer and tell the following type
