Cleaning the Filter
The air-lter sponge keeps dust and dirt from getting inside
the projector and should be frequently cleaned. If the lter is
dirty or clogged, your projector may overheat.
The message for lter
cleaning will be dis-
played for one minute
when the projector is
turned on or off.
To cancel the message,
press any button on
the projector cabinet
or the remote control.
CAUTION:
• Turn off the projector, and unplug the projector before replacing the lter.
• Only clean the outside of the lter cover with a vacuum cleaner.
• Do not attempt to operate the projector without the lter cover.
To clean the air-lter
Use a small vacuum cleaner designed for computers and other
ofce equipment.
If the dirt is difcult to remove or the lter is broken, please
contact your local dealer or service center to obtain a new
lter.
