Cleaning the lter
The lter prevents dust from accumulating on the surface of lens assembly. Should the lter become
clogged with dust particles, it will reduce the cooling fan’s effectiveness and may result in internal heat
buildup and adversely affect the life of the projector. If a Filter warning icon appears on the screen, you
should clean the lter immediately. To do that, follow the steps below:
1 Turn off the projector, and unplug the AC power
cord from the AC outlet.
2 Release the two hooks and remove the air lter.
3 Gently clean the lter with a brush.
4 Reinstall the lter into the projector properly.
Ensure that a clicking sound is heard to conrm
the lter is completely installed.
Note:
Do not operate the projector when the
lter is removed. Otherwise, dust will be
accumulated on lens and thus affect the
image quality.
Never attempt to place any objects to the
air intake vents. Otherwise, the projector
may malfunction.
