Maintenance and cleaning
Cleaning the air filter
The air filter prevents dust from accumulating on the surface of the optical elements inside the projector. Should the
air filter become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in a buildup of
internal heat and adversely affects the life of the projector. If the Filter warning icon appears on the screen, the air
filter should be cleaned immediately. Clean the air filter following the steps below.
1
Turn off the projector, and unplug the AC power cord from the AC outlet.
2
Remove the air filter
3
Gently clean the filter with a brush.
4
Reinstall the filter into the projector properly.
Caution
Do not operate the projector with the air filter removed. Dust may
accumulate on the optical elements, degrading picture quality.
Do not put any small objects into the air intake vents. Otherwise, it
may result in malfunction of the projector.

Resetting the filter counter
Be sure to reset the filter counter after cleaning or
replacing the filter.
We recommend avoiding dusty/smoky
environments when you operate the projector.
Usage in these environments may cause poor
image quality.
When you use the projector under dusty or
smoky conditions, dust may accumulate on the
lens, LCD panels, or optical elements inside the
projector. When the symptoms above are
noticed, contact your authorized dealer or
service station for proper cleaning.
