Air filters help prevent dust from accumulating on the optical elements inside the projector. To whatever extent
the air filters become clogged with dust particles, the cooling fans’ effectiveness is reduced, which may result in
an internal heat build-up and adversely affect the life of the projector. Therefore, for appropriate care and use of
the projector, regular cleaning of the air filters is necessary.
How often the air filters should be cleaned really depends upon the environment in which the projector is being
operated. As a rough guide, under a normally clean operating environment, the air filters should be cleaned
approximately every 200 hours of use. However, if the projector is being operated in a somewhat dusty or
smoky environment, the air filters should be cleaned more often; for consistently good projector operation and
performance, timely cleaning of the air filters is a very important factor. When appropriate, clean the air filters
following the steps below.
Clean the air filters with a brush or rinse them softly. When
rinsing the air filters, dry them well.
3
Replace the air filters properly. Make sure that the air filters
are fully inserted to the projector.

CAUTION
Do not operate the projector with the air filters
removed. Dust may accumulate on the LCD Panel and
projection mirror degrading the picture quality. Do not
put anything into the air intake vents. It may result in
malfunction of the projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when operating the projector. Usage in these environments
may cause a poor image quality.
When using the projector under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical
elements inside the projector. Such condition may degrade the quality of the projected image.
When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.

Turn off the projector and unplug the AC power cord from an AC outlet.
NOTE: If the dust cannot be removed by
cleaning, it is probably time to replace
the air filters with new ones. Please
consult your dealer.
