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. Clean the air filter by following the steps
below.
Gently clean the filter by using a brush or blower.

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
anything into the air intake vents. Otherwise it may
result in malfunction of the projector.
RECOMMENDATION
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 degrading the quality of a projected image.
When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.

Note:
• When cleaning the air filter, protect the
infrared remote receiver with a soft cloth to
