Filter prevents dust from accumulating on the optical elements inside the projector. Should the Filter become
clogged with dust particles, it will reduce cooling fans’ 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, replace the Filter
immediately. Replace the filter by following the steps below.
Loosen the screw and open the lamp cover and lift the
filter out of the projector.

CAUTION
- Do not operate the projector with the filter removed.
Dust may accumulate on the optical elements
degrading picture quality.
- Do not put anything into the air vents. Doing so may
result in malfunction of the projector.
- Do not wash the filter with water or any other liquid
matter. Otherwise the filter may be damaged.
RECOMMENDATION
We recommend avoiding dusty/smoky environments
when you operate the projector. Usage in these
environments may cause poor image quality.
When using the projector under dusty or smoky conditions,
dust may accumulate on a lens 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 center for proper cleaning.
