Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should
the air filters become clogged with dust particles, they will reduce cooling fans’ effectiveness and may result in
a buildup of internal heat and adversely affect the life of the projector. Clean the air filters by 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. 4
CAUTION
Do not operate the projector with the air filters
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 using 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 reinserting the air filters, be sure that the
slit part is facing the outer side.
