Air filters prevent dust from accumulating on the optical elements inside the projector. Should the air filters
become clogged with dust particles, it reduces cooling fans’ effectiveness and may result in internal heat build
up and adversely affect the life of the projector. Clean the air filters following the steps below.
Clean the air filters with a brush or rinse them softly.

CAUTION
Do not operate the projector with the air filters
removed. Dust may accumulate on the optical
elements degrading picture quality.
Do not put small parts 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 poor image quality.
When using the projector under dusty or smoky conditions,
dust may accumulate on a lens, LCD panels, or optical
elements inside the projector. This condition may degrade
the quality of a projected image.
When the symptoms above are noticed, contact your
authorized dealer or service station for proper cleaning.
