Note:
When reinserting these filters, be sure
that the slit part is facing the outer side.
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters 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, clean the filters
immediately. Clean the filters by following the steps below.
CAUTION
Do not operate the projector with the filters
removed. Dust may accumulate on the optical
elements degrading picture quality.

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 a 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.
