Maintenance and Cleaning
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.
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.

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 center for proper cleaning.
