Maintenance and Cleaning
Replacing the Filter
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.
1Turn off the projector, and unplug the AC power cord from the AC outlet.
2Put you finger on the latch’s mark, pull it the unlock position and remove.

- Do not operate the projector with the filters 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, 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.
