Air Filter prevents dust from accumulating on surface of Projection Lens and Projection Mirror. Should Air Filter become
clogged with dust particles, it will reduce Cooling Fans’ effectiveness and may result in internal heat build up and adversely
affect life of a projector. Clean Air Filter following steps below:
Clean Air Filter with a brush or wash out dust and particles.
3
Replace Air Filter properly. Make sure that Air Filter is fully
inserted.

CAUTION
Do not operate a projector with Air Filter removed. Dust
may accumulate on LCD Panel and Projection Mirror
degrading picture quality.
Do not put small parts into Air Intake Vents. It may result
in malfunction of a projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when operating a projector. Usage in these environments
may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements
inside a projector. This condition may degrade quality of a projected image.
When above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
