Projection Mirror. Should the Air Filters become clogged with dust particles, it will reduce the 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 brush or wash out the dust and
particles.

Replace each Air Filter properly. Make sure that the Air Filters
are fully inserted.

CAUTION
Do not operate the projector with the Air Filter removed.
Dust may accumulate on the LCD Panel and the Mirror
degrading picture quality.
Do not put small parts into the Air Intake Vents. It may
result in malfunction of the projector.

or swallow it.

We recommend avoiding dusty/smoky environments when operating the projector. Usage in these
environments may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on the liquid crystal panel, lens, or optical elements
inside it. This condition may degrade the quality of the projected image.
When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
