The removable Air filter prevents dust from accumulating on the surface of the projection lens and projection mirror. Should
the Air filter 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 filter by following the steps below.
Clean the Air filter with a brush or wash out dust and particles.

Replace the Air filter properly. Make sure that it is fully inserted.

CAUTION
Do not operate the projector with the Air filter removed.
Dust may accumulate on the LCD panels and the projection
mirror degrading picture quality.
Do not put small parts into the Air intake vents. It may result
in malfunction of the projector.
Operating Environment
We recommend avoiding dusty/smoky environments when operating a projector.
When using under dusty or smoky conditions, dust may accumulate on the lens, liquid crystal panels, or optical elements
inside the projector. This condition may degrade the quality of a projected image and the life of the projector.
When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
