AIR FILTER CARE AND CLEANING

Removable Air Filters prevent dust from accumulating on the surface of Projection Lens and Projection Mirror. Should Air Filters become clogged with dust particles, it will reduce Cooling Fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. Clean Air Filters following the steps below:

1

Turn off the projector, and disconnect AC power cord from the

 

AC outlet.

2

Turn the projector upside down and remove two Air Filters

 

(Large and Small) by pulling the latches upward.

Clean Air Filters with a brush or wash out dust and particles.

4

Replace each Air Filter properly. Make sure that Air Filters are

 

fully inserted.

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 the projector. This condition may degrade the quality of a projected image.

When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.

CLEANING PROJECTION LENS

Follow these steps to clean Projection Lens:

1

Apply a non-abrasive camera lens cleaner to a soft, dry cleaning cloth. Avoid using an excessive amount of cleaner.

 

Abrasive cleaners, solvents or other harsh chemicals might scratch a surface.
