AIR FILTER CARE AND CLEANING

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 Cooling Fans’ effectiveness and may result in internal heat build up and adversely affect the life of the projector. Clean the Air Filter 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 the Air Filter by

 

pulling the latches upward.

3

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

4

Replace the Air Filter properly. Make sure that the Air Filter is

 

fully inserted.

CAUTION

Do not operate the projector with the Air Filter removed. Dust may accumulate on the LCD Panel 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.

AIR FILTER

Pull up and remove.

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 the 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.

2

3

Lightly wipe a cleaning cloth over the Projection Lens.

When the projector is not in use, replace the Lens Cover.
