Maintenance and Cleaning

Cleaning the Air Filters

Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the 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 the air filters following the steps below.

1	Turn off the projector, and disconnect the AC power cord from
	the AC outlet.
2	Turn the projector upside down and remove the air filters by
	pulling the latches upward.
3	Clean the air filters with a brush or rinse them softly.
4	When cleaning the air filters by rinsing, dry them well. Replace
	the air filters properly. Make sure that the air filters are fully

inserted.

CAUTION

Do not operate the projector with the air filters 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.

RECOMMENDATION

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 a lens, LCD 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 the Projection Lens

Follow these steps to clean the projection lens.

1	Disconnect the AC power cord before cleaning.
2	Softly wipe the projection lens with a cleaning cloth that con-
	tains a small amount of non-abrasive camera lens cleaner, or use
	lens cleaning paper or a commercially available air blower to
	clean the lens. Avoid using an excessive amount of cleaner.
	Abrasive cleaners, solvents, or other harsh chemicals might
	scratch the surface.
3	When the projector is not in use, replace the lens cover.

Cleaning the Projector Cabinet

Follow these steps to clean the projector cabinet.

1	Disconnect the AC power cord before cleaning.
2	Softly wipe the projector body with a soft, dry cleaning cloth.
	When it is heavily soiled, use a small amount of mild detergent
	and finish with a soft, dry cleaning cloth. Avoid using an
	excessive amount of cleaner. Abrasive cleaners, solvents, or
	other harsh chemicals might scratch the surface.
3	When the projector is not in use, put the projector in the carry-
	ing case to protect it from dust and scratches.
