We recommend avoiding dusty/smoky environments when operating a projector. Usage in these environments may cause poor image quality and may void the warranty.

When using under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside a projector. This condition may degrade quality of a projected image.

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

CLEANING 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.

Lightly wipe a cleaning cloth over Projection Lens.

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