WARNING TEMP. INDICATOR

WARNING TEMP. Indicator flashes red and projector is automatically turned off when an internal temperature of the projector exceeds normal temperature. Wait at least 5 minutes before turning on projector again.

When WARNING TEMP. Indicator continues to flash, check the items listed below.

1	Ventilation Slots of the projector may be blocked. In such an event, reposition the projector so that Ventilation Slots
	are not obstructed.
2	Air Filter may be clogged with dust particles. Clean Air Filter by following the section AIR FILTER CARE AND
	CLEANING below.
3	If WARNING TEMP. Indicator remains on after performing the above checks, Cooling Fans or the Internal Circuits may
	be malfunctioning. Contact service personnel from an authorized dealer or a service station.

AIR FILTER CARE AND CLEANING

Removable Air Filters prevents 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 three Air Filters by
	pulling the latches upward.
3	Clean Air Filters with a brush or wash out dust and particles.
4	Replace three Air Filters properly. Make sure that Air Filters are
	fully inserted.

CAUTION

Do not operate the projector with Air Filter removed. Dust may accumulate on LCD Panel and Projection Mirror degrading picture quality.

Do not put small parts into 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.
