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

1	Ventilation Slots of a projector may be blocked. In such an event, reposition a projector so that Ventilation Slots are

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

1	Turn off a projector, and disconnect AC power cord from AC
	outlet.

Do not operate a 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 a projector.
