MAINTENANCETEMPERATURE WARNING INDICATOR

The TEMPERATURE WARNING Indicator flashes red when the internal temperature of the projector exceeds the normal temperature. The Indicator stops flashing when the temperature of the projector returns to normal. When the TEMPERATURE WARNING Indicator continues to flash, check the items listed below.

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

AIR FILTER CARE AND CLEANING

The Removable Air Filter prevents dust from accumulating on the surface of the Projection Lens and the Projection Mirror. Should the Air Filter become clogged with dust particles, it will reduce the 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 the power off, and disconnect the AC power cord from the
	AC outlet.
2	Turn the projector upside down and remove the Air Filter Cover
	by pressing four latches sideways and pulling up. Remove three
	Air Filters by pulling up the latches.
3	Clean the Air Filters with brush or wash out the dust and
	particles. Be sure to dry them out.
4	Replace the Air Filters and Air Filter Cover properly. Make sure
	that they are fully set.

CAUTION

Do not operate the projector with the Air Filter removed. Dust may accumulate on the LCD Panel and the 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 the liquid crystal panel, lens, or optical elements inside it. This condition may degrade the quality of the projected image.

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

Press the latches sideways and pull up.

Remove three Air Filters by pulling up the latches.
