MAINTENANCE

WARNING TEMP. INDICATOR

WARNING TEMP. Indicator flashes red when an internal temperature of a projector exceeds the normal temperature. This Indicator stops flashing when the temperature of a projector returns to normal.

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 Filter prevents dust from accumulating on the 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 the life of the projector. Clean Air Filter 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 Air Filter by pulling

 

the latches upward.

3

Clean Air Filter with a brush or wash out dust and particles.

4

Replace Air Filter properly. Make sure that Air Filter is 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 the 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.

CLEANING PROJECTION LENS

Follow these steps to clean 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.

3

Lightly wipe a cleaning cloth over Projection Lens.

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