WARNING TEMP. INDICATOR

WARNING TEMP. 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 WARNING TEMP. 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 projector 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.

If WARNING TEMP. Indicator remains on after performing the above checks, the Cooling Fans or the Internal

 

Circuits may be malfunctioning. Contact service personnel from an authorized dealer or service station.

AIR FILTER CARE AND CLEANING

The Removable Air Filters prevent dust from accumulating on the surface of the Projection Lens and the Projection Mirror. Should the Air Filters 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 Filters 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 two Air Filters

(Large and Small) by pulling the latches upward.

3

Clean the Air Filters with brush or wash out the dust and

particles.

4

Replace each Air Filter properly. Make sure that the Air Filters

are fully inserted.

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.

The Air Filter is a small part. Ensure that children don’t eat or swallow it.

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.

CLEANING THE PROJECTION LENS

Follow these steps to clean the 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 the lens.

2

3

Lightly wipe the cleaning cloth over the lens.

When the projector is not in use, replace the lens cover.
