AIR FILTERS CARE AND CLEANING

Air filters help prevent dust from accumulating on the optical elements inside the projector. To whatever extent the air filters become clogged with dust particles, the cooling fans’ effectiveness is reduced, which may result in an internal heat build-up and adversely affect the life of the projector. Therefore, for appropriate care and use of the projector, regular cleaning of the air filters is necessary.

How often the air filters should be cleaned really depends upon the environment in which the projector is being operated. As a rough guide, under a normally clean operating environment, the air filters should be cleaned approximately every 200 hours of use. However, if the projector is being operated in a somewhat dusty or smoky environment, the air filters should be cleaned more often; for consistently good projector operation and performance, timely cleaning of the air filters is a very important factor. When appropriate, clean the air filters following the steps below.

1

Turn off the projector and unplug the AC power cord from an

 

 

 

AC outlet.

2

Turn over projector and remove the air filters by pulling the

 

 

 

latches upward.

3

Clean the air filters with a brush or rinse them softly. When

 

 

 

rinsing the air filters, dry them well.

4

Replace the air filters properly. Make sure that the air filters

 

 

 

are fully inserted to the projector.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CAUTION

 

 

 

 

 

 

Do not operate the projector with the air filters

 

 

 

 

 

 

 

removed. Dust may accumulate on the LCD Panel and

 

 

 

 

 

 

 

projection mirror degrading the picture quality. Do not

 

 

 

 

 

 

 

put anything into the air intake vents. It may result in

 

 

 

 

 

 

 

malfunction of the projector.

We recommend avoiding dusty/smoky environments when operating the projector. Usage in these environments may cause a poor image quality.

When using the projector under dusty or smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside the projector. Such condition may degrade the quality of the projected image.

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

CLEANING PROJECTION LENS

Follow these steps to clean the projection lens:

1

Turn off the projector and unplug the AC power cord from an AC outlet.

2

Apply a non-abrasive camera lens cleaner to a dry soft cleaning cloth. Avoid using an excessive amount of cleaner.

 

Abrasive cleaners, solvents ,or other harsh chemicals might scratch the surface of the lens.

3

4

Gently wipe with the cleaning cloth over the projection lens.

When the projector is not in use, put the lens cap.
