section AIR FILTER CARE AND CLEANING on this page.

If WARNING TEMP. Indicator remains on after performing above checks,

Cooling Fans or Internal Circuits may be malfunctioning. Contact the service

station.

The Warning Temp. Indicator flashes red to let you know the internal temperature

of the projector exceeds the normal level. If the temperature goes up further, the

projector will be turned off automatically and the Ready indicator will go out. (The

Warning Temp. Indicator continues flashing.) After the cooling-off period, the

Ready Indicator lights on again and the projector can be turned on by pressing the

On/Off button on the remote control unit or on the side control. When you turn on

the projector, the Warning Temp. Indicator will go out.

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.

NOTE: If the dust cannot be removed by

cleaning, it is probably time to replace

the air filters with new ones. Please

consult your dealer.

CAUTION

Do not operate the projector with the Air Filter(s) removed.

Mirrors degrading the picture quality.

Do not put anything into the air intake vents. Doing so may

result in a malfunction of the projector.

Failure to properly clean the projector's air filters (in

accordance with the instructions in your Projector's

Operating Manual, or more frequently in any environment

which is somewhat dusty or smoky) could result in

overheating and will void the warranty on the projector.
