If WARNING TEMP. Indicator remains on after performing above checks,
Cooling Fans or Internal Circuits may be malfunctioning. Contact the service
station.3
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.
If the Warning Temp. Indicator is still flashing, check the followings; FRONT INDICATORS

remote control unit or on the side control. If this case happenes, disconnect and reconnect the AC power cord, and then turn
on the projector again to check its operation. If the projector shuts down again or fails to be turned on, the internal check and
repair will be required. Plug off the AC power cord and contact service station.

REAR INDICATORS
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.

APPENDIX
This projector uses a high-pressure lamp which must be handled carefully and properly.  Improper
handling may result in accidents, injury, or create a fire hazard.
Lamp lifetime may differ from lamp to lamp and according to the environment of use.  There is no
guarantee of the same lifetime for each lamp.  Some lamps may fail or terminate their lifetime in a
shorter period of time than other similar lamps.
If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE INDICATOR
lights up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down.  
( Follow carefully the instructions in the LAMP REPLACEMENT section of this manual.  )  Continuous
use of the lamp with the LAMP REPLACE INDICATOR lighted may increase the risk of lamp explosion.  
A Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its
lifetime draws to an end.  Risk of explosion may differ according to the environment or conditions in
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately.  Contact an
authorized service station for a checkup of the unit and replacement of the lamp.  Additionally, check
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out
from the cooling air circulation holes.  Any broken shards found should be cleaned up carefully.  No one
should check the inside of the projector except those who are authorized trained technicians and who are
familiar with projector service.  Inappropriate attempts to service the unit by anyone, especially those who
are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken
glass.
