After the temperature inside the projector returns to normal, the WARNING
indicator still continues to flash.  When the projector is turned on again, the
WARNING indicator stops flashing. 
Then check the items below.
Did you provide appropriate space for the projector to be
ventilated?  Check the installing condition to see if ventilation slots
are not blocked.
Is the projector not installed near the ventilation duct of air-
conditioning equipment which may be hot? Install the projector
away from the ventilation duct of air-conditioning equipment. 
Are the air filters clean?  Clean the air filters periodically.

Air filters prevent dust from accumulating on the surface of the optical elements inside the projector.  Should the air filters
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 the air filters following the steps below.
Clean the air filters with a brush or rinse them softly.3
When cleaning the air filters by rinsing, dry them well.  Replace
the air filters properly. Make sure that the air filters are fully
inserted.4
CAUTION
Do not operate the projector with the air filters removed.
Dust may accumulate on the LCD panel and the projection
mirror degrading picture quality.
Do not put small parts into the air intake vents.  It may
result in malfunction of the projector.
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 a lens, LCD 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 the Air Filters
Cleaning the Projection Lens
Cleaning the Projector Cabinet
Disconnect the AC power cord before cleaning.1
Softly wipe the projector body with a soft, dry cleaning cloth.
When it is heavily soiled, use a small amount of mild detergent
and finish with a soft, dry cleaning cloth.  Avoid using an
excessive amount of cleaner.  Abrasive cleaners, solvents, or
other harsh chemicals might scratch the surface.2
Follow these steps to clean the projector cabinet.
When the projector is not in use, put the projector in the carry-
ing case to protect it from dust and scratches.3
Softly wipe the projection lens with a cleaning cloth that con-
tains a small amount of non-abrasive camera lens cleaner, or use
lens cleaning paper or a commercially available air blower to
clean the lens.  Avoid using an excessive amount of cleaner.
Abrasive cleaners, solvents, or other harsh chemicals might
scratch the surface.

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.  
LAMP HANDLING PRECAUTIONS

NOTE
Do not reset the Lamp replace counter without implementation of lamp
