emit a red light
When the temperature inside the projector reaches a
certain level, the projector is automatically shut down to
avoid overheating. The POWER indicator is blinking while
the projector is being cooled down. When the projector has
cooled down enough (to its normal operating temperature),
it can be turned on again by pressing the POWER ON/
STAND-BY button.
PNote:
The WARNING indicator continues to blink even after the
temperature inside the projector returns to normal. When
the projector is turned on again, the WARNING indicator
stops blinking.
Then check the matters below:
– Did you provide appropriate space for the projector to
be ventilated? Check the installing condition to see if
ventilation slots are not blocked.
– Has the projector been installed near an Air-Conditioning/
Heating Duct or Vent? Move the installation of the
projector away from the duct or vent.
– Are the air filters clean? Clean the air filters periodically.
(p.52)
The projector is shut down and the WARNING
indicator lights red.
When the projector detects an abnormal condition, it is
automatically shut down to protect the inside of the projector
and the WARNING indicator lights red. In this case,
unplug the AC power cord and plug it, and then turn on
the projector once again to verify operation. If the projector
cannot be turned on and the WARNING indicator lights red,
unplug the AC power cord and contact the service station.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE
AC POWER CORD CONNECTED UNDER AN
ABNORMAL CONDITION. IT MAY RESULT IN FIRE
OR ELECTRIC SHOCK.

Maintenance and Cleaning
Cleaning the Air Filters
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, they will reduce cooling fans’ effectiveness and may result in a
buildup of internal heat and adversely affect the life of the projector. Clean the air filters by following the steps
below.
1
Turn off the projector, and unplug the AC power cord
from the AC outlet.
2
Turn over the 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.
CAUTION
Do not operate the projector with the air filters
removed. Dust may accumulate on the optical
elements degrading picture quality. Do not put
anything into the air intake vents. Otherwise it may
result in malfunction of the projector.
Air filters
Pull up and remove.
PNote:
When reinserting the air filters, be sure that
the slit part is facing the outer side.
RECOMMENDATION
We recommend avoiding dusty/smoky environments
when you operate the projector. Usage in these
environments may cause poor image quality.
When you use the projector under dusty or smoky
conditions, dust may accumulate on the lens, LCD panels,
or optical elements inside the projector degrading the
quality of a projected image.
When the symptoms above are noticed, contact your
authorized dealer or service station for proper cleaning.

Cleaning the Projection Lens
CAUTION
This projector is equipped with a plastic lens.
Do not rub the lens with a hard fiber cloth or hit it with something hard to prevent the lens from scratching.
Do not use a chemical cleaner (liquid and solid) to avoid deteriorating the lens.
Unplug the AC power cord before cleaning.
First, remove the dust with a blower. Then gently wipe the
lens surface. Use a lens cleaning paper moistened with
methyl alcohol (methanol). Avoid excessive use of cleaner.
Do not use abrasive cleaners, solvents, or other harsh
chemical cleaners to avoid damages the lens.
When the projector is not in use, replace the lens cover.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning
cloth. When it is heavily soiled, use a small amount of mild

LAMP HANDLING PRECAUTIONS
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 life may differ from lamp to lamp and according to the environment of use. There is no guarantee
of the same life for each lamp. Some lamps may fail or terminate their life 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 it
comes to the end of life. 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.
