Wa rn ing Indicator
The projector is shut down and the WARNING
indicator is blinking red.
When the temperature inside the projector reaches a
certain level, the projector will be automatically shut down
to protect the inside of the projector. 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 ON/STAND-BY button.
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 reconnect it, and then
turn the projector on once again to verify operation. If the
projector cannot be turned on and the WARNING indicator
still lights red, unplug the AC power cord and contact the
service station.

✔Note:
• 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 the air
vents of the projector 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.
– Is the filter clean? Clean the filter periodically.

Filter prevents dust from accumulating on the optical elements inside th\
e projector. Should the filter becomes
clogged with dust particles, it will reduce cooling fans’ effectivene\
ss and may result in internal heat buildup and
adversely affect the life of the projector. If a “Filter warning” \
icon appears on the screen, clean the filter
immediately. Clean the filter by following the steps below.
Gently clean the filter by using a brush or rinse it
softly.3
When rinsing the filter, dry it well. Replace the filter
properly. Make sure that the filter is fully inserted to
the projector.4
CAUTION
Do not operate the projector with the filter
removed. Dust may accumulate on the optical
elements degrading picture quality.
Do not put anything into the air vents. Doing so
may result in malfunction of the projector.
RECOMMENDATION We recommend avoiding dusty/smoky environments
when you operate the projector. Usage in these
environments may cause poor image quality.
When using the projector under dusty or smoky conditions,
dust may accumulate on a 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.
✔Note:
• When reinserting this filter, be sure that the slit
part is facing the outer side.

Maintenance and Cleaning
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 haza\
rd.
●Lamp life may differ from lamp to lamp and according to the environment \
of use. There is no guaranteeof the same life for each lamp. Some lamps may fail or terminate their l\
ife in a shorter period of time
than other similar lamps.
●If the projector indicates that the lamp should be replaced, i.e., if th\
e LAMP REPLACE indicator lightsup, replace the lamp with a new one IMMEDIATELY after the projector has \
cooled down.  
(Follow carefully the instructions in the Lamp Replacement section of t\
his manual.) Continuous use of
the lamp with the LAMP REPLACE indicator lighted may increase the risk o\
f lamp explosion.  
●A Lamp may explode as a result of vibration, shock or degradation as a r\
esult of hours of use as itslifetime 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 ou\
tlet 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 a\
round the projector or coming out
from the cooling air circulation holes. Any broken shards found should b\
e 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 u\
nit by anyone, especially those who
are not appropriately trained to do so, may result in an accident or inj\
ury caused by pieces of broken
glass.
