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.
l 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.
l If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  1/2  REPLACE  indicators 
light 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 1/2 REPLACE indicators lighted may increase the risk of lamp explosion.  
l 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 FOLLO wING 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
Maintenance and Care 
						

							64
Turn off the projector, press the Main On/Off Switch to Off 
and unplug the AC power cord from the AC outlet before 
cleaning.
Gently wipe the projection lens with a cleaning cloth that 
contains a small amount of non-abrasive camera lens 
cleaner, or use a lens cleaning paper or 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 of the lens.
Cleaning the Projector Cabinet
Turn off the projector, press the Main On/Off Switch to Off 
and unplug the AC power cord from the AC outlet before 
cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet 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 of the cabinet.
When the projector is not in use, put the projector in 
an appropriate carrying case to protect it from dust and 
scratches.

The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING TEMP. indicator and the LAMP indicator to take proper maintenance. 
Warning Indicators
The projector is shut down and the WARNING TEMP. 
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 LAMP indicator 
turns red brighter and the WARNING TEMP indicator 
blinks 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.
✔Note:
• The WARNING TEMP. indicator continues to blink even after the 
temperature inside the projector returns to normal. When the projector 
is turned on again, the WARNING TEMP. 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? Replace the filter with a new one.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE 
OR ELECTRIC SHOCK.

Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
1. Make sure you have properly connected the projector to peripheral equipment as described \
on pages 20–21.
2.  Check the cable connection. Make sure that all computers, video equipment, and power cords are properly 
connected.
3.  Make sure that all power is switched on.
4.  If the projector still does not produce an image, restart your computer.
5.  If an image still does not appear, disconnect the projector from your computer and check your computer 
monitor’s display. A problem may be noticed with your graphics controller rather than with the projector. 
(When you reconnect the projector, be sure to turn the computer and monitor off before you turn on the 
projector. Turn on equipment in the order of the projector and computer.)
6.  If a problem still persists, check the following solutions.
