Lamp Information
Warning Message
When the Lamp indicator lights up red or a message appears suggesting it is time to 
replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a 
malfunction in the projector and in some instances the lamp may break.
For more detailed information on lamp warnings, please refer to page 35.
• The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp 
indicator still lights up after turning the power back on, please contact your dealer.
• Do not remove the lamp immediately after using the projector.  You may get burned because 
the lamp is very hot after use.
• Before replacing the lamp, press the POWER button to turn off the lamp and wait for two 
minutes for the lamp to cool down. Unplug the power cord from the wall outlet and wait one 
hour for the lamp to cool down completely. 
• Do not remove the lamp except for replacement. Careless handling can cause injury or fire.
• Do not touch the lamp directly. It may break and cause injury or burn.
• Be sure not to drop the lamp lid screw into the projector. Also be sure not to put metal or any 
flammable objects inside because it may cause fire or electric shock. If any objects should fall 
inside, unplug and contact your dealer.
• Install the lamp securely to prevent failure and fire.
• If the lamp should break, small glass fragments may fall out through the grilles and some may 
remain inside of the projector or the lamp box. When taking the lamp box out, be sure to turn 
over the projector and hold the handle of the lamp box to avoid injury due to the glass 
fragments.
• If the lamp should break, never shake the lamp box or hold it in front of your face after 
removing it. The glass fragments may fall out and cause injury to your eyes.
• When placing the projector upside down to replace the lamp or conduct maintenance, ensure 
that the projector is securely placed before working with it.
• The lamp is fragile. If it is broken, be careful not to cut yourself with glass fragments.
• Contact your dealer for a new lamp.
Interval of lamp replacement
The recommended interval of lamp replacement is about 2000 hours*1 of consecutive use. 
Such interval differs depending on the operating environment and may be shorter than 2000 
hours

be replaced. When the lamp operation time exceeds 1500 hours*1, the lamp replacement 
message will appear on the screen for 30 seconds*3 every time the lamp is turned on. When 
the lamp has been used for about 2000 hours*1,*2, the replacement message will flash in the 
center of the screen for 30 seconds*3 . (In such cases, the LAMP indicator lighting up red.) 
The projector will shutdown after one minute. 
*1  When Mode of the Picture menu is not set to Lamp Low mode continuously. When it is 
set to Lamp Low mode, this duration will be extented.
*2  When Mode is set to Lamp Low mode, this duration  will be extented to 2500 hours.

							Maintenance 33
Replacing the Lamp
• To reduce the risk of electrical shock, always turn the projector off and disconnect the power 
cord before changing the lamp.   
• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before 
replacing the lamp.
• To reduce the risk of injuries to fingers and damage to internal components, use caution when 
removing lamp glass that has shattered into sharp pieces.
• To reduce the risk of injuries to fingers and/or compromising image quality by touching the 
lens, do not touch the empty lamp compartment when the lamp is removed.
• This projector uses a lamp that contains mercury. Disposal of the lamp or the projector with 
the lamp may be regulated due to environmental considerations. For disposal or recycling 
information, please contact your local authorities or the Electronic Industries Alliance: 
www.eiae.org. (For US only).
Step 1. Turn the power off and disconnect the projector from the wall socket.
Step 2. Turn the projector over. Then loosen the 
screws and remove the lamp cover. If 
the lamp is hot, avoid burns by waiting 
for 45 minutes until the lamp has 
cooled.
Step 3. Loosen the screw that holds the lamp to 
the projector. If the screw is not loos-
ened completely, they could injure your 
fingers. It is strongly recommended that 
you use a magnetic-head screwdriver.
Step 4.  Lift the handle so that it stands up. Use 
the handle to slowly pull the lamp out of 
the projector.
Important:
• Pulling it too quickly may cause the lamp to 
break and scatter broken glass in the projector.
• Do not place the lamp in locations where 
water might splash on it, children can reach it, 
or near flammable materials.
• Do not insert your hands into the projector after the lamp is removed. If you touch the 
optical components inside, it could cause color unevenness and distortion of the projected 
images. 
						

							Maintenance 34Step 5. Insert a new lamp. Make sure the handle is fully locked and tighten the screw firmly.
Important:
• Loose screw may cause a bad connection, which could result in malfunction.
• Do not over tighten the screw.
Step 6. Re-install the lamp cover and tighten the screw. Do not turn the power on with the 
lamp cover removed. Whenever the lamp is replaced, reset the total lamp operation 
time. Do not reset if the lamp is not replaced as this could cause damage. 
Resetting the lamp counter
If replacing the lamp after 2000 hours of operation, please carry out the following operation 
within one minute of powering on. (When the replacement message appears, the projector

onds to display the total used lamp time.
