Lamp information
Use and replacement of the lamp
When the Lamp Indicator lights up red or a message appears suggesting it is time to replace 
the lamp, please install a new lamp. An old lamp may cause a malfunction in the projector 
and in some instances the lamp may explode.
For more detailed information on the warning indicators, please refer to page 46.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too
hot. Turn the power off, allow the projector to cool down before checking that the dust filters
are not clogged (page 42). If the Lamp or Temp indicator still lights up after turning the power
back on, please contact your dealer.
The following Lamp warning displays will remind you of the lamp condition.
Lamp replacement
• 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 lamp contains mercury. Consult your local hazardous waste regulations and 
dispose of this lamp in the proper manner.
Step 1. Turn the power off and disconnect the projector from the wall socket.
Step 2. Protect the projectors surface by clearing a flat open area on your desk and placing a 
soft item on the desk for padding.
Step 3. 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 4. Loosen the screw that fixes the lamp to the 
projector. If the screw is not loosened 
completely, the lamp cannot be removed. 
Be careful not to lose the screw as it is 
needed to hold the replacement lamp in 
place. It is strongly recommended that you 
use a magnetic-head screwdriver.
Step 5. Lift the handle so that it stands up. Use the 
handle to slowly pull the lamp out of the 
projector.
• Pulling 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.
Step 6. Insert the new lamp. Ensure the handle is fully laid flat and locked in place. Reinsert 
and tighten the screw firmly.
• A Loose screw may cause a bad connection, which could result in malfunction.
• Do not over tighten the screw.
Step 7. Re-install the lamp cover and tighten the 
screws.
Step 8. Make connection to a signal source to be 
displayed. Start up the projector. (Refer to 
page 22 for making connection and page 25 
for turning the power on.)
• Do not turn the power on with the lamp cover 
removed. Whenever the lamp is replaced, 
reset the total lamp operation timer.
