Maintenance  
Lamp 
WA R N I N G HIGH VOLTAGE
 HIGH TEMPERATURE  HIGH PRESSURE 
►The projector uses a high-pressure mercury glass lamp. The lamp can break with a loud 
bang, or burn out, if jolted or scratched, handled while hot, or worn over time. Note that 
each lamp has a different lifetime, and some may burst or burn out soon after you start 
using them. In addition, when the bulb bursts, it is possible for shards of glass to fly into 
the lamp housing, and for gas containing mercury to escape from the projector’s vent 
holes. 
►About disposal of a lamp    • This product contains a mercury lamp; do not put in 
trash. Dispose of in accord with environmental laws. 
For lamp recycling, go to www.lamprecycle.org. (in the US) 
For product disposal, contact your local government agency or www.eiae.org (in the 
US) or www.epsc.ca (in Canada). 
For more information, call your dealer. 
 
Disconnect 
the plug 
from the 
power outlet 
• If the lamp should break (it will make a loud bang when it does), unplug 
the power cord from the outlet, and make sure to request a replacement 
lamp from your local dealer. Note that shards of glass could damage the 
projector’s internals, or cause injury during handling, so please do not try 
to clean the projector or replace the lamp yourself. 
• If the lamp should break (it will make a loud bang when it does), 
ventilate the room well, and make sure not to breathe the gas that comes 
out of the projector vents, or get it in your eyes or mouth. 
• Before replacing the lamp, turn the projector off and unplug the power cord, then 
wait at least 45 minutes for the lamp to cool sufficiently. Handling the lamp while 
hot can cause burns, as well as damaging the lamp. 
 
• Never unscrew except the appointed (marked by an arrow) screws. 
• Do not open the lamp cover while the projector is suspended from above. 
This is dangerous, since if the lamp’s bulb has broken, the shards will fall out 
when the cover is opened. In addition, working in high places is dangerous, so 
ask your local dealer to have the lamp replaced even if the bulb is not broken. 
• Do not use the projector with the lamp cover removed. At the lamp replacing, 
make sure that the screws are screwed in firmly. Loose screws could result in 
damage or injury. 
 
• Use only the lamp of the specified type. 
• If the lamp breaks soon after the first time it is used, it is possible that 
there are electrical problems elsewhere besides the lamp. If this happens, 
contact your local dealer or a service representative. 
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use. 
• If the indicators or a message prompts you to replace the lamp (see the 
section “Related Messages” and “Regarding the indicator Lamps”), replace the 
lamp as soon as possible. Using the lamp for long periods of time, or past the 
replacement date, could cause it to burst. Do not use old (used) lamps; this is a 
cause of breakage.
