For more information, call your dealer.
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 
inside of the projector, 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 
 Never unscrew except the appointed (marked by an arrow) screws.
• Do not open the lamp cover while the projector is suspended from 
the ceiling. 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. To replace the 
lamp, make sure that the screws are tightened firmly. Loose screws 
could result in damage or injury.
Use only the lamp of the specifi ed 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 prompt 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 passing the replacement date, could cause it to burst. Do not 
use old (used) lamps; this is a cause of breakage.
