WARNING
 
 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 con-
taining 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. Dis-
pose 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.
