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 containing mercury to escape from the 
projector’s vent holes.
● About disposal of a lamp: This product contains a mercury lamp; do not put it in a 
trash. Dispose of it in accordance 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 
a 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. 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.
● Using the lamp for long periods of time, could cause it to darken, not 
to light up or to burst. When the pictures appear dark, or when the 
color tone is poor, please replace the lamp as soon as possible. Do not 
use old (used) lamps; this is a cause of breakage.
