Lamp war ning
Replacing the lamp (continued)
 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, if the bulb bursts, it is possible 
for shards of glass to fly into the lamp housing, and for gas containing mercury and 
dust containing fine particles of glass 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, consult your local government agency  
or www.eiae.org (in the US) or www.epsc.ca (in Canada).
For more information, call your dealer.WARNING
• 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 inhale the gas or fine particles that come out 
from the projectors vent holes, and not to get them into 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. Use of a lamp that does not 
meet the lamp specifications for this model could cause a fire, damage or 
shorten the life of this product.
• 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, consult 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 dark, 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.
