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, 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. WARNING
• Please reset the lamp time only when you have replaced the lamp, 
for a suitable indication about the lamp. NOTE
• If the lamp should break (it will male a loud bang when it does), unplug the 
power cord from the outlet, and make sure to request a replacement lamp from 
your 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 male 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 for 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) screw.
• Do not open the lamp cover while the projector is suspended from a ceiling 
or somewhere over your head. 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 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.
