6-7 Lamp
HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
WARNING
► 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.
• 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 suf fi ciently. 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 fi rmly. Loose screws could result in damage or injury.
• Use only the lamp of the speci fi ed type.
• If the lamp breaks soon after the fi rst 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 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.
