THE LAMP
HIGH VOLTAGE
HIGH TEMPERATURE
HIGH PRESSURE
Before replacing the lamp, check the serial number of the replacement la\
mp bulb (sold separately)
then contact your local dealer. Before replacing the lamp, turn off the \
power, and unplug the power
cord, then wait at least 45 minutes, in order to ensure that the lamp is\
 properly cooled.
Removing the lamp bulb while it is still hot could cause burns, or cause\
 the lamp bulb to burst.
The LCD projector uses a glass lamp bulb. It is a mercury lamp with high\
internal pressure. High-pressure mercury lamps can break with a loud
bang, or burn out, if jolted or scratched, or through wear over time. Ea\
ch 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 fl\
y into the lamp housing,
and for gas containing mercury to escape from the projector ’s vent holes.
•  Handle with care: jolting or scratching could cause the lamp bulb to bur\
st during use.
• If the replace lamp indicator (see Related Messages (Vol.2       ) \
and Regarding the
indicator Lamps (Vol.2       )) comes on, replace the lamp as soon a\
s 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.
• 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.
• If the lamp should break (it will make a loud bang when it does), vent\
ilate the room well, and make
sure not to breathe the gas that comes out of the projector vents, or ge\
t it in your eyes or mouth.
• If the lamp should break (it will make a loud bang when it does), unpl\
ug 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.
•  Obey local ordinances when disposing of used lamps. In most cases, it is\
 possible to dispose of used
bulbs in the same manner as used glass bottles, but in some cases, bulbs\
 are sorted separately.
• Do not use the projector with the lamp cover removed.

ace the lamp when you power up
