THE LAMP
HIGH VOLTAGE 
HIGH TEMPERATURE
HIGH PRESSURE
Before replacing the lamp, check the serial number of the replacement la\
mp bulb (sold separately:
DT00521), then contact your local dealer. Before replacing
the lamp, turn off the power, and unplug the power cord, then wait at le\
ast 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.

es, and switch power ON again. If the LAMP indicator is still red, replace the lamp.NOTE
THE LAMP (continued)
Replacing the lamp
All projector lamps will wear out eventually. If used for long periods o\
f time, the image could become 
darkened, and the color contrast could be impacted as well. We recommend\
 that you replace your lamps
early. If the LAMP indicator turns red, or a message prompts you to repl\
ace the lamp when you power up
the projector, the lamp needs to be replaced. (See Related Messages (\
Vol.2      ) and Regarding the
Indicator Lamps (Vol.2        ) for details.)

ATTENTION• Make sure that the screws are screwed in firmly. Loose screws could resu\
lt in damage or injury.
• Do not use with lamp cover removed.
•
Do not reset the lamp timer without replacing the lamp. Reset the lamp t\
imer always when replacing 
the lamp. The message functions will not operate  properly if the lamp t\
imer is not reset correctly.
