To replace the lamp, check the model number of the replacement lamp (so\
ld separately) and
contact your local dealer.
Replacement lamp model number: 78-6969-9601-2
If the projector is mounted on the ceiling, or if the lamp has broken, a\
sk your dealer to replace the
lamp. Lamp replacement is hazardous and should not be attempted by the u\
ser.
Before replacing the lamp, make sure the power switch is off and the pow\
er cable is not plugged in,
then wait at least 45 minutes for the lamp to cool sufficiently. Handlin\
g the lamp while hot can cause
burns, as well as damaging the lamp.
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.
•  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 lo\
cal dealer to have
the lamp replaced even if the bulb is not broken.
•  Handle with care: jolting or scratching could cause the lamp bulb to bur\
st during use.
• If the replace lamp indicator (see Related Messages (      ) and R\
egarding the indicator
Lamps (       )) comes on, replace the lamp as soon as possible. Usi\
ng 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 o\
r a service representative.
• 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.

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 (\
      ) and Regarding the
Indicator Lamps (        ) for details.)
1Turn off the projector, and unplug the
power cord. Allow the lamp bulb to cool
for at least 45 minutes, and prepare a
new lamp.4Insert the new lamp, and
tighten the 3 screws firmly to
lock it in place.
5Interlocking the 2 tabs of the
lamp cover to the projector,
put the lamp cover on the
projector.
Then push the point of the
lamp cover to fix it, as shown
in the figure.
Make sure that the lamp
cover doesn’t come up.
2After making sure that the projector has
cooled adequately, slide the knob of a
lamp cover lock as shown in the figure.
Then, one side of the lamp cover is
raised. Pull up the lamp cover and
remove it, as shown in the figure.
3Unscrew the 3 screws, and slowly pull
out the lamp by the handle.
•  Be careful not to touch the inside of the lamp case.
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.
• When the lamp has been replaced after the message of  “CHANGE THE LAMP .....THE POWER
WILL TURN OFF AFTER 0 hr. ” is displayed, or the LAMP indicator is red, complete the following
operation within 10 minutes of switching power on.

Related Messages
When the units power is ON, messages such as those shown below may be d\
isplayed. When
any such message is displayed on the screen, please respond as described\
 below.
Note 1: Although this message will be automatically disappeared after around 3 m\
inutes, it will be
reappeared every time the power is turned ON.
Note 2: Lamps have a finite product life. Lamps are characterized by the fact th\
at, after long hours of usage, a lamp will no longer light up, or the lamp will break or burst, \
etc. This unit is equipped
with an automatic shut-down function, such that the power will automatic\
ally be turned OFF
when lamp usage time has reached 2,000 hours. Please be aware, however, \
that among lamp
types, there are major differences in product lifetimes; a lamp may thus\
 fail to light even prior
to the functioning of the automatic shut-down function of this unit.
