Replacing the lamp
A lamp has fi nite product life. Using the lamp for long periods of time could cause 
the pictures darker or the color tone poor. Note that each lamp has a different 
lifetime, and some may burst or burn out soon after you start using them.
Preparation of a new lamp and early replacement are recommended. To prepare 
a new lamp, make contact with your dealer and tell the lamp type number.
Type number : 003-120730-01  
(DT01175) 
1. Turn the projector off, and unplug the power cord. 
Allow the projector to cool for at least 45 minutes.
2. Prepare a new lamp. If the projector is mounted on 
a ceiling, or if the lamp has broken, also ask the 
dealer to replace the lamp.
In case of replacement by yourself, follow the following 
procedure.
3. Loosen the screw (marked by arrow) of the lamp 
cover and then slide and lift the lamp cover to the 
side to remove it.
4. Loosen the 3 screws (marked by arrow) of the 
lamp, and slowly pick up the lamp by the handles. 
Never loosen any other screws.
5. Insert the new lamp, and retighten fi rmly the 
3 screws of the lamp that are loosened in the 
previous process to lock it in place.
6. While putting the interlocking parts of the lamp 
cover and the projector together, slide the lamp 
cover back in place. Then fi rmly fasten the screw 
of the lamp cover.
7. Turn the projector on and reset the lamp time 
using the LAMP TIME item in the OPTION menu.

 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, if the 
bulb bursts, it is possible for shards of glass to fly into the lamp housing, and 
for gas containing mercury and dust containing fine particles of glass 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, consult your local government agency  
or www.eiae.org (in the US) or www.epsc.ca (in Canada).
For more information, ask 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 inhale the gas or fine 
particles that come out from the projector's vent holes, and not to get 
them into 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 sufficiently. 
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 
a ceiling. 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. Use of a lamp that does not 
meet the lamp specifications for this model could cause a fire, damage or 
shorten the life of this product.
• 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, consult 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.
