A lamp has finite 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.

cover and then slide and lift the lamp cover to the 
side to remove it.
4.Loosen the 2 screws (marked by arrow) of the lamp, 
and slowly pick up the lamp by the handles.

Lamp warning
Replacing the lamp (continued)
 HIGH VOLTAGE  HIGH TEMPERATURE HIGH PRESSURE
►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, consult your local government agency  
or www.eiae.org (in the US) or www.epsc.ca (in Canada).
For more information, call your dealer.WARNING
• 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 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.
• 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.

internal temperatures rise and could cause a fire, a burn or malfunction to the projector.
NOTE  • Please reset the filter time only when you have cleaned or replaced 
the air filter, for a suitable indication about the air filter.
• The projector may display the message such as the “CHECK THE AIR FLOW” 
or turn off the projector, to prevent the internal heat level rising.
