Lamp warning
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, contact 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, contact your local dealer or a service representative.• Handle with care: jolting or scratching could cause the lamp bulb to bur st 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. 
Disconnect the plug from the power outlet

Maintenance
Please check and clean the air filter periodically. If the air filter becomes clogged 
by dust or the like, internal temperatures rise, which could cause a fire, a burn or 
malfunction to the projector. When the indicators or a message prompts you to 
clean the air filter, comply with it as soon as possible. Note that the projector may 
shut down, when the projector heats too much.
Please replace the air filter when it is damaged or too soiled. Preparation of a new 
air filter is recommended. To prepare a new air filter, contact with your dealer and 
tell the air filter type number.

of specified type will come together with a replacement lamp for this projector .
• 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 “CHECK THE AIR FLOW” or 
turn off the projector, to prevent the internal heat level rising.
NOTE
►Before taking care of the air filter, make sure the power switch 
is off and the power cable is not plugged in, then allow the projector to cool 
sufficiently. Taking care of the air filter in a high temperature state of the projector
