Replacing the lamp
A lamp has finite product life. Using the lamp for long periods of time could cause 
the pictures darker or the color tone poor. Each lamp has a different lifetime, and 
some may burst or burn out soon after you start using them. 
New lamp preparation and early replacement are recommended. To prepare a 
new lamp,  contact your dealer and indicate the lamp type number.
 
Type number :  DT01911

Lamp warning
 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, if the bulb bursts, shards of glass 
can fly into the lamp housing, and gas containing mercury and dust containing fine 
particles of glass can 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  breaks  (it  will  make  a  loud  bang),  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  do  not  try  to  clean  the projector or replace the lamp yourself.• If  the  lamp  should  break  (it  will  make  a  loud  bang),  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  20  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,  because  if  the  lamp’s  bulb  has  broken,  the shards will  fall out when  the cover is opened.  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,  there  may  be 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 to darken, not to light up or to burst. When the pictures appear dark, or when the color tone is poor,  replace the lamp as soon as possible. Do not use old (used) lamps; this is a cause breakage.
