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,  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.
• 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 inside of the projector, 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 the  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. To replace the lamp,  make  sure  that  the  screws  are  tightened  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
