 WARNINGHIGH VOLTAGEHIGH TEMPERATUREHIGH PRESSURE
►The  projector  uses  a  high-pressure  mercury  glass  lamp.  The  lamp  can break 
with  a  loud  bang,  or  burn  outwith  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  glassshards  of  glass  to  fl y  into  the  lamp  housing,  and  for gas  containing gas  containing mercurymercury to escape from the projector’s vent holes.
►About disposal of a lamp • This product contains a mercury lamp; do not 
put in trash. Dispose of in accord 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 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 above.  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 specifi ed 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.•  If  the  indicators  or  a  message  prompts  you  to  replace  the  lamp  (see the  section  "Related  Messages"  and  "Regarding  the  indicator  Lamps"), replace  the  lamp  as  soon  as  possible.  Using  the  lamp  for  long  periods 
of  time,  or  past  the  replacement  date,  could  cause  it  to  burst.  Do  not use old (used) lamps; this is a cause of breakage.
