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, if the bulb bursts, it is possible 
for shards of glass to fly into the lamp housing, and for gas containing mercury and 
dust containing fine particles of glass 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  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  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  mounted  on  a  wall 
or  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.  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,  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.
