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. Note that each lamp has a different 
lifetime, and some may burst or burn out soon after you start using them. 
Preparation of a new lamp and early replacement are recommended. To prepare 
a new lamp, contact to your dealer and tell the lamp type number.
Type number : 456-8755H
. Turn the projector off, and unplug the power cord. 
Allow the projector to cool for at least 45 minutes.
2. Prepare a new lamp. If the projector is mounted 
on a ceiling, or if the lamp has broken, also ask 
the dealer to replace the lamp.
In case of replacement by yourself, follow the following 
procedure.
3. Loosen the screw (marked by arrow) of the lamp 
cover and then slide the lamp cover to the side to 
remove it.
4. Loosen the 2 screws (marked by arrow) of the 
lamp, and slowly pick up the lamp by the handles. 
5. Insert the new lamp, and retighten firmly the 
2 screws of the lamp that are loosened in the 
previous process to lock it in place. 
6. Slide the lamp cover back in place and firmly 
fasten the screw of the lamp cover.

 HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
WARNING  ►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, contact to 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 
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 to 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
