Maintenance
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.

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,
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 handle.  
It may make it easy to take the lamp out slightly 
toward the control panel of the projector.
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. Tighten the 
screw  first, then screw .
6. Slide the lamp cover back in place and firmly

Lamp warning
 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, 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 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
