    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, make contact with your dealer and tell the lamp type number .

    cover and then slide and lift the lamp cover to the 
    side to remove it.

    screws of the lamp that are loosened in the previous 
    process to lock it in place.
    6.While putting the interlocking parts of the lamp cover 
    and the projector together, slide the lamp cover back in 
    place. Then firmly fasten the screw of the lamp cover.

    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.

    The air filter unit of this projector consists of a filter cover, two kinds of filters, and 
    a filter frame. The new double large filters system is expected to function longer. 
    However, please check and clean it periodically to keep ventilation needed for 
    normal operation of the projector.
    When the indicators or a message prompts you to clean the air filter, comply with 
    it as soon as possible. Replace the filters when they are damaged or too soiled. 
    To prepare new filters, make contact with your dealer and tell the following type 
    number.
