 Notes on the replacement of the lamp unit
  •  The luminous source of the lamp is made of glass and may burst if you hit 
it against a hard surface or drop it.
    Please handle with care.
  •  A Phillips screwdriver is required for replacement of the lamp unit.
  • When replacing the lamp unit, be sure to hold it by the handle.
• When replacing the lamp because it has stopped illuminating, there is a  
possibility that the lamp may be broken. If replacing the lamp of a projec- 
tor which has been installed on the ceiling, you should always assume 
  that the lamp is broken, and you should stand to the side of the lamp 
  cover, not underneath it. Remove the lamp cover gently. Small pieces of 
  glass may fall out when the lamp cover is opened. If pieces of glass get 
  into your eyes or mouth, seek medical advice immediately.
  • The lamp contains mercury. Consult your local municipality or your dealer 
about correct disposal of used lamp units.
 When to replace the lamp unit

replacement of the lamp unit is necessary. When the projection lamp of the projector reaches its end of life, the 
lamp replacement icon appears on the screen and <LAMP> indicator lights yellow. Replace the lamp with a new 
one promptly.
