MAINTENANCE AND SECURITY
Replacing the Projection Lamp
The projection lamp should be replaced when it burns out. It should only be replaced with a certified
replacement part, which you can order from your local dealer.
Important:
1. The lamp contains a certain amount of mercury and should be disposed of according to local or-
dinance regulations.
2. Avoid touching the glass surface of the new lamp: Doing so may shorten its operation life.
Warning:
1. Be sure to turn off and unplug the projector at least an hour before replacing the lamp. Failure to
do so could result in a severe burn.
2. It is recommended that you do not attempt to replace the lamp while the projector is installed on
a ceiling. If you do attempt this, wear protective goggles to prevent glass from a ruptured lamp get-
ting into your eyes.

Remove the screw on the lamp com-
partment cover (B) and then lift the
