Replacing the projection lamp
The lamp hour timer in the About menu counts the number of hours the
lamp has been in use. Fifty hours before the specified end of the lamp’s life,
the message “Replace lamp” briefly appears on the screen at each startup
and in the Interactive Display. After 50 additional hours, the lamp will no
longer light. You can order new lamp modules from your dealer. See
“Accessories” on page 41 for information.
1 Turn off the projector and unplug the power cable.
2 Wait 60 minutes to allow the projector to cool thoroughly.
3 Turn the projector upside down and remove the lamp door by loosening
the captive screw and then prying the lamp door out.

WARNINGS:
To avoid burns, allow the projector to cool for at least 60 minutes before
you replace the lamp.
Unplug the power cord before replacing the lamp.
Do not drop the lamp module. The glass may shatter and cause injury.
Do not touch the glass lamp screen. Fingerprints can obscure projection
