The lamp hours timer in the Service Info menu counts the number of hours
the lamp has been in use. Twenty hours before the lamp life expires, a mes-
sage appears on the screen at startup indicating that you should change the
lamp. The LED on top of the projector also blinks red twice to indicate that
the lamp should be changed.
NOTE: You can order new lamp housings from www.infocus.com (in select
areas), your retailer or your dealer. Use only a replacement lamp with the
same type and rating as the original lamp.
1	Turn off the projector and unplug the power cord. If ceiling mounted,
	disconnect all cables and detach the projector from the ceiling mount.
2	Wait 60 minutes to allow the projector to cool thoroughly.
3	Turn the projector upside down on a soft cloth so that the lamp door is
	facing you. Remove the base or ceiling mount plate, if attached, by
	removing the 3 screws.
