Maintenance
Cleaning the lens
1Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
• Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2Lightly wipe the cleaning cloth over the lens in a circular motion.
Replacing the projection lamp
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.
1Turn off the projector and unplug the power cord. If ceiling mounted,
disconnect all cables and detach the projector from the ceiling mount.
2Wait 60 minutes to allow the projector to cool thoroughly.
3Turn 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.

4Push the 2 tabs on the lamp door toward the front of the projector and
lift the lamp door off.
5Loosen the three captive screws that attach the lamp housing to the pro-
jector.
6Detach the lamp connector from the projector by depressing the locking
tab on the connector and lightly pulling it free.
WARNING:
To avoid burns, allow the projector to cool for at least 60 minutes
before you replace the lamp.
Be extremely careful when removing the lamp housing. In the
unlikely event that the bulb ruptures, small glass fragments may be
generated. The lamp housing is designed to contain these frag-
ments, but use caution when removing the lamp housing. Before
replacing the lamp, clean the lamp compartment and dispose of
cleaning materials. Wash hands after lamp replacement. This prod-
uct has a lamp which contains a very small amount of mercury. Dis-
pose of it as required by local, state or federal ordinances and
regulations. For more information see www.eiae.org.
7Carefully remove the lamp housing. Dispose of the lamp in an environ-
mentally proper manner.
8Install the new lamp housing and tighten the screws.
9Re-attach the lamp connector to the projector. The locking tab should
engage when the connector is fully plugged in.
