Replacing the Projection Lamp
WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you open
the lamp module door. Never
extract the lamp module while the
lamp is operating.
The lamp hour counter in the Status menu counts the number of
hours the lamp has been in use. Replace the lamp when the
brightness is no longer acceptable. You can order new lamp mod-
ules from your InFocus dealer. See “Accessories” on page 36 for
information.
Follow these steps to replace the projection lamp:
1
Turn off the projector by unplugging the power cord.
2
Wait 30 minutes to allow the projector to cool thoroughly.
3
Invert the projector on a flat surface, then insert a small screw-
driver or other flat object into the tab on the lamp module
door (Figure 19).
