Replacing the Projection Lamp

The lamp hour counter in the menus counts the number of hours
the lamp has been in use. The LP740B uses a metal halide bulb.
These types of bulbs deteriorate over time. Replace the lamp
when the brightness is no longer acceptable. The lamp LED
blinks slowly after 950 hours; after 1000 hours a "lamp replace"
message appears on the screen. You can order new lamp modules
from your In Focus dealer. See "Accessories" on page 34 for infor-
mation.
Follow these steps to replace the projection lamp:
1 Turn off the projector and unplug the power cord.
2 Wait 30 minutes to allow it to cool thoroughly.
3 Place the projector on its side, then remove the 2 screws on the
lamp module door (Figure 16).
4 Pull the lamp door up and remove it.
