Using a small, flat-blade screw driver, remove the two
screws on the bottom of the projector on the outside of the

overheat.

Pull the lamp cover up and remove it.

Removing the lamp module cover
CAUTION: Be sure to replace
the projection bulb as soon as
possible after the lamp monitor
light comes on. If the lamp
remains in use too long, there is a
danger of lamp explosion. If this
happens, your LitePro will be
severely damaged.
