Replacing the Lamp•
••
•If the lamp stops working and needs to be replaced, there is the danger that the lamp may
break when handled.
If replacing the lamp of a projector which has been installed to the ceiling, you should
remove the projector from the ceiling before replacing the lamp. If the projector cannot be
removed from the ceiling, you should always assume that the lamp is broken and handle it
with extreme care during removal. Furthermore, you should stand to the side of the
projector, not underneath it.
