Maintaining the Projector
Follow these steps to replace the lamp:
1. Turn off the projector and unplug the power cord.
2. Let the projector cool for at least an hour (if it has been on). The
lamp is extremely hot immediately after use.
3. Loosen the lamp cover screw (you cannot remove it). Then slide
the lamp cover off.
4. Loosen the two screws holding the lamp in place (you can’t
remove them).
warning
Let the lamp cool fully
before replacing it.
In the unlikely event that
the lamp has broken, small
glass fragments may be
present and should be
removed carefully to avoid
injury. If the projector has
been installed on the ceiling,
you should stand to the side
of the lamp cover, not
underneath it.
If the lamp is used after the
replacement period has
passed, the possibility that
the lamp may break
increases. When a lamp
replacement message
appears, replace the lamp
with a new one as soon as
possible, even if it is still
working.
Loosen, but don’t
remove these screws
