c Caution:
If the lamp stops working
and needs to be re-
placed, there is the dan-
ger that the lamp may
already be broken.
If replacing the lamp of a
projector which has been
installed to the ceiling,
you should always as-
sume that the lamp is
broken and handle it with
extreme care during re-
moval. Furthermore, you
should stand to the side
of the projector, not un-
derneath it.
Turn off the power, wait
until the projector cools
down and the "beep beep"
tone sounds, then discon-
nect the power cable.
* Wait until the lamp cools
down (takes approxi-
mately 1 hour).
Remove the lamp cover.
To remove the cover, use a
screwdriver (the one supplied in
the same package as the option-
al lamp) inserted into the lamp
cover open switch.
Securely tighten the
lamp fixing screws.
Install the lamp cover.

ment warning message to be
