Replacing the Lamp

CAUTION

•If you are replacing the lamp because it has stopped working, it is possible that the lamp is broken.

If replacing the lamp of a projector which has been installed on a ceiling, you should always assume that the lamp is broken and be extremely careful when removing the lamp cover.

•Wait until the lamp has cooled down sufficiently before removing the lamp cover. It takes a further one hour after the cool-downgperiod has finished for the lamp to be cool enough.

PROCEDURE

1	Turn off the projector's power, wait until the cool-
	down period has ended and a "pip-pip" confirmation

buzzer sounds, and then disconnect the power cable.

The cool-down period lasts for about 20 seconds.

2	Wait until the lamp has cooled down, then remove the
	lamp cover from the base of the projector.

It takes approximately one hour for the lamp to cool down by itself after the cool-down period has finished.

Loosen the lamp cover fixing screw with the screwdriver that is supplied with the spare lamp (or your own cross head screwdriver).

Then slide the lamp cover straight forward and lift it to remove.

3 Loosen the two lamp fixing screws.
