Maintenance

Replacing the Lamp

Caution :

•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 that has been installed to the ceiling, you should always assume that the lamp is broken and remove the lamp cover very carefully.

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

enough.

Procedure

1 Turn off the projector power, wait for the cool-down period to end, and then disconnect the power cable.

The cool-down period lasts for about 20 seconds. The actual time will vary depending on the external air temperature.

2 Wait until the lamp has cooled down, and 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.

Put your finger into the recess, and pull straight out to remove the lamp cover.

3 Loosen the two lamp fixing screws.

Use the screwdriver that is supplied with the spare lamp or a Phillips screwdriver to loosen the two lamp fixing screws that are securing the lamp to the projector.
