PROCEDURE

Turn the projector's power off, wait for the cool-down

period to end, and then disconnect the power cable.

The cool-down period lasts for about 30 seconds.

TIP

• The replacement warning message is set to appear after about 1900

hours of lamp use in order to maintain the initial brightness and

quality of the projected images. If you continue to use the lamp after

this period, the possibility of the lamp breaking becomes greater.

When the lamp replacement message appears, replace the lamp with

a new one as soon as possible, even if it is still working.

• The warning message appears after about 1900 hours of use, but the

actual life of each individual lamp will vary depending on the

characteristics of the lamp and on the way it has been used, and

some lamps may stop operating before 1900 hours of use. You should

always have a spare lamp ready in case it is needed.

• Contact your dealer for a spare lamp.

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 to the

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-down

period

has finished for the lamp to be cool enough.
