TIP

•The lamp replacement message is set to appear after the following periods of time in order to maintain the initial brightness and quality of the projected images.

·When used continuously at high luminance: Approx. 1900 hours

·When used continuously at low luminance: Approx. 2900 hours

"Brightness Control"p.92

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.

•Depending on the characteristics of the lamp and on the way it has been used, the lamp may become darker or stop working before the lamp warning message appears. 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.

•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
