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 20 seconds.
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.
If replacing the lamp of a projector which has been installed on the
ceiling, you should always assume that the lamp is broken and
handle it with extreme care during removal. Furthermore, you
should stand to the side of the projector, not underneath it.
• Wait until the lamp has cooled down sufficiently before removing the
lamp cover. It takes a further one hour after the cool-down
gperiod
has finished for the lamp to be cool enough.
