f How to replace the lamp
Attention
• The lamp replacement message is set to appear after the following
time periods in order to maintain the initial brightness and quality
of the projected images.
s
"Brightness Control" p.43
- When used continually at high brightness: About 2900 hours
- When used continually at low brightness: About 3900 hours
• If you continue to use the lamp after the replacement period has
passed, the possibility that the lamp may explode increases. 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 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.
Warning
When replacing the lamp because it has stopped illuminating, there
is a possibility that the lamp may be 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 you
should stand to the side of the lamp cover, not underneath it.
Remove the lamp cover gently. Small pieces of glass may fall out
when the lamp cover is opened. If pieces of glass get into your eyes
or mouth, seek medical advice immediately.
Caution
Wait until the lamp has cooled down sufficiently before removing
the lamp cover. If the lamp is still hot, burns or other injuries may
result. It takes about one hour after the power has been turned off
for the lamp to be cool enough.
