Replacing the Lamp
The projection lamp typically lasts for about 2000 hours of use
(in high brightness mode) or 3000 hours (in low brightness mode). It
is time to replace the lamp when:
■ The projected image gets darker or starts to deteriorate.
■ The lamp light is flashing orange.
■ The message Replace the Lamp appears on the screen when the
lamp comes on. Replace the lamp as soon as possible. If you
continue to use the lamp after you see this message, there is a
greater possibility of the lamp breaking.
note
You can check to see how
many hours the lamp has
been used. See page 61.
Turn the projector off when
not in use. Continuous
24-hour-a-day use may
reduce the overall life of this
product.
