Use and replacement of the lamp
When the Lamp indicator lights up red or a message displays suggesting it is time to replace
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a
malfunction in the projector and in some instances the lamp may explode.
For more information on projector warnings, refer to
"Indicators" on page 53
.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too
hot. Turn the power off, allow the projector to cool down before checking that the dust filters
are not clogged (page

Message
Status
The lamp has been in operation for 1980 hours. Install
a new lamp for optimal performance. If the projector
is normally run with "Economic Mode" selected (see
"Selecting a preset mode" on page 35
), you may
continue to operate the projector until the 2980 hour
lamp warning appears.
The lamp has been in operation for 2980 hour, the
power will shutdown in 20 hours time. A new lamp
should be fitted to avoid the inconvenience when the
projector runs out of lamp time.
The lamp has been in operation for over 3000 hours.
This message will flash in the center of the screen
together with the Lamp indicator lighting up red for
40 seconds. The projector will shutdown after 40
seconds. The lamp MUST be replaced before the
projector will operate normally.
It is strongly recommended that you replace the lamp
at this age. The lamp is a consumable item. With the
usage time increase, the lamp brightness diminished
gradually. This is normal lamp behavior. You can
replace the lamp whenever you notice that the
brightness level has significantly diminished. If the
lamp is not replaced beforehand, it must be replaced
after 3000 hours usage.
