Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears 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.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes
too hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp
indicator still lights up after turning the power back on, please contact your dealer. See
for details.
The following Lamp warning displays will remind you to change the lamp.

The lamp has been in operation for 3000 hours.
Install a new lamp for optimal performance. If the
projector is normally run with Eco. selected (See
"Getting to know the lamp hour" on page 68
), you
may continue to operate the projector until the

The lamp has been in operation for 3950 hours. It
is strongly recommended that you replace the lamp
at this age. The lamp is a consumable item. The
lamp brightness diminishes with use. 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 should be replaced after
3950 hours usage.
