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.
Do not attempt to replace the lamp yourself. Contact the qualified service
personnel for replacement.
The Lamp indicator light and Temperature warning light will light up if the
lamp becomes too hot. See
on page 65 for details.
The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the
actual on-screen instructions to prepare and replace the lamp.
Status
Install a new lamp for optimal performance. If
the projector is normally run with Economic
selected ("Setting Lamp mode" on page
you may continue to operate the projector
until the next lamp warning appears.
A new lamp should be fitted to avoid the
inconvenience when the projector runs out of
lamp time.
It is strongly recommended that you replace
the lamp at this stage. 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.
The lamp MUST be replaced before the
projector will operate normally.
"XXXX" shown in the above messages are numbers that vary depending
on different models.
