Timing Of Replacing The Lamp - ViewSonic PJD7820HD User Manual

Timing of replacing the lamp

When the LAMP indicator light 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.
CAUTION
The LAMP indicator light and TEMPerature indicator 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
page 54 for details.
The following lamp warning displays will remind you to change the lamp.
Install a new lamp for optimal performance. If the
projector is normally run with Economic selected
(See "Setting Lamp Mode as Economic" on page
49), you may continue to operate the projector
until the next hour 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 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 must be replaced when
you see this message.
The lamp MUST be replaced before the projector
will operate normally.
