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 consult your dealer or go to
http://www.BenQ.com
before installing a new lamp. An old lamp
may cause a malfunction in the projector and in some instances the lamp may explode.
The following Lamp warning displays will remind you to change the lamp.
• The apparent brightness of the projected image will vary depending on the ambient lighting conditions, selected
input signal contrast/brightness settings, and is directly proportional to projection distance.
• The lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This is
normal and expected behavior.
• 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
Install a new lamp for optimal performance. If the projector is
normally run with
Economic
selected (See
the Light Usage Time on page 37
), you may continue to operate
the projector until the next hour lamp warning appears.
Press
OK
to dismiss the message.
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.
Press
OK
to dismiss the message.
The lamp MUST be replaced before the projector will operate
normally.
Press
OK
to dismiss the message.
