Lamp information
Calculation of lamp hour
When the projector is in operation, the duration (by hours) of lamp usage is automatically calculated by the
built-in timer. The method of calculating the equivalent lamp hour is as follows:
Total (equivalent) lamp hour = 3/4 (hours used in Economic mode) + 1 (hours used in normal mode)
See
"Economic Mode" on page 35
The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using the projector in
Economic mode helps to extend the lamp hour by 1/3.
Warning message
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.
For more detailed information on projector warnings, please refer to
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.
The following Lamp warning displays will remind you to change the lamp.

Status
The lamp has been in operation for 2800 hours. Install a new lamp for
optimal performance. If the projector is normally run with "Economic
Mode" selected (See
"Economic Mode" on page
operate the projector until the 2950 hour lamp warning appears.
The lamp has been in operation for 2950 hour. 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 for about 30 seconds together with the
Lamp indicator lighting up red for 40 seconds.
It is strongly recommended that you replace the lamp at this age. The lamp
is a consumable item. Its timer in the projector helps provide information
on the calculated lamp usage time. With the usage time increase, the lamp
brightness diminished gradually. This is normal lamp behaviour. 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.
If this warning message displays, the projector will shut down in 40
seconds. The lamp MUST be replaced before the projector will operate
normally.
