Lamp information
Calculation of lamp hour
When the projector is in operation, the duration (in 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
= 1 (hours used in Economic mode) + 3/2 (hours used in normal mode)
See " Economic Mode" on page 38 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is, using
the projector in Economic mode helps to extend the lamp life by 1/2.
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 "Indicators" on page
45 .
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.
Message Status
Total (equivalent) lamp hour has reached 2000 hours.
Install a new lamp for optimal performance. If the
projector is normally run with "Economic Mode"
selected (See
" Economic Mode" on page 38), you may
continue to operate the projector until the 2950 hour
lamp warning appears.
Total (equivalent) lamp hour has reached 2950 hour.
A new lamp should be fitted to avoid the
inconvenience when the projector runs out of lamp
time.
Total (equivalent) lamp hour has reached 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. With the
usage time increase, the lamp brightness diminished
gradually. 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
after 3000 hours usage.
