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 = hours used in Economic mode + hours used in normal mode

See "Economic Mode (off)" on page 38 for more information on Economic mode.

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 1/4.

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 47.

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.

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 (off)" on page 38),

 

 

 

 

 

you may continue to operate the projector until the

 

 

 

 

 

2950 hour lamp warning appears.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The lamp has been in operation for 2950 hours. A

 

 

 

 

 

 

 

 

 

 

new lamp should be fitted to avoid the

 

 

 

 

 

inconvenience of shutdown 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.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If this warning message displays, the projector will

 

 

 

 

 

 

 

 

 

 

shutdown in 40 seconds. The lamp MUST be

 

 

 

 

 

replaced before the projector will operate normally.
