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 (Off)" on page 36 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 1/3.

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 "Indicators" on page 42.

The following Lamp warning displays will remind you to change the lamp.

Status

Message

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 36), you may continue to 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.

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.
