LOOSE FILTER NOTICE

Please shut down the projector, then check the filters and covers. Refit if necessary (refer to User's Manual).

Lamp information

Use and replacement of the lamp

When the Lamp indicator lights up red or a message displays 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 information on projector warnings, refer to "Indicators" on page 53.

The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. Turn the power off, allow the projector to cool down before checking that the dust filters are not clogged (page 48). 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

 

 

 

 

The lamp has been in operation for 1980 hours. Install

 

 

 

 

 

 

 

 

a new lamp for optimal performance. If the projector

 

 

 

 

is normally run with "Economic Mode" selected (see

 

 

 

 

"Selecting a preset mode" on page 35), you may

 

 

 

 

continue to operate the projector until the 2980 hour

 

 

 

 

lamp warning appears.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The lamp has been in operation for 2980 hour, the

 

 

 

 

 

 

 

 

power will shutdown in 20 hours time. 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

 

 

 

 

together with the Lamp indicator lighting up red for

 

 

 

 

30 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.
