Resetting the Lamp Operating Time

The projector has a built-in counter which keeps track of the lamp operating time. When the cumulative operating time reaches a certain point, it causes the replacement warning message to be displayed. Therefore, the counter needs to be reset after the lamp has been replaced with a new one. You can do this using the configuration menu.

TIP

Do not reset the lamp operating time except after the lamp has been replaced, otherwise the lamp replacement period will not be indicated correctly.

PROCEDURE

1	Connect the power cable, turn on the projector's
	power, and then press the [Menu] button.
	The configuration menu will be displayed.
	Remote Control		Projector

2	Select "Lamp-Hours Reset" from the "Reset" menu
	and then press the [Enter] button.

3 Select "Yes" and then press the [Enter] button.

The lamp operating time will then be reset.
