Turning the Projector Off

TIP

•If the Power indicator is flashing orange, operation of the [Power] buttons is disabled. Wait until the indicator lights continuously. •If "Standby Mode" in the configuration menu is set to "Network ON", fans will continue operating. This is normal and does not indicate a problem.

4	If not using the projector for a long period, unplug the
	power cable from the electrical outlet.

CAUTION

Do not disconnect the power cable from the outlet while the Power indicator is still flashing orange, otherwise it may result in errors in projector operation and reduce the lamp unit operating life.

5 Attach the lens cover.

Attach the lens cover to the lens when not using the projector, in order to prevent the lens from getting dusty or dirty.
