THE LAMP (continued)

Replacing the lamp

All projector lamps will wear out eventually. If used for long periods of time, the image could become darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps early. If the LAMP indicator turns red, the lamp needs to be replaced. (See "Regarding the Indicator Lamps" (Vol.2 9 ) for details.)

1	Turn off the projector, and unplug the
	power cord. Allow the lamp bulb to cool
	for at least 45 minutes, and prepare a
	new lamp (serial number: DT00571)
2	After making sure that the projector has
	cooled adequately, slide the knob of a

lamp cover lock as shown in the figure. Then, one side of the lamp cover is raised. Pull up the lamp cover and remove it, as shown in the figure
