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, or a message prompts you to replace the lamp when you power up the projector, the lamp needs to be replaced. (See "Related Messages" ( 38 ) and "Regarding the Indicator Lamps" ( 39 ) for details.)

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.

 

 

 

 

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.

ATTENTION • Make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.

Do not reset the lamp timer without replacing the lamp. Reset the lamp timer always when replacing the lamp. The message functions will not operate properly if the lamp timer is not reset correctly.

When the lamp has been replaced after the message of “CHANGE THE LAMP .....THE POWER WILL TURN OFF AFTER 0 hr.” is displayed, or the LAMP indicator is red, complete the following operation within 10 minutes of switching power on.

NOTEThe LAMP indicator is also red when the lamp unit reaches high temperature. Before replacing the lamp, switch power off, wait approximately 20 minutes, and switch power on again. If the LAMP indicator is still red, replace the lamp.
