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" ( 35 ) and "Regarding the Indicator Lamps" ( 36 ) for details.)

1 witch the projector OFF, remove the power cord from the power outlet, and wait at least 45 minutes for the unit to cool.

2 Prepare a new lamp.

3 Check that the projector has cooled sufficiently, and gently turn it upside down.

4 Loosen the two screws as shown in the diagram, and remove the lamp cover.

Loosen the three screws, and

5 gently remove the lamp while holding the grips. Touching the inside of the lamp case may result in uneven coloring.

6

Install the new lamp and

tighten the three screws

firmly. Also steadily push the opposite side of the screwed lamp into the unit.

7

Replace the lamp cover in

position and tighten the two

screws firmly.

8

Gently turn the projector right-

side up.

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

Do not use with lamp cover removed.

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.

NOTE The 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.
