Replacing the Lamp
All projector lamps will burn out eventually. If used for long periods of time, the image could become darkened, and the color and contrast could be impacted as well. We recommend that you replace your lamps early. If the LAMP indicator turns red, it is a caution signal that the lamp needs to be replaced.
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, then switch the power ON again. If the LAMP indicator is still red, replace the lamp.
1Switch the projector OFF, remove the power cord from the power outlet, then wait at least 45 minutes for the unit to cool.
2Prepare a new lamp.
3Check that the projector has cooled suffi- ciently, then gently turn it upside down.
4Loosen the screw as shown in the diagram, then remove the lamp cover
5Loosen the two screws, then gently remove the lamp while holding the grips. Touching the inside of the lamp case cavity may result in uneven coloring.
6Install the new lamp then tighten the two screws firmly. Also steadily push the oppo- site side of the screwed lamp assembly into the cavity.
7Replace the lamp cover in position then tighten the screw firmly.
8Gently turn the projector
ATTENTION
•Ensure that the screws are screwed in firmly. Loose screws could result in damage or injury.
•Do not turn on with lamp cover removed.
•Do not reset the lamp timer without replacing the lamp. Always reset the lamp timer when the lamp is replaced.
