Lamp Life
Projector lamps have a finite life. The projected images will become darker and hues will become weaker
after a lamp has been used for a long period of time.
The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before replacing the
lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the POWER ON again. If the
LAMP indicator still displays red, replace the lamp.
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.
