• 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.
NOTE
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" ( ) and "Regarding the
Indicator Lamps" ( ) for details.)

witch the projector OFF,

shown in the diagram, and

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.
