INDICATOR FUNCTION
Glows green if AC input and projector power supplies are okay.
Glows red if not.
Glows red to warn of an over-temperature condition.
Glows red if the projection lamp burns out.
Power
The power indicator glows green after you turn on the AC power switch and
the projector completes a self check.
Over Temperature
The indicator illuminates if the projector overheats.
An over-temperature condition automatically turns off the power to the
lamp until the projector cools.
If an over-temperature condition occurs, perform the following checks while
you allow the projector to cool:
• Verify that the room temperature is below 104° F (40° C) when projecting
in color or 95° F ( 35° C) when projecting in Workgroup (monochrome)
mode.
• Check the intake and exhaust vents. Clear any obstruction to the air flow.
