Indicator Messages
Several indicator messages are used by the projector to alert users of problems with
setup or internal parts. The LEDs on the top surface of the projector show the status of
the power, lamps 1 and 2 as well as the general working order of the projector through
the status LED (see OSD Controls and Status LEDS on page
for location). The follow-
ing tables describe the various states of the 4 LEDs.
