Indicator Messages

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
8 for location). The follow-
ing tables describe the various states of the 4 LEDs.
