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 8 for location). The following tables describe the various states of the 4 LEDs.
