6.1 Error Displays
When the power is turned on, all of the lamps go on for a few seconds while a self test is performed.
If the self test ends normally, self calibration starts and all lamps except for the CALIBRATION lamp
go off. Do not send any remote commands until self calibration is completed. If an error was
detected during the self test, the ERROR lamp remains on.
The following lists lamp on patterns along with their causes and required responses.
