When an alarm or warning condition is active, that condition is displayed on the LCD. The IRD
will not indicate (neither on LED's and LCD) multiple conditions; it will indicate only the most
critical condition. Alarm conditions are considered more critical than warning conditions, and
the list of alarm and warning conditions shown above and below are listed from most critical (1)
to least critical (4 or 12).
Note that the Alarm LED is only ON when the unit is either overheating or unable to produce video, or if a
secondary output has failed (and if control mask allows for alarm or warning display).
