The alarm settings are divided by parameters and can be traced back to the display menu pages
described in "Mode setting and switching times"
3.2.4.2 Audio Levels
In this window you set the alarm thresholds for the MPX and L / R channels.
To be considered valid, the values read by the channels should be higher than or equal to those set.
MPX -LR Audio Level: audio level (100% adjustable) (on "Audio level: On / Off" in the "Alarm Setup"
window)
MPX min level threshold %: input level MPX input signal expressed as a percentage and converted to dB
(on "MpxIn" display in the THRESHOLDS window)
L/R min level threshod %: the audio level of the signal coming from the satellite receiver or other source.
The control is done on both channels, so if a channel is disconnected or attenuated, the source will still
be considered an alarm even if the other channel has the correct level. (on "LR" display in the
THRESHOLDS window).
