If an alarm condition develops, an alarm will be emitted:
17.3.2 Priority
Different alarms have differing priority levels: high , medium and low . Higher priority
alarms are signaled visually and audibly before lower priority ones. When alarms of
the same priority level occur at the same time, the most recent alarm will be shown on
the display first.
The user interface displays the higher-priority alarm on the left hand side. If multiple
alarms have the same priority level, the most recent one will be displayed on the left.
