Alarm settings (factory setting)
Definition:
Pre-acknowledgement: If, during the alarm condition, the acknowledgement is
actuated (by pressing the OK button), the audible alarm and the vibration are
switched off. The alarm is only fully reset (LED and display) once the alarm
condition no longer exists.
Acknowledgement: If an acknowledgement is actuated when the A1 alarm
condition no longer exists (by pressing the OK button), all alarm elements will be
reset.
If the A2 and A1 alarms are configured as acknowledgeable, a pre-
acknowledgement or acknowledgement of the A2 alarm will pre-acknowledge the
A1 alarm or fully acknowledge it if no further alarm condition exists.
