1.1 Basic view
Ouman H23 can generate alarms for several dierent reasons. In the
event of an alarm, an alarm window pops up showing detailed alarm
information and a beeping alarm signal goes on.
If there are several unacknowledged alarms, the latest activated alarm
is always shown in the display. As soon as all active alarms have been
acknowledged, the alarm window disappears and the alarm signal goes
o.
Alarm signal of all active alarms may also be muted by pressing Esc
button. When you press Esc, the alarm signal stops and the last alarm
windows disappear from the display.
You may look into the alarms later by going to ”Alarms” > ”Active alarms”.
If an alarm has not been acknowledged, an exclamation mark will ap-
pear in the beginning of the row.
