• Page 5: Alarm Notice

  Automatic The symbol indicates that all alarms are disabled. Ouman A203 can generate alarms for several different reasons. In the event of an alarm, an alarm window pops up showing de- tailed alarm information and a beeping alarm signal goes on, if the alarm sound is not turned off (see page 27).
