Alarms and Events

5.0 Alarms and Events

Alarms are indicated by the red lamp (above the left hand corner of the keyboard) and a 30 seconds acoustic signal. An alarm is registered in the alarm stack as long as it is present, and if more in the same order as they arise.

Certain alarms, such as battery alarms, need resetting. See section 4.0 Parameter Settings.

All alarms are also registered in an event logger and remains there in a stack with room for 250 events. The events are stored in the same order as they arose - showing the latest first.
