Perform the Confirm message function (acknowledgement of the
alarm via the control keys on the transmitter):
• The message/alarm is no longer shown on the display and the
optical alarm goes out, where applicable. If multiple
messages/alarms are active at the same time, all are reset
simultaneously.
• If at least one message is assigned to the collective alarm, the
collective alarm is reset. If the collective alarm is set on a relay,
the relay is also reset, meaning switched to its neutral position.
