1 If multiple messages/alarms are activated at the same time, only the last
message/alarm is shown. If this is cancelled, the other messages that are
still active are no longer displayed.
2 The message can be assigned the collective alarm function, which means
that the collective alarm is activated as soon as at least one of the
messages assigned to it is activated. The collective alarm can be assigned
to each of the 4 optional relays. The collective alarm is then always the
same, as it can only be defined once.
Execute Confirm message function (via control keys at transmitter):

The message/alarm is no longer shown on the display. 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.
