Starting a group call
A group call is a half-duplex voice connection. While one subscriber speaks, all other
subscribers in that group listen to this call. After that, the other subscribers can
answer the call, one after the other.
Prerequisite:
The channel is not occupied by a call.
Perform the following steps:
1.
Press the
‹PTT (transmit key)› (6)
and keep it pressed.

The connection with the subscribers in the called group is set up. The display
shows the name or the call number of the group (GSSI).
After a short time, your speech enabling signal is transmitted unless another sub-
scriber is transmitting. The radio set can also signal “speech enabling” with an
audible signal, provided that the signal profile in use is configured for “Speech
Authorising” signalling.
