Group scan-
ning The radio set may include several scan lists. If one of the scan
lists is marked as "selected" and if the scan function is activated,
your radio set will monitor the radio traffic in all associated groups.
Consequently, you can listen to several important channels
without switching over. This feature is referred to as "Group scan-
ning". The scan lists are saved in the radio set by means of pro-
gramming.
Group A group unites several subscribers who communicate directly with
one another. Calls to a group reach all subscribers within this
group at the same time. Other subscribers cannot heat these
group calls. Group calls are possible even when not all users of
this group can be reached, e.g. because a radio set is switched
off.
GSSI Group Short Subscriber Identity: Call number of a group in the
TETRA network
