The talkgroups are organized into scan lists that are user selectable. Only one scan list can be
active and the terminal continuously monitors the talkgroups of the scan list for activity. The terminal
will also monitor the group on which scan was started, this may be an ‘Announcement Talkgroup’
(ATG).
By assigning priorities to the talkgroups defined in the scan list, the handset is capable of accepting
calls that have higher priority than the on-going call.
