Each talkgroup in a UDSL can have up to three different levels of user-definable group scan
priorities which are used by your radio when deciding which call to follow when a call on one
talkgroup is active and a call on another talkgroup is received. The scan priority of each talkgroup in a

designate a selected talkgroup in each UDSL. You can add and remove talkgroups from a UDSL.
