Service: 824-848.9875 MHz and 869-893.9875 MHz
Working Memory
1800 programmed objects using flexible “Scannable Object” system.
Program and scan conventional channels, trunking talkgroups, limit
searches, service searches, and Signal Stalker II configurations as
“Scannable Objects” that are created, edited, grouped and scanned
using common user interface conventions.
Virtual Scanners
21 Virtual Scanner (V-Scanner) folders, each capable of holding the entire
contents of working memory, for a total storage capacity of over 37,800
objects.
Searches
Seven preprogrammed dedicated service searches, one dedicated limit
search. Any service or limit search can be programmed and scanned as an
object alongside conventional channels and trunking talkgroups.
Priority
Talkgroup and conventional channel priority, selectable priority sample
rate and priority sample during trunking talkgroup call.
