Limited Talkgroup Scan
Limited Talkgroup Scan is one of the Scan Types used in a P25 Trunking system.
In Limited Talkgroup Scan, the transceiver waits for Group Calls from multiple Talkgroups on a control channel. If the
transceiver receives a Group Call message for the Talkgroup of the channel registered in the Scan List, the transceiver
migrates to a traffic channel and emits the audio. Also, the transceiver periodically checks for the presence of a signal on
a Conventional Channel (Analog or P25). If the time configured in
System Search Time
elapses, the transceiver scans
Conventional Channels registered in the Scan List.
If “Limited Talkgroup” is configured in
Scan Type (Scan List)
, a zone channel in a system where “P25 Trunking” is configured
in
System Type
and a zone channel in a system where “Analog Conventional” or “P25 Conventional” is configured in
System Type
can be registered as a member for List Scan.

Scanning All Target Zones for Scanning (Multi-Zone Scan)
In a P25 Conventional system, by using Multi-Zone Scan, the transceiver can scan all channels to be scanned in the target
zones.
If a scan starts in the zone where “Multi-Zone” is configured in
Scan Type
, Multi-Zone Scan is executed. Or, if the transceiver
migrates during the scan to the zone where “Multi-Zone” is configured in
Scan Type
, Multi-Zone Scan is executed.
The target zone for scanning is either the zone with
Zone Add
enabled by using KPG-D1/ D1N or the zone with Zone Add
enabled by using the
Zone Delete/Add
key.
The target channel for scanning is either the channel with
Scan Add
enabled by using KPG-D1/ D1N or the channel with
Scan Add enabled by using the
Scan Delete/Add
key.
