permit scanning, it is automatically enabled again when a channel is selected that
permits scanning.
• Up to 256 scan lists, each with up to 512 talk groups from the same system can be
programmed. The selected scan list can be temporarily changed and edited as described
in Section 4.10.1.
• In addition to calls on channels in the scan list, pages, private/unit calls, and telephone
calls are received while scanning. Private and telephone calls are not interrupted by
priority messages.
6.11.1 Priority Talk Group Sampling
The 5100 ES radio supports Dual Priority talk groups in all trunking and conventional
formats. When scanning, messages on a non-priority talk group are interrupted by
messages on the priority talk group. Priority scanning must also be supported at the system
level for it to occur as programmed in the radio.
6.12 Dynamic Regrouping
The dynamic regrouping feature allows a dispatcher to change the current talk group or
switch radios to a predefined regrouping channel to receive an important message. When
the console issues a regroup order, the radio switches to the pre programmed regroup talk
group.
If the Cancel Dynamic Regrouping option switch or menu parameter is programmed, it
can be used to exit the dynamic regrouping mode if desired.
Otherwise, if the lock mode was not specified, the selected talk group can be manually
changed and the previous talk group is reselected. If a locked regroup command is
received, the displayed talk group cannot be changed manually or by cycling power. It can
be changed only after a clear order is received from the console.
Dynamic regrouping operates as follows:
1
When this command is received, a 765 Hz tone sounds every 25 ms for 300 ms and the
radio automatically changes to the regrouping channel. “Dyn Regrp” is displayed.
2
Talk and listen as usual. When dynamic regrouping is canceled by the dispatcher, a
short tone sounds. If a standard channel is not selected after this occurs, transmission is
not allowed if the talk group is assigned as a dynamic regrouping talk group only. If it is
assigned as a normal talk group, normal transmissions are allowed.
