Using the Trunked Announcement
The announcement capability allows you to make
announcements to the entire user group, as well as monitor
talkgroup calls and other announcements.
Announcement calls are handled in two different ways,
depending on the trunked central controller configuration. The
two types are called ruthless and non-ruthless preemption.
• Ruthless Preemption:
When a ruthless preemption announcement call is initiated,
the requesting radio begins transmitting immediately. All
associated talkgroup calls taking place on other channels are
immediately halted, and the radios are steered to the
announcement call.
Transmitting radios continue to transmit until the PTT button
is released, at which time they also unmute for the
announcement call. Individual calls (Private Conversation and
telephone interconnect) are not affected.
• Non-Ruthless Preemption:
When a non-ruthless preemption announcement is initiated,
the initiating unit receives a telephone-type busy tone,
followed by a call back when all associated talkgroup
conversations end.
Once an announcement call is pending, any attempts by
other users to initiate a talkgroup call will result in a
telephone-type busy tone. These users will not receive a call
back until the announcement call is complete.
Initiating an Announcement
If your radio has been programmed to allow announcement
calls:
Procedure:
1 Press the Mode Knob to locate the announcement-group
mode.
2 Press the microphone PTT button to initiate the
announcement.
