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
Ensure your radio has been programmed to allow
announcement calls.
1 If channel is set as the primary mode, turn the MFK
to locate the announcement-group mode.
2 Press the PTT button to initiate the announcement.
Ignition Switch Options
This feature allows the user to select the functionality of the
radio based on the Ignition State of the radio user’s vehicle.
Blank
This option allows the user to power on and power off the
radio through the Power button regardless of the current
state of the Ignition.
