Types of Call-Out Alerts
There are four types of the Call-Out alerts:
Normal Call-Out – an alert message that is sent by a dispatcher either to a single radio or to a group
of radios.
Storm Plan – an alert message that is sent by a dispatcher to a group of radios. To raise its
reliability, it is sent several times. You are not able to respond to the Call-Out alert and any key
press takes you to the information phase.
Fallback Mode – an alert message that is limited only to voice communication. To initiate this type
of Call-Out, press a One-Touch key predefined by your service provider. It can be cleared manually.
NOTICE: Fallback is only possible when the radio is in Local Site Trunking.
Test Call-Out – a special Call-Out alert that is sent by the dispatcher to test this feature. On
receiving the Test Call-Out, the radio plays a tone and displays Test Call-Out. To respond and
clear the alert, press the Test OKSOFT key.
Call-Out Modes Interaction
Call-Out feature operation is different in other modes:
TXI Mode — you can read the message but you cannot respond to it. You have an option to leave
the TXI Mode by pressing soft key or reject the Call-Out message.
DMO Mode — Call-Out is not supported.
Emergency Mode — all Call-out alerts are ignored.
Call-Out Service Phases
In the Call-Out mode there are following phases:
Alerting phase — receives a Call-Out message. The alarm tone indicates the message. Text is
displayed and you have following options to use: Accept, Reject or MENU. If you accept the alert, no
other service from this point can interrupt.
NOTICE: You can stop the alert tone by pressing PTT or any of the soft keys.
Information phase — you are still in the Call-Out mode and you can receive more detailed
information about the incident that occurred through subsequent text or the voice message. You
can query for more information using voice group call or Call-Out text function which enables you to
send a text message. You can always respond and send back the text or the voice message using
voice group call.
