Call-Out
This feature allows the user to receive call-out alerts. When
the Call-Out messages has been received by the radio, it
interrupts current services and attends to the call-out alert
without any further delay. After call-out alert has been
cleared, the radio exits Call-Out mode and reverts back to
normal mode. User is able only to receive Emergency Calls
during Call-Out mode. There are four types of the Call-Out
alert:
• Normal call-out
• Storm plan - it is sent to a group several
time to raise reliability. User can only
accept the Call-Out by pressing any button
and is moved to information phase (soft
keys are not labelled).
• Fallback Mode - it includes only voice communication. It
can be cleared manually
Fallback is only possible when Radio is in Local Site Trunking.
• Test Call-Out - dispatcher has the ability to test this
feature. Radio is generating the tone with "Call-Out Test"
on the display. Only one softkey is enabled "Test OK" to
confirm and to clear the test.
Interactions when the user is in other mode:
• TXI Mode - users can read the message but they can not
respond to it. They 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 the Call-out alert are ignored.
