includes only voice communication, upon receiving the Call-Out call. The user can clear the Fallback
mode only manually.
8.3.5 Call-Out test
Dispatcher is able to test this feature by using Call-out test. Terminal will display ‘Call-Out Test’ and
generate the alert tone. Only one soft key is available for the user with the label Test OK. After
responding the display will return to its previous mode.

• it is sent out to the larger group of people
• user is able to respond with any key stroke and after that will be moved to information
phase
It is sent several times to raise reliability.
