Emergency Communications
Your radio can send out an Alert or place Voice Calls over
the entire network in an emergency. OpenSky handles
Emergency Calls and Alerts with the very highest priority,
giving you and the people you serve access to the help you
need no matter how much traffic the network is handling.
 How to Place an Emergency Call
1.) Press the orange Emergency Button on your radio to
send an emergency alert. You’ll find the button just
above the Push-to-Talk button on the left panel (see
the Figure: Left Panel Components).
2.) You’ll hear nothing, but other users will hear the
Emergency Alert signal, a distinctive 3-tone burst of
sound.
3.) At the same time, the network enables an Emergency
Talk Group.
4.) Press the Push-to-Talk button to send your voice out
over the emergency talk group.
5.) All the radios in the Emergency Talk Group will
hear your call and see the emergency talk group
displayed on their radio, overriding any other displays
that may have been active there.
6.) When your emergency ends, your dispatcher must
clear the emergency call.
