2.1.6   Emergency Communications 
Your control station 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 red  Emergency Button on your user interface to 
send an emergency alert. You will find the button just to the 
right of the 5-button Menu and Selector keypad. 
2.  You  will hear the emergency tone if you are successful. 
Other users will hear the  Emergency Alert signal, a 
distinctive 3-tone burst of sound. 
3.  At the  same time, the network enables the  Emergency 
Talkgroup provisioned in your current talkgroup. 
4.  The microphone is opened for a programmed amount of time 
in order to  send your voice out over the emergency talk 
group. 
5.  Based on your provisioned priorities, the radios in the 
Emergency Talkgroup  will hear your call and see the 
emergency talk group displayed on their radio. 
6.  When your emergency ends or if you inadvertently pressed 
the button, press and  hold the red  Emergency Button a 
second time to clear the emergency alert and call. Only you, 
the user who initiated the alert, dispatcher, or the network 
administrator can clear an emergency.
