7.29  EMERGENCY COMMUNICATIONS 
The M7300 mobile radio can transmit both emergency voice calls and emergency alerts over the entire 
network. OpenSky handles emergency calls and alerts with the highest priority. 
For critical voice communications, an emergency call can be raised on the default talk group or the 
currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is 
determined by the currently active profile. After successfully declaring an emergency on a talk group, the 
declaring radio’s microphone remains “hot” for a predetermined amount of time. In other words, the radio 
transmits audio for a period of time even when the microphone’s PTT button is not pressed. An 
emergency talk group is provided greater priority and infinite hang-time by the radio system’s 
infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group 
before the infrastructure assets are automatically taken away. Because an emergency call is handled on a 
talk group, it is received by all radios and consoles monitoring the talk group. 
An emergency alert is a data message sent by the radio to the MIS console (or any console capable of 
receiving it). It identifies the radio declaring the emergency, and the radio’s location (if the radio is 
equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the 
administrator configures the radio for alert notification only. 
7.29.1 Declaring an Emergency Call or Alert 
To declare an emergency call or emergency alert, press and release the orange Emergency button. This 
button is located just to the right of the 5-button Menu and Select keypad; see Figure 7-1 on page 18. The 
emergency is raised after the Emergency Raise Delay (default is one second). 
•  The OpenSky network administrator determines if the Emergency button is used to declare an 
emergency call or if it is used to declare an emergency alert. This is based upon the radio’s currently 
active profile. 
•  The OpenSky network administrator also determines if the emergency is declared on the currently 
selected talk group or a “default” emergency talk group. Again, this is based upon the radio’s 
currently active profile. A talk group upon which an emergency is declared on is considered an 
“emergency talk group.”
