Emergency Alert
NOTE:
This is a Software Selling Feature.
This feature allows the radio to send emergency alerts to other radios within its Direct Mode Operation
(DMO) coverage by pressing the
Emergency
button.
Even in Trunked Mode Operation (TMO), the radio monitors a special DMO emergency frequency for
possible emergency alerts and responds to them by automatically joining the emergency call.
To initiate the emergency alert, the radio must be in MS-MS DMO mode or out of coverage in TMO
mode. The alert is not sent to the dispatch console.
To receive the emergency alert, the radio must be in DMO or TMO, within RF range of the initiating
radio, and must not be in a call. When the radio receives the emergency alert, it joins the call
automatically.
The following table illustrates the dependencies between the current radio mode and the type of
emergency operation:
