Invisible Emergency
It is possible for the service provider to disable visual and audible indications when performing
Emergency Operation on the radio, known as Invisible Emergency. Invisible Emergency provides an
extra layer of safety when using Emergency Operation in a critical situation, for example during a direct
attack on the user.
3.5.10
Emergency Alert
This feature allows the radio to send emergency alerts to other radios within its DMO coverage by
pressing the Emergency button. Even in TMO mode, 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:
