Silent Emergency Mode

The Silent Emergency Mode is a type of emergency services that provides no audible indications nor
keypad tones at the entrance. All the display indications are as in the home mode. However, the radio
cannot use any services except for:
• Receiving Ambience Listening
• Sending Silent Emergency Alarms
• Sending GNSS location reports
NOTICE: The radio blocks any other feature that you try to activate.
If the Silent Emergency feature is enabled, the radio enters Silent Emergency Mode on pressing the
Emergency button. After entering this Mode the radio stays in TMO or switches to it, depending on the
actual state. Once in TMO, the radio sends Silent Emergency Alarm.
NOTICE: If the radio is in a private or group call, the radio waits until the call ends and then
enters the Silent Emergency Mode.
The radio keeps re-sending the alarm until successful sending is confirmed. After the alarm is
successfully delivered, the radio stays in Silent Emergency Mode and waits for the Ambience
Listening.
Your radio exits the Silent Emergency Mode, under the following conditions:
• Press Menu and then # key within 3 seconds.
• Press 1 and 3 keys simultaneously.
• No success in sending the Silent Emergency Alarm and the maximum number of retries has been
reached.
• The control room terminates the Silent Ambience Listening.
• The Ambience Listening is disconnected due to another reason.
If you turn off the radio in the Silent Emergency Mode, the radio switches to pseudo power off state. In
this state, the radio appears to be turned off. However, the radio is still on and in the Silent Emergency
Mode. On turning the radio on during the pseudo power off state, the radio acts as during turning on
and still is in the Silent Emergency Mode.

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.
