that was selected before initiating the non-tactical call. When in non-tactical Emergency Mode, you are
not able to switch talkgroups. DGNA messages have no impact during non-tactical Emergency Mode but
only after exiting the non-tactical Emergency Mode.
• Tactical — call on the currently selected talkgroup.
In TMO, if the radio enters Emergency Mode while the Emergency Broadcast Call is active, the radio continues
on the call without initiating any calls and sends an Emergency Alarm. The behavior depends on your service
provider settings.
In DMO, Emergency Group Calls through a gateway are supported.

3.6.4 Emergency Private Call

The Emergency Private Calls are Simplex or Duplex Private Calls with emergency priority. On pressing the
EMERGENCY button, the radio initiates a Private Call with emergency call priority to the provisioned address. No
Emergency Alarm is sent and your radio does not enter the Emergency Mode. This pseudo emergency state (all user
indication and rejection of other services) ends as soon as the Emergency Private Call ends.

3.6.5 Emergency MS-ISDN Call

The Emergency MS-ISDN calls are simplex or duplex telephone calls with emergency priority. On pressing the
EMERGENCY button, your radio initiates an Emergency MS-ISDN call to the predefined MS-ISDN number.
The MS-ISDN call type (simplex or duplex) is predefined by your service provider.

3.6.6 Emergency Alarm

The Emergency Alarm is a special status message sent to the infrastructure on entering the Emergency Mode. The
radio may wait for infrastructure acknowledgment for this alarm and attempt retries.
Each time the radio enters the Emergency Mode, it sends an Emergency Alarm. When an Emergency Alarm is sent
successfully, your radio plays Emergency Alarm Sent tone. Due to absence of the delivery confirmation in DMO
Mode, Alarm Sent information confirms only sending the alarm.
In addition, once the radio is in the Emergency Mode on pressing the EMERGENCY button, an additional
Emergency Alarm is sent. The message can be dispatched both in TMO and DMO Modes.
Your service provider can disable the Emergency Alarm feature.

3.6.7 Hot Microphone

The Hot Microphone allows you to talk without pressing the PTT button on entering the Emergency Mode. The
transmission continues for a provisioned amount of time.
This feature can be enabled for the Private Emergency Call.
Pressing the PTT button before the Hot Microphone time expires ends the transmission. Then normal PTT operation
takes over (that is, the transition is ongoing for the time the PTT button is held). Subsequent EMERGENCY button
presses during the Emergency Mode initiates the Hot Microphone transmission again.
