After exiting from Non-Tactical Emergency, the radio returns to the previously selected talkgroup.
3.5.4
Emergency Individual Calls (Private or MSISDN)
The Emergency Individual Calls are simplex or duplex calls with emergency priority.
On pressing the Emergency button, the radio initiates an individual call to a provisioned private or
Mobile Station Integrated Services Digital Network (MSISDN) address.
This feature also supports the direct or hook dialing method on simplex and duplex calls. For full
duplex Emergency Individual Calls initiated to an MSISDN address, the default dialing method is
configured to hook. This default dialing method cannot be modified.
In Emergency Individual Calls, the radio rejects all incoming individual calls with nonemergency
priority. These rejected calls are shown as missed calls after the Emergency Individual Calls have
ended.
Emergency Full Duplex Private Calls (FDPC) supports high/low audio state. The audio state is
configurable. You can select the audio state during incoming or outgoing emergency FDPC by toggling
hi or low audio during active Emergency FDPC.
3.5.5
Emergency SDS Status
The radio sends a status message with a preprogrammed value to the destination address set by your
service provider. Emergency SDS Status is available in TMO only. If no status acknowledgment or
negative acknowledgment is received, the radio retries sending the message. Status is not resent
when Emergency Alarm or Hot Microphone is configured.
3.5.6
Emergency Hot Microphone
The Hot Microphone allows you to talk without pressing the PTT button during Emergency Operation.
The transmission continues for a provisioned amount of time. If configured, pressing the PTT button
before the Hot Microphone time expires ends the Hot Microphone operation. Then normal PTT
operation in Emergency group call takes over whereby the transmission is ongoing for the time the
PTT button is held.
Subsequent Emergency button presses during the Emergency Operation restart the Hot Microphone
transmission.
If a talk permit is granted to another member of the group, the Emergency Call received tone is played.
If configured, the radio automatically attempts to get talk permit again.
Pressing End soft key or End key ends the Hot Microphone operation.
3.5.7
Alternating Hot Microphone
The Alternating Hot Microphone is an enhancement of the Hot Microphone. After activation, the radio
alternately enters transmission phases (your microphone is active) and reception phases (you can only
listen) for an amount of time precisely determined by your service provider.
If this feature is enabled, you can initiate the Alternating Hot Microphone by pressing the Emergency
button. If you want to finish earlier or skip the transmission phase, press the End key.
The Alternating Hot Microphone terminates when one of the following conditions is met:
• The radio exits the Emergency Mode.
• The Alternating Hot Microphone timer expires.
