Emergency Individual Calls (Private or MSISDN)
The Emergency Individual Calls are simplex or duplex calls with emergency priority.
On pressing the
Emergency
button, your radio initiates an individual call to a provisioned private .
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, your radio rejects all incoming individual calls with non emergency
priority. These rejected calls are shown as missed calls after the Emergency Individual Calls have
ended.

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 is configured.

Emergency Hot Microphone
The Hot Microphone allows you to talk without pressing the
PTT
button during Emergency Operation.

PTT

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.

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:
