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 the Back touch icon 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 Back 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.
• The PTT button is pressed (if configured).
NOTE: When the radio goes out of the service, it enters the reception phase and the Alternating
Hot Microphone is on hold. When the radio is back to the service, the Hot Microphone
transmission and the Alternating Hot Microphone resume.
When you are in the Emergency Mode, pressing the Emergency button restarts the Alternating
Hot Microphone.
3.5.8
Invisible Emergency
Your service provider can disable visual and audible indications on the radio in Emergency Operation.
This feature is called Invisible Emergency. Invisible Emergency provides an extra layer of safety when
using Emergency Operation in critical situations. Critical situations are such as a direct attack on the
user.
