3.6.4 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.

3.6.5 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.
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.
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.

3.6.6 Alternating Hot Microphone

The Alternating Hot Microphone is an enhancement of the Hot Microphone feature. It allows you to have the Hot
Microphone switched on and off alternately.
If this feature is enabled, you can initiate the Alternating Hot Microphone by pressing the EMERGENCY button.
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.
• End SOFT key is pressed (only during transmission time slot).
To skip your transmission time slot and jump to a receiving time slot, press END key.
When the radio goes out of the service, it enters the receiving mode 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.
