Sending An Emergency Call With Hot Mic (Trunking
Only)
This feature allows you to send an Emergency Call with hot mic to a group of radios.
When and where to use:
Your radio must be programmed for this type of operation.
Your radio microphone is automatically activated, allowing you to communicate with the group of radios
without pressing the PTT button. This activated microphone state is also known as hot mic. The hot
mic applies to the first voice transmission from your radio during the Emergency call. For subsequent
transmissions in the same Emergency call, you must press the PTT button.
When indirect PTT such as Hot Mic is activated, the audio transmission can be configured in CPS to route
the audio to the radio internal microphone, wired RSM microphone, or Bluetooth wireless microphone.
