Hot Microphone Function In the Hot microphone state, only microphones whose PTT switch is pressed can send modulation signals in the environment in which several microphones are connected to the transceiver in parallel. In the Normal microphone state, if the PTT switch on one of the microphones is pressed, modulation signals are sent from all microphones.
