  • Publication number: 20240056118
    Abstract: A device state detector of a given device detects a device state and outputs it as device state information in association with whether it is a transmission standby state. A transmitter transmits a radio wave for a transmission voice signal and the device state information. A receiver outputs a received signal to a signal processor that decodes it into a reception voice signal and device state information of a counterpart device. A recorder records the transmission and reception voice signals. A memory unit stores the pieces of device state information of the device and the counterpart device. A recording determination unit determines whether to continue or stop recording by the recorder. The recording determination unit determines to stop recording if both of the devices are not in a transmission standby state at the time of termination of transmission or reception of a radio wave for the voice signal.
