By using areas, it is possible to exchange messages with multiple parties.

■Provide separate recording media for recording your own messages and recording media for recording the other party's messages.

■ Stop recording the other party's message by capturing the timing when the squelch signal is turned on.

As described in detail, according to the present invention, a personal radio device is provided with a recording/playback unit, and it is possible to automatically send own messages and automatically record messages of the other party. Now, it is possible to exchange messages even if one party is not present. Also, the sending of own messages is not done immediately after switching to the communication channel, but when the other station is in the receiving state (
22) Since this is done after confirming that the message has been sent, it is possible to reliably transmit the own message to the other station, and the recording of the other party's message is started only after confirming that the other station is in the transmitting state. This has the effect of being able to reliably record the other party's message.
