のパーソナル無線機において、 前記警告動作手段は、警告信号に基づいて音声
を出力するものであるパーソナル無線機。[Scope of Claim for Utility Model Registration] (1) In a personal radio device that modulates and transmits an audio signal output from a microphone while a press talk switch is operated on the transmitting side, in response to a transmission instruction signal. a control signal output circuit that outputs a control signal and outputs a transmission end signal after outputting the control signal; and when a control signal is given from the control signal output circuit, switching from audio signal transmission to control signal transmission. Based on the switching circuit and the operation output when the pre-talk switch is operated on the transmitting side, a timing signal corresponding to the timing at the time of the operation and the timing at fixed time intervals during transmission is formed, and this timing a timing signal generation circuit that outputs a signal as the transmission instruction signal; and a timing signal generation circuit that outputs a warning signal indicating that audio transmission is impossible between when the transmission instruction signal is applied and when the transmission end signal is applied. 1. A personal wireless device comprising: a warning signal output circuit; and warning operation means that performs a warning operation based on the warning signal. (2) The personal radio device according to claim 1 of the utility model registration, wherein the warning operation means outputs a sound based on a warning signal.
