PROBLEM TO BE SOLVED: To provide a mobile telephone system which degenerates operation of a mobile telephone device in the vicinity of a man having a transmitter and an apparatus in which a transmitter is set, and restrains radio communication operation. SOLUTION: The mobile telephone device 10 is provided with a detection signal transmitting part 32 for transmitting a detection signal produced by a detection signal producing part 31, a receiving signal discriminating part 34 for discriminating a response signal from the transmitter 40 which signal is received by a signal receiving part 33, a warning output part 21f for generating warning information, and an operation degenerating part 21g for degenerating operation of the mobile telephone device 10. The transmitter 40 is provided with a signal converting part 42 for producing a response signal corresponding to a detection signal from the mobile telephone device 10 which signal is received by a signal receiving part 41, and a signal transmitting part 43 for transmitting the response signal to the mobile telephone device 10. When the mobile telephone device 10 receives the response signal from the transmitter 40, the warning information is generated by the warning output part 21f, and operation of the mobile telephone device 10 is degenerated by the operation generating part 21g, thereby restraining radio communication operation.
