PROBLEM TO BE SOLVED: To prevent a fault of the radio equipment through a processing content of a software by allowing a microcomputer controlling the radio equipment to detect a mount state of an antenna and using the result for a condition. SOLUTION: A mechanical position 2 is moved in response to the mount state of an antenna 1 and it is transmitted to a conversion section as a mechanical signal, converted into an electric signal and delivered to a control microcomputer. Thus, the mount state of the antenna is detected by the microcomputer. As a result, when transmission is started, the transmission is conducted only when the antenna is not mounted. When it is detected that the antenna is not mounted, warning by indication and buzzer is made for the user. |
