Zusammenfassung:PURPOSE:To obtain a wrist type radio equipment with high performance by transmitting/receiving a signal between a wrist watch section and a pocket section by means of a radio wave using a weak radio wave and using a frequency band different from the radio wave so as to make correspondence with other station. CONSTITUTION:The transmission state is obtained when a buzzer 318 informing an incoming call buzzes, a carrier brings the mode into the radio function mode by depressing a mode button 308 and a button 305 is depressed. In speaking at a microphone 310, after a talking signal FM-modulated is demodulated once, a radio wave of 900MHz band is modulated and the result is transmitted from an antenna 316 to an opposite station. Then a reception signal of the antenna 316 is demodulated at the transmitting state of the opposite station, the signal modulates a weak radio wave, the modulated wave is transmitted from an antenna 317 to an antenna 309, where the wave is received and demodulated. In calling the opposite station, the mode button 308 is selected to the radio function mode and a group number of the opposite station is set by a key button 304. Then the weak radio wave is transmitted to a pocket 312 by depressing the button 305 so as to make transmission to the opposite station from the antenna 316.
