PROBLEM TO BE SOLVED: To speedily execute communication between a maser machine and a slave machine after an opposite party is called with optimum transmission power without distortion in transmission data. SOLUTION: In a radio communication system 1 provided with a facsimile equipment 4 and the telephone slave machines 6-8, frequency data of use frequency on the transmission power levels of three stages, which are used for the past radio communication whose number of times is the largest, are accumulated and stored in a frequency data storage part provided for the facsimile equipment 4. Frequency data of use frequency on the respective transmission power levels of three stages, which are used for the past radio communication whose number is the largest, are accumulated and stored in frequency data storage parts provided for the telephone slave machines 6-8. Since the facsimile equipment 4 uses the transmission power level whose use frequency is the largest or the telephone slave machines 6-8 use the transmission power level whose use frequency is the largest, the call is speedily made with optimum transmission power without distortion after the opposite party is called.
