PROBLEM TO BE SOLVED: To surely transmit the telephone number of a present station to an opposite station by simple constitution by reading the telephone number data of the present station from a storage part by the operation of an instruction button, converting them to voice signals and radio-transmitting them to an opposite station telephone set. SOLUTION: When a command for instructing the transmission of the telephone number of the present station is sent from an operation part 6, a CPU 7 reads the telephone number numerical values of the present station stored inside a ROM 9a, displays them at a display part 11 by a driving part 10 and reports that it is under transmission to the opposite station. Simultaneously, the CPU 7 performs control for converting numerical data to the voice signals by the ROM 9b, modulating the voice signals in a modem part 12, converting them to a radio frequency, amplifying the signals by a transmitter-receiver 13 and sending them out through an antenna 14. Further, the control is performed so as to drive a speaker driving part 15 by the voice signals and to make an operator able to confirm the telephone number of the present station by voice as well. Thus, the telephone set of the opposite station does not require the display part and a special hardware for receiving and reproducing PB signals and is simplified.
