The tape recorder operates on a cordless remote-control unit at remote distances from basic unit by means of control switch (record, play basic, rewind, fast forward, stop) attached to the remote unit. This arrangement provides a remote control record/play back cordless telephone to record and play back the speech content in the remote unit while the opposite party is on the telephone or before the speaking begins. The remote unit includes a digital encode circuit that converts the signal of a selected function for control switch into a digital signal corresponding to the selected function, FM-modulates and amplifies said digital signal, and then cordlessly transmits it to base unit.
