PURPOSE:To simplify the operation extremely, by providing a tuning operation section to a wrist watch, and tuning a headphone type radio receiver. CONSTITUTION:In figure, 34 is a block generating a signal for the tuning of a radio receiver and a logic circuit converting an instruction for tuning given from a push button 24-1 or 24-2 into a signal form suitable for remote control transmission. The tuning instruction transmitted from the wrist watch is given to tuning buttons 6-1, 6-2 of the headphone type receiver and an OR circuit 42 and when any instruction is given, this starts an up/down counter 12 for tuning control. Further, the output data of the counter 12 controls a PLL circuit 14 similarly for the tuning of the receiver 20. |
