PURPOSE:To facilitate channel setting operation by producing a channel code by the oscillation of an oscillator, and storing and holding the channel code in the storage means of a receiver. CONSTITUTION:When a channel registration switch S is pressed while the oscillator selects a channel to be held in the receiver, channel codes appearing at (a), (b), (c), and (d) of a decoder circuit 6 are held in a flip-flop 9. Once channel codes are registered in the flip-flop 9, information on the kind of a channel appears at (a)-(d) of the decoder circuit 6 when the oscillator performs channel selection and control, and the information is compared with channel codes (a')- (d') registered by a coincidence detection circuit 7, so that control information (j) is held by the flip-flop 8 and outputted when a coincidence is obtained. |
