Abstract

PURPOSE:To make it possible to rewrite the preset station with a new station automatically, by causing the rise order of frequencies of stations and memory numbers of the preset memory device to correspond to each other after stations are preset in respective memories of the preset memory. CONSTITUTION:The rewrite start signal is supplied automatically synchronously with turning-off of write button 3 after stations are written into a preset memory by preset memory input means 5. Initial value set circuit 9 is controlled by the control signal supplied from preset memory device 6 and sets initial value M. The value of counter 11 is supplied to the input side of cunter information detector 12, and information except detector 12 is supplied to memory device 6. After writing the channel selection signal into the memory of device 6, preset channel selection buttons 1a-1e of the preset memory device and the rise order of frequencies of stations are caused to correspond to each other and are preset.
