Abstract

PURPOSE:To automate the preset work, by the automatic search of the frequency band and the preset of the electromagnetic waves of a plurality of broadcast stations having the strength of electric field more than the specified level to the channel selector after catching them sequentially. CONSTITUTION:When the automatic preset key is depressed, the instruction of the automatic preset is transmitted to the center control logic 26 through the function key logic 23. Further, the instruction goes to the memory 30 and data output logic so that the searching can be made from the band edge of lower frequency to the higher to start the search for the tuner. If the broadcast station to be received is present, the automatic stop trigger circuit 13 is operated and instruction is made so that the search is stopped to the center control logic 26 through the scanning stop control 37. Further, the instruction is given to the data key logic 22 so that the preset can be made to the 1st channel. When the preset is finished, the search is again started, similar procedures are repeated, and search is stopped when the frequency reaches the higher band edge.
