Abstract
PURPOSE: To make effective use of the unit for home use receivers and car radios, by making easy the confirmation of preset operation, through long or short operation time of the preset switch for preset operation.
CONSTITUTION: When the user depresses either of the preset switches 1-1, 1-2... to perform preset, if the switch depression time (a) is longer than the time constant T1 of the monostable multivibrator 12, the multivibrator 12 is reset (b) at time t1, AND gate 14 produces output (d), and the operation of memory 3 is at write=in operation. Simultaneously, since the audio output (e) of the receivers 6∼8 is in muting by time T2(T2=T3-T1, where; T3 is the time constant of the monostable multivibrator 13), the user can know the end of preset and sure preset can be made detouching the switches 1-1, 1-2....
