Abstract
PURPOSE:To make the operation at the setting of reception frequency easy, by providing a means inputting a reception frequency, comparing the inputted frequency with the frequency band which is receptional, and setting the frequency unit and the band. CONSTITUTION:A frequency display device and a frequency storage device 27 are cleared, and when the numerical key 12 is inputted, the corresponding numeric data is set to the storage device 27, and simultaneously the set content is displayed on a display device 9 by a gate and buffer circuit 21 through register 22 and 23. The lower and upper values of the frequency band of each band programed in advance in an ROM31 are transferred to a frequency band storage section 28, and they are compared with the content of the storage section 27 at every band of LW, MW, SW, and FM. If they are outside of the band frequency, the content of the storage section 27 is corrected by the software so that the decimal point is in kHz unit and no digit is preset below the decimal point.
