Abstract

PURPOSE:To perform the reception operation accurately without causing malfunction, by providing a means for correcting iiput data to a normal reception frequency data, if the inputted data is not normal reception frequency data. CONSTITUTION:When reception frequency data is inputted by a key input means 3, a control circuit 1 discriminates whether the inputted data is within the frequency range of an intermediate wave or not, and if the data is outside the range, an error indicating lamp 10 illuminates. When the data is within the range, after the input data is fetched to a register 5, the arithmetic of the input data is made at an arithmetic circuit 4, the quotient is stored in a register 6 and the residue is stored in a register 7. Through the degree of the residue, the correction is made to the closest normal frequency data.
