PURPOSE:To simplify the operation of inputting again in the case of erroneous inputting when inputting the figure of N digits one by one, by replacing the input figure from the first digit as a reinputting when N+1th input figure is specified figure. CONSTITUTION:A signal processing circuit that inputs the figure of five digits that indicates frequency to be set to a channel selecting circuit 15 stores a figure inputted from key matrix 21 once in a figure register 31 and then stores successively to a digit indicated by the digit register 32 of a frequency register 33. When an ENTER key is inputted by sixth inputting, the numerical value of the frequency register 33 is transmitted to a nonvolatile memory 34 and the channel selecting circuit 15. When a figure key is inputted and the figure is a specified value (1 when 11,700GHz-12,200GHz is selected), it is judged as the reinputting for correcting erroneous operation, and the storing is made again from the first digit of the frequency register 33.
