Abstract

PURPOSE:To change a frequency rapidly and accurately, by selecting an optional digit, where a number should be entered, by a keyboard to replace only the number of this digit. CONSTITUTION:When the operation key of a keyboard 4 is depressed, the most significant digit of a frequency display equipment 3 is flickered, and entry of a number with which the number of this digit is replaced is permitted. When the operation key is depressed again, the next lower digit is flickered, and thus, a desired digit where the number is replaced is flickered. When a number with which the number of the flickered digit is replaced is entered, the number of this digit is replaced, and the next lower digit is flickered.
