<p>PURPOSE:To change a set numerical value in the digital switch system to improve the operability and to prevent a failure in setting by displaying an input setting key frame in a position which is not included in a set item part or a numerical value display part on a display screen. CONSTITUTION:An input setting key frame 1 is provided with an input data display part 2, which has digits whose number corresponds to a maximum number of digits of a numerical value display part 15, and increase keys 3 and reduction keys 4 which correspond to respective digits of the display part 2, and this key frame 1 is not displayed in the normal display state. When a display part 15 of some set item part 14 is touched in case of data setting, the display ion the selected display part 15 is flickered and the frame 1 is displayed in the position which is not included in the item part 14 to be selected or its display part 15 on the screen, and input is possible. The same numerical value as the selected set numerical value is displayed on the display part 2 in the frame 1, and the set numerical value is directly increased or reduced by touch to the key 3 or the key 4 corresponding to an arbitrary digit in the frame 1 to set and change the numerical value; and thus, the operability is improved and a failure in setting is prevented.</p> |
