Abstract
A first device having a segmented display for normally displaying information in numeric or alphanumeric form is provided with means to aid the setting of a bank of externally accessible switches on a second device so that they correspond with internal switching data contained in the first device. Segments or groups of segments on the display of the first device are selected in pairs to represent a position of a respective switch on the second device. One of each pair of segments or groups of segments is activated so that the appearance of the display corresponds to the desired appearance of the properly set switches in the bank of switches. This aids in setting the switches to the proper positions. For example, each pair of vertically aligned segments in a segmented numeric display represents a switch position. The switch is set on or off depending upon whether the upper or lower segment of each vertical pair is activated. Although not so limited, the invention finds application in setting the external bank of switches in a radio receiver to correspond to a transmitted code signal in a radio transmitter, where the transmitter code switch setting may not otherwise be visible.
