Abstract
Abstract A system for prescribing one of a plurality of possible operating conditions for a radio device is disclosed wherein a punched card containing coded information identifying selected ones of the plurality is optically read in a static manner and the thus read information utilized to energize a visual readout identifying which of the several possible operating conditions has been defined by the specific information read from the card and the thus read information is also used to cause the system to operate under the prescribed operating condition. In the embodiment described, the condition is the frequency at which a transmitter and/or receiver is to operate.
