ABSTRACT:
A circuit arrangement for controlling the operating functions in a device such as a broadcast receiver, including an up/down counter associated with each operating function wherein a particular count corresponds to a certain setting of the operating function. Switch means coupled by a single conductor to the common inputs of two threshold-value circuits provide one of several voltages thereto which cause one or the other or neither of the threshold-value circuits to output a control signal to the up/down center, which in turn counts up, down, or remains at the same count.
