ABSTRACT OF THE DISCLOSURE The operation of an electronic appliance, such as a casette tape deck, is controlled completely or partially by switch operation. The appliance includes a memory for storage of control information, setting devices, such as switches, for entering the control information, a memory lock or latch for controlling the operating state of the appliance based on the control information supplied from the memory or from the setting devices to the memory lock, and for locking the appliance into such operating state, a display arrangement adapted for display of the setting information and for display of the information in the memory lock, and a setting change display indicator. The setting information stored in the memory can be checked by actuating a check switch, which causes the setting information stored in the memory to be displayed without affecting the operating state in which the appliance is locked. When the operating state is changed by a setting operation while the information previously stored in the memory has been transferred to the memory lock to control the operating state of the appliance, so that the contents of the memory lock (i.e., the operating state in which the appliance is locked) are not coincident with the corresponding information stored in the memory, the fact of such change is displayed on the setting change display indicator. This notifies an operator that the information is being changed, and assists the operator in avoiding unintentional errors.
