ABSTRACT:
An appliance including a digital programming device for forming a sequence of control signals. When the device is switched on by way of the power supply plug, an unpredictable switch-on phenomenon occurs and the program memory is liable to be addressed in a variety of locations. Therefore, during a preparation routine the start conditions are realized. Furthermore, a multi-bit code is generated and stored in a volatile section of the memory. The operative routine comprises a sub-routine which tests this code. If the code is not correct, the preparation routine has not been followed when the appliance was switched-on. The operative routine is then interrupted and first the preparation routine is executed. All further locations in the non-volatile memory section preferably refer to the preparation routine.
