Abstract
A small piece of electronic equipment having an initializing function to be driven by a battery has an arthmetic memory and a special check data memory. When a specific key to designate the clear processing is operated in a key input section, it discriminates the checked data stored in the check data memory by an arithmetic operating section which judges if the check data has been replaced by another. If the checked data is found to be not replaced by another in accordance with its discrimination result signal, a control signal which allows the clear processing to clear the contents of the partial memory area of the arithmetic memory is generated by control circuits. If the checked data is found to be replaced by another, a control signal for permitting initialization processing to be executed is generated.
