Abstract
A control signal generator is provided to supply a control signal to a control unit of a telephone set having dial memories. Information stored in a memory in the dial memories is forbidden to be erased, unless the control signal is supplied to the control unit. As a result, important information is protected from erroneous erasing in the dial memory.
