ABSTRACT:
A method and device for renewing an internal program of an apparatus capable of communication with a central station operable to transmit a new apparatus control program. It is determined whether data received from the central station is a new program. Replacement is then executed of a previously stored program with the new program, if a new program is received. A previously stored internal program is automatically overwritten by a new program transmitted from the central station.
