A method and device for renewing an internal program of an apparatus having communication capability.

摘要

A method and device of renewing an internal program of an apparatus communicatable with a central station operable to transmit a new apparatus control program. It is judged 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. <IMAGE>
