Abstract
The program code of an object program of a radiotelephone is recorded into a RAM (3) rather than in an EPROM as is conventional. The checking of the program code and the loading of the program from an external device coupled thereto via an external bus is controlled by program recorded in a ROM (4). This allows the program code to be changed and updated as required with time consuming and expensive replacement of a whole memory.
