ABSTRACT:
A device has a program upgrading capability. Upon start-up, a CPU checks if an upgrading program is stored in an EEPROM, and, if stored, a main program is overwritten with the upgrading program and then the main program is started. The program generates a signal within a predetermined time after start-up, if the program runs properly. If no such signal is detected within the predetermined time, the CPU overwrites the upgrading program with a shipment state program which stored in the EEPROM.
