5-4 EEPROM Data Backup and Write
Perform this work whenever you replace the MAN circuit board on which the EEPROM is mounted. Create a backup �le of the data in EEPROM to be replaced in a PC, and write the backup �le to new EEPROM: Some adjustment items that are performed after replacement can be omitted. Refer to �6-3-2 List of Adjustments Needed After Replacing Major Components� for adjustment items that can be omitted. Information: It may be impossible to back up the data in EEPROM to be replaced, depending on the status of fault: In such a case, replace the MAN circuit board, and then perform �6-4-1 Initial Data Write�.
