Procedure 2
Remove the EEPROM from the board of the machine that is going to be repaired.  Install the removed EEPROM
to the replaced board.
Procedure 3
When the data cannot be saved due to defective EEPROM, or when the EEPROM cannot be removed or
installed, save the data from the same model of the same destination, and download it.
After the EVR data is saved and downloaded, check the
respective items of the EVR data.
(Refer to page 6-3 for the items to be checked.)
