2. When a secondhand DIGITAL Assy that had been mounted in another product
is to be reused
As adjustment data for another product are already stored in the secondhand DIGITAL Assy, first delete those data then copy
the backup data stored in the EEPROM on the SENSOR Assy.
(1) Copying, using the Factory menu
1 Plug in the AC cord, press the Power switch on the unit to set it to ON, then enter Standby mode.
2 Turn on the power, using the remote control unit, then enter Panel Factory mode.
Copy the backup data, as shown in the figure below.

3 Turn the power off.
Note:
If the secondhand DIGITAL Assy is mounted in the product then the unit is turned on then back off again, the data in the
EEPROM on the DIGITAL Assy are copied over the EEPROM in the SENSOR Assy. Thus the backup data can never be
restored. During the first power-on after the DIGITAL Assy is replaced, be sure to enter Factory mode to copy the backup
data. Or, before removing the secondhand DIGITAL Assy from the original product, delete the adjustment data on it, using the
E
Factory mode (DIGITAL EEPROM: DELETE), mount it to the product to be repaired, then copy the data from the backup
EEPROM.
(2) Copying, using the RS-232C commands
1 Switch the RS-232C/SR+ setting to RS-232C so that RS-232C commands can be received.
2 Turn on the unit, using the remote control unit or by issuing the PON command. Then issue the FAY command.
3 Issue the UAJ command to delete data stored in the EEPROM on the DIGITAL Assy.
4 Issue the BCP command to transfer the data stored in the EEPROM for backup.
5 Turn the power off.
