Outline
Adjustment data are stored in the EEPROM (IC3156/4K) on the DIGITAL Assy in the production process. Those adjustment
data are also automatically stored in the EEPROM (for backup: IC3652) on the SENSOR Assy.
If the DIGITAL Assy is replaced, those adjustment data for backup can be copied from the EEPROM on the SENSOR Assy to
a new DIGITAL Assy.
Backed up data
• Drive voltage adjustment value
• Hour-meter count
• Pulse-meter count
• Panel white balance adjustment value
How to copy backup data
1. When the DIGITAL Assy is replaced with one for service (usual service)
Adjustment data can be restored by copying the data backed up in the SENSOR Assy to the EEPROM on a new DIGITAL
Assy.
The EEPROM on the new DIGITAL Assy has no adjustment data, and the EEPROM for backup in the SENSOR Assy has
adjustment data.
• Copying, using the RS-232C commands
1 Enter Module Adj. (Refer to "8. MODULE ADJUSTMENT MODE")
2 RS232C command "FAY"is performed.
3 Issue the BCP command to transfer the data stored in the EEPROM for backup.
4 Turn the power off.

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.
• Copying, using the RS-232C commands
1 Enter Module adj.. (Refer to "8. MODULE ADJUSTMENT MODE")
2 RS232C command "FAY"is performed.
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.
3. In a case where normal backup data are not stored in the backup EEPROM because
the EEPROM on the DIGITAL Assy is defective, etc., and where manually adjusted
values are to be applied to the product
Note: In this section, it is assumed that settings for various items have been completed, using RS-232C commands.
• Method using the RS-232C commands
Issue the FAJ command.
