7.1.5 BACKUP WHEN THE PANEL UNIT IS ADJUSTED
• After the OB DIGITAL Assy is replaced with that for service, check that
“DIG. EEP: NO DATA!” is displayed on the Panel Information screen of
the Factory Menu.
• If this command is not executed, the red LED lights, and the blue LED flashes,
to warn you that copying of the backup adjustment data for the panel unit failed.
• If both the OB DIGITAL Assy and AUDIO Assy are to be replaced, first replace
the AUDIO Assy and set the unit to Standby mode. Then replace the OB
DIGITAL Assy.
• If the OB DIGITAL Assy of Unit 1 is mounted to be reused in Unit 2 to be
repaired, and Unit 2 enters Standby mode, the adjustment data and histories
stored in Unit 1 are erased, and those of Unit 2 are copied. Once overwritten,
the original data will not be restored. After the Assy is replaced, be sure to enter
Factory mode, using the remote control unit for servicing, and perform the
procedures described herein. Or, before mounting an Assy to be reused as a
service Assy, perform these procedures then mount it on the product to be
repaired.
Outline
Adjustment data set at the factory are stored in the EEPROM (IC3156/4K) on the OB DIGITAL Assy. Those adjustment data are
automatically backed up in the EEPROM (backup EEPROM: IC3754) on the AUDIO Assy. Therefore, even if the OB DIGITAL Assy is
replaced, the adjustment data can be restored by copying the backup data, which enables you to omit newly performing adjustments on the
panel unit.
Data to be backed up
• Voltage margin adjustment values
• Data on the hour meter
• Upper limit of power-adjustment value
• Data on the pulse meter
• Panel WB adjustment values
• Serial number
• Drive waveform adjustment values
• Data of the P-ON counter
• PD/SD histories
How to copy the backup data
1. When the OB DIGITAL Assy is replaced with that for service (normal servicing)
(In a case where no data are on the DIG. EEP, and backup data have been adjusted)
2. In a case where a OB DIGITAL Assy that was mounted on another unit is to be reused as a service part.
