    7.1.5 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM Function: To prevent a power-down from being generated, operation of only the digital-signal processing and audio circuits are enabled, and power is not supplied to the panel driving system (large-signal system). Usages: 1. In a case where a check is required of signals' being correctly output to the driving systems during a repair, etc. 2.

  • Page 80: Backup When The Main Unit Is Adjusted

    7.1.6 BACKUP WHEN THE MAIN UNIT IS ADJUSTED Outline Adjustment data set at the factory are stored in the EEPROM (IC****/4K) on the HD DIGITAL Assy. Those adjustment data are automatically backed up in the EEPROM (backup EEPROM: IC****) on the HD AUDIO Assy. Therefore, even if the HD 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 main unit.
  • Page 81 3. In a case where the HD DIGITAL Assy is replaced with one for servicing because of a defective EEPROM on the original Assy and manual adjustments are to be performed (In a case where no data are stored in the HD DIGITAL Assy or as backup, and the values that have been manually adjusted on Service Menu are to be applied as adjustment data for the main unit) Command: "UAJ"...
