(*1): These parts have not been mounted.
(*2): It is recommended to measure the DAC output voltage with the drive off.
(*3): View when the Assy is mounted on the unit and viewed from the rear.
(*4): The value calculated using an adjustment value may be different from the
value measured at the last output stage, because various corrections such
as temperature correction are not taken into consideration.
