When focus gain remains at initial value and tracking gain
changes, fault exists before ADSC input.
When focus gain changes and tracking gain remains at initial
value, fault exists after ADSC output.
[Tracking system]
When focus gain remains at initial value and tracking gain
changes, fault exists after ADSC output.

coded binary data.
2. DSL offset learned value is effective only in upper 2 digits. (Lower
