 shaded items are fixed data.

•

Standard data listed on the Adjustment Item Table are reference values, therefore it may be different for each model and for each mode.

•

Note for Different Data

Those are the standard data values written on the microprocessor. Therefore, the data values of the modes and stored respectively in the
