button, perform automatic correction of central frequency of a notch filter, display register setting after automatic
correction and a frequency characteristic (Figure 19). This automatic correction is valid for a Equalizer Band which is
set its gain to "-1".

correction is not performed properly. Please confirm a correction result by indication of a frequency characteristic.
