On the peripheral device, any of only the notch frequencies "00" to "07" can be set
as the notch filter selection of the MR-J2-B.
(Since the setting is made as the MR-J2-B, the screen display differs from the above.)
On the peripheral device, the notch depth cannot be set. (It is set to the initial
setting "0".)
When setting any of notch frequencies "08" to "1F" and notch depths "1" to "3", set
this parameter in the sequence program.
