Click the "AN Setting" button of the desired channel on the Main (FISHBONE) view screen.
Settings are possible for channels using the AN-001T module. The selected button is highlighted.
Check the "AN ON" checkbox on the displayed AN setting screen, and the setting items become valid.

Clicking the “GET LEVEL” button displays the AN reference level in the Reference Level box.
Using the ANC ADJUST combo box, adjust the ANC adjustment value so that the reference level becomes
"0." Increase the ANC adjustment value when the reference level is higher than 0, and decrease when it is
lower than 0.
Click the ADJUST button, and the set value is stored in the amplifier. Repeat this procedure from the
beginning until the reference value becomes nearly “0.”
