Interface Dial
Most audio system functions can still
be controlled by standard buttons,
dials, and knobs, but some functions
can only be accessed using the
interface dial. The interface dial has
two parts, a knob and a selector.

select menus, and to highlight menu
items. When you make a selection,
push the center of the selector
(ENTER) to go to that selection.
