There are several important things to observe on the screen:
The knob icon appears at the top of the screen. The knob icon indicates that
the general purpose knob is set to adjust a parameter.
The upper right corner of the screen shows the readout High Ref: 90%.
The High Ref side menu item is highlighted, and a box appears around the
90% readout in the High Ref menu item. The box indicates that the general
purpose knob is currently set to adjust that parameter.
To adjust the high level to 80%, turn the general purpose knob.
