Main Knob
The various functions of the larger “Main” knob depends on the active mode of
the system. To move through the range of available settings for a particular con-
trol, rotate the knob. For example, the Main knob can be used to move frame-
by-frame through a loop.
The Main knob also controls one or two separate parameters per mode. Press
the knob down to activate the different parameters.
For example, in
PW

the bottom center of the screen display the two choices with Gain highlighted as
the active default control. Press the knob to select Volume; press the knob
again to re-select Gain.
Use the Main Knob to scroll up and down when the Patient Report is displayed.
