A cursor below a text or numerical value shows what is affected by
the dial. To increase the value turn the dial clockwise. To decrease
the value turn the dial counterclockwise. The value can be reset by
turning the dial several clicks counterclockwise.
When setting numerical values the cursor moves up to the next digit
if the dial is turned quickly in one direction (22.0), to simplify
entering large values. The cursor moves back one place to the right
every two seconds if the dial is not turned. The text or numerical
value displayed is accepted by pressing the OK-button. To cancel,
press the ESC-button.
