Control Knob Operation
The control knob is used to change system configuration settings. The knob can be turned either right or left to
increase or decrease a control value such as brightness or to select one setup condition from a series of choices
such as a test pattern. For adjustments affecting the video output, turning the control knob affects the output display,
so the result of the change is instantaneous. When a system menu is displayed, turning the knob will highlight one of
many choices used to access another menu or a control parameter. When the desired choice is highlighted, pressing
the SEL key causes the display to change to the desired control function or menu. Slide bars are used to graphically
display many controls. Turning the knob will change the control parameter and also update the slide bar. Normally,
turning the knob slowly allows for fine adjustments and turning the knob quickly causes the parameter to change
more rapidly. For selections that require a choice from a scrolling list, a scroll bar is normally displayed to graphically
inform the operator of where he is in relation to the list of choices available.
