The Multipurpose knob lets you interact with on-screen menus, messages, and dialog boxes.
A icon on a menu, message, or dialog box label means that you can use the Multipurpose knob to select and click
values in that item.
The turn arrow indicator, located below the knob, turns green when you can use the knob to make selections or enter
values in a menu or dialog box.
The knob has two functions:
• Select function, where you turn the knob to select (highlight) a menu item. Selecting a menu item does not execute
(run) that function.
• Click function, where you push the knob to either run the selected menu item or enable a field in that menu item to
enter numbers or select values.
