4. Entry knob The Entry knob is used to select items from menus and to change values. The function of the
Entry knob changes based upon the current menu and softkey selections.
Note that the curved arrow symbol above the entry knob illuminates whenever the entry
knob can be used to select a value. Also, note that when the Entry knob symbol appears
on a softkey, you can use the Entry knob, to select values.
Often, rotating the Entry knob is enough to make a selection. Sometimes, you can push the
Entry knob to enable or disable a selection. Pushing the Entry knob also makes popup menus
disappear.
