Numeric Input
You can enter numeric values by using either the numeric keypad or the general
purpose knob. If the side menu item displays a value, you can alter this value
using the general purpose knob or numeric buttons.
Pushing the type of side menu button or selecting a parameter in a pop-up menu
causes the current setting to appear on the right end of the Status Display area as
shown in Figure 2–5.

Underscore
Figure 2-5: Knob icon displayed in Status Display Area
A knob icon with a numeric value that includes an underscore character indicates
that you can change the value by using the general purpose knob or keypad
buttons.
If the numeric value has the knob icon, but does not have the underscore, then
turning the general purpose knob cycles through a predefined set of values.
By default, the underscore character is positioned under the digit specified
depending on the parameters. You can only change the value represented by the
digits at and to the left of the underscore. Use the a and ' arrow buttons to move
the underscore to the desired position and then turn the general purpose knob to
change the value.
When using the general purpose knob, values you change in side menus and
menu screens take effect immediately: values in pop-up menus are not effective
until you push the OK side button or the ENTER front-panel button.
