Movement Inside Menus
F1 through F12: Select the menu that corresponds to the function
key. Depending on your keyboard, there will be another key,
either F13 or the Print Screen key (on the EPC keyboard)
available to access the “EXEC” menu. These keys are always
active within Setup. The keys are labeled at the top of each
menu.
Cursor Control Keys ( ↑ ← ↓ → ): These keys control movement to
parameters within the menu and is indicated by a highlighted
selection bar. This selection bar will wrap to the other side of the
menu at the top, bottom and side boundaries. For each
parameter there are at least two choices. As the parameter is
highlighted, the available choices appear in the area above the
help bar.
Some parameters are action fields and have no choices. See
the Action Fields section later in this chapter.
Enter and Shift-Enter: Cycle “up” or “down” through the choices for a
given parameter.
The following keystrokes are also available but are not
documented in the Setup help bar.
Tab and Shift-Tab: Move from menu to menu forward or backward
without using function keys.
Space and Shift-Space: Cycle through the list of choices. Same as
Enter and Shift-Enter.
Parameters that are changed are executed as soon as that field is
exited. Page resets may occur when certain choices are made in
Setup.
Action Fields
Certain parameters are not selections but action fields. When
the action field is highlighted and then selected, the action is
taken. A “WAIT” message may appear at the top right portion of
the screen, and when the action is completed, a “DONE” message
