Editing a configuration parameter value is accomplished in one of several ways. If the parameter
is numerical, the desired value should be entered from the numeric keys. Occasionally, the
numeric values can be incremented and decremented by pressing soft keys labeled 'UP' and
'DOWN' respectively. In either case, when all of the numerical parameters have been edited to
the desired values, pressing the ENTER key will execute a load of the parameters into memory,
and then advance to the next screen in the menu tree. Pressing the CLEAR key will not execute a
load of parameters into memory (the original parameter values before editing will be retained),
and then advance to the previous screen in the menu tree.
If a parameter has a non-numeric value, the allowed values for that parameter can be edited by
pressing soft keys with the desired values. In cases where there are multiple parameters shown on
a screen, the values are edited with the soft keys and loaded by pressing the ENTER key, which
also advances to the next screen in the menu tree. Pressing the soft key labeled 'NEXT' or
'PREVIOUS' will abort loading the parameters into memory, and advance to the appropriate
screen. In cases where there is a single parameter shown on a screen, pressing the soft key labeled
with the desired value will immediately load the parameter into memory. In this case, the
parameter load can be aborted by pressing the CLEAR key, which will return to the previous
screen, or by pressing the soft key labeled 'NEXT', which will advance to the next screen in the
menu tree.

Moving to the Next Screen in a Menu Tree
If the user desires to advance to the next screen in the menu tree, the soft key labeled 'NEXT'
should be pressed. Some submenu screens can only return to a previous screen, in this case a soft
key will be labeled 'RETURN'. In either case, if any numerical parameters are being edited, the
values will not be loaded into memory. When the last screen of a menu tree is reached, advancing
to the next screen will wrap to the first screen of the menu tree.
4.2.9.3
Moving to the Previous Screen in a Menu Tree
If the user desires to return to the previous screen from a Subscreen in the menu tree, the CLEAR
key should be pressed. If any numerical parameters are being edited, the values will not be loaded
into memory. If the clear key is pressed while the first screen of a menu tree is displayed, the
previous screen will wrap to the last screen in the menu tree.
