what parameter is currently being edited. If there are several parameters on one screen, two of the soft
keys will be labeled
and
. These keys are used to move the cursor from one parameter to the next,
and therefore any of the configuration parameters displayed on the screen can be edited. The left arrow (
) moves the cursor to the left, and the right arrow (
) moves the cursor to the right. If the cursor is at
the beginning or end of a row containing several parameters, the cursor will wrap to the opposite side of
the display.
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.
