(‘--->‘) 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 softkeys 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
move 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 softkeys with the desired values. In cases where there are multiple parameters shown on
a screen, the values are edited with the softkeys and loaded by pressing the ENTER key, which
also advances to the next screen in the menu tree. Pressing the softkey 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 softkey 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 softkey labeled ‘NEXT’, which will advance to the next screen in the menu tree and so on.
3.5.2.2 Moving to the Next Screen in a Menu Tree
If the user desires to advance to the next screen in the menu tree, the softkey labeled ‘NEXT’
should be pressed. Some submenu screens can only return to a previous screen, in this case a
softkey 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.
3.5.2.3 Moving to the Previous Screen in a Menu Tree
If the user desires to advance to the previous screen 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.
3.6 Summary of Basic Front Panel Controls

CLEAR Aborts loading values into memory and moves to the previous screen in the menu tree.
NEXT

3.7 DMD10 Modem Strap Codes (Quick Set Keys)
The Strap Code is a quick set key that conveniently sets many of the modem parameters. For
quick setup of the DMD10, Strap Codes are very helpful. When a Strap Code is entered,
