Alt Mode Operation
Introduction
Alt Mode lets you view and configure many of the MDR settings without using a
video monitor. Alt Mode refers to the alternate functions assigned to the front panel
numeric keys. In Alt Mode, each of these keys has three different functions called Alt
Mode 1, Alt Mode 2, and Alt Mode 3.
Operation
To enter Alt Mode, press the front panel Alt key. If the ALT LED does not illuminate,
press the Alt key again. Pressing the Alt key a second time is necessary because the
menu was on, and pressing the Alt key the first time caused the menu to exit.
After you enter Alt Mode, you can cycle through the three Alt Mode functions by
pressing the Alt key. When Alt Mode is active, the front panel ALT led is illuminated
and the front panel displays which Alt Mode function is currently selected (A1, A2,
or A3).
When you have selected the Alt Mode function you need, press the appropriate front
panel numeric key to perform the function you want.
Editing a numeric value
If you want to modify a numeric value in the Alt mode display, first enter edit mode,
then make the change to the number, and finally save the changes.
If the key has an edit mode, press the front panel Yes key to enter edit mode.
While you are making changes to the numeric value, you can move between digits
by using the left and right arrow keys.
Note: Editing a numeric value requires that each digit position be occupied by a
number. Therefore, you must enter all trailing zeros.
To save the edited field, press the Yes key.
Cycling through options
Often the displayed Alt mode field comprises one of several predetermined options.
You can cycle through these options by using the up and down arrow keys. To save
the chosen option, press the Yes key.
Exiting
To exit Alt Mode, press the View key.
