Entering Field Values With The Keypad; Toggle Field Editing; Using Hot Keys - Aeroflex NAV 2000R Operation Manual

3.5.4.2 ENTERING NUMERIC FIELD VALUES WITH THE KEYPAD
Numeric field values can be entered directly using the numeric keypad. To modify a numeric field with
the numeric keypad the field is first selected using the cursor keys. The entry begins with a depression of
the numeric keypad digit. The previous numeric field value will blank and the new numeric digit, the one
which caused the edit entry, will be placed right justified. Each successive numeric key pressed will shift
left and append the new key to the right-most character position. This append shifting will be allowed to
continue for the full field width. If the user tries to enter more digits than will fit within the field, the leftmost
character will be truncated.
Pressing the ENT (enter) key terminates the number entry. The CLR (clear) key erases the field allowing
a number to be reentered. The arrow and edit keys will be ignored during numeric keypad entry. If the
user presses the ENT key when the field is cleared of all numeric data, the field is restored to the value
prior to edit mode entry. After the enter key is pressed, the system terminates edit mode.
After entering a numeric value, if the value of the numeric data moves outside its standard setting, two
asterisks ('*') are displayed, one on each side of the field.
If the data entered into the numeric field is less than the minimum acceptable lower limit, the field will be
set to its lower limit and the message "VALUE LIMITED TO MINIMUM" will appear briefly on the status
line. If the data entered into the numeric field is greater than the maximum acceptable upper limit, the
field will be set to its upper limit and the message "VALUE LIMITED TO MAXIMUM" will appear briefly on
the status line.

3.5.4.3 TOGGLE FIELD EDITING

With toggle field editing, the field data toggles between items in a list. The list will be two or more items.
To change a toggle field, the desired field is first highlighted using the cursor keypad. Then, the field
contents are changed when the SEL (select) key is pressed. Items can be toggled by pressing the select
key successively. The list toggles circularly so when the end of the list is reached, the first item will again
be displayed.
The numeric keys of the numeric keypad have no function during toggle editing.

3.5.4.4 USING HOT KEYS

"HOT KEYS" provide a quick method to modify bearing or DDM to a standard setting. The keys are only
recognized during VOR, LOC and G/S modes.
During the VOR mode, the hot keys allow the user to step through standard bearing check points without
having to edit the bearing field. Anytime the VOR mode is selected, the user may press any degree key
to automatically set the bearing field contents. Twelve different bearing settings are provided, these are:
0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, and 330 degrees.
If LOC or G/S is the current mode, pressing one of the hot keys will automatically set the DDM to a preset
value. The standard DDM keys for G/S are .000, .045, .091, .175, and .400. The standard DDM keys for
LOC are .000, .046, .093, .155, and .200. If a DDM hot key is pressed which is not a standard DDM for
the current mode the DDM value will be accepted but the message "NON-STANDARD DDM VALUE" will
appear.
Pressing the 90 Hz or 150 Hz hot keys will toggle the indicated tone off or on.
