3.4 CHANGING PARAMETER SETTINGS - MODIFY
There are three types of parameters in the instrument: values (numbers), text strings (groups of characters), and
choices (selections made by picking one of a group of displayed descriptions).
With a modifiable parameter description and its setting displayed, pressing the MOD key places the unit in
Modify where the setting can be modified.
3.4.1 CHANGING VALUES
If the setting is a value (number), the cursor will be positioned on the right-most digit. The LEFT ARROW and
SCROLL keys will move the cursor left or right. The UP and DOWN keys will increment or decrement the value
with rollover and rollunder through all digits to the left of the cursor. Pressing the ESC key exits Modify, no
change being made to the original value. Pressing the ENTER key exits Modify and the new value will be
displayed and entered into memory.
3.4.2 CHANGING TEXT
There are two ways to change or modify text. The first, Character Modify, is accessed by the initial pressing of
the MOD key, and the second, Character Selection, is accessed by pressing the MOD key while being in the
Character Modify mode. Each has its benefits, and you may prefer to use one or both methods, depending on
the modification to be made. Pressing the RESET key after pressing the MOD key will clear all characters from
the curser to the right.
• If the setting is text ( e.g. units, tag, etc.), the text will be left justified and the cursor will be positioned on the
left-most character. The LEFT ARROW and SCROLL keys will move the cursor left or right.
• In Character Modify, the UP and DOWN ARROW keys change the character by scrolling through a list or string
of available characters. The LEFT ARROW and SCROLL keys will move the cursor left and right to allow chang-
ing another character. Pressing the MOD key enters Character Selection. Pressing the ESC key exits Modify, no
change being made to the string. Pressing the ENTER key exits Modify and the new string will be displayed and
entered into memory.
• In Character Selection, depressing the MOD key twice will initiate Character Selection. The character to be
changed (on the lower line) will be replaced by the "block" character (all dots lit), and the upper display line will
show a character selection line, instead of the parameter description. The character selection line which contains
the current character will be displayed with the cursor positioned on the current character. The LEFT ARROW
and SCROLL keys will move the cursor left and right on the current character selection line. The UP and DOWN
ARROW keys will change the line of characters displayed for selection. Once the cursor is positioned on the
desired character, pressing the MOD key will store the desired character in the lower line, the "block" character
will move to the next position on the second line, and the character selection line which contains the next charac-
ter will be displayed with the cursor positioned on that character.
• While in Character Selection, pressing the ESC key exits Character Selection and returns the unit to Character
Modify where selection of another character may be made or pressing the ESC key again exits Modify.
• While in Character Selection, pressing the ENTER key after modifying a character will exit Character Selection
and the new string will be displayed and entered into memory.
3.4.3 CHANGING CHOICES
• If the setting is a YES/NO choice, the YES/NO choice line will be displayed and the current choice will blink.
The LEFT ARROW and SCROLL keys will switch the selection between YES and NO. Selecting the choice and
pressing ENTER will exit Modify and the new setting will be displayed and entered into memory. Some YES/NO
parameter choices are initialized to NO. When changed to YES, the unit may automatically advance to the next
parameter upon depression of the ENTER key.
