Label List Management
The label list contains 75 of the most recently used labels. The list does not save
duplicate labels, nor does it save multiple labels that differ by, at most, two
trailing numeric characters.
The label list is non-volatile. Thus, after you use the label list for a while, your
labels will predominate, making it easier to customize the instrument display for
your needs.
When you first begin using the instrument, there are some blank entries at the
end of the label list. As you define custom labels, these spaces are filled. One
blank space is always retained at the beginning of the list to allow entry of a
new label. When you initialize the label list, all of your custom labels will be
cleared, and the label list will be returned to its factory configuration.
To define a new label

To use an existing label as the basis for the new label, use the Entry
knob to choose a label from the list of labels. Then press the
Copy
softkey.
The Entry knob moves the cursor through the label list, then through the
character list. The label list includes all predefined labels, and custom labels
you have defined, unless it is re-initialized. When you press the Copy softkey,
the selected label is transferred to the entry field.
