Local Operator Interface (LOI)
Usage notes:

It is possible to move backwards in the number by scrolling to the left and pressing enter. The
left arrow appears as such in the LOI:
;

The negative symbol is only allowed in the left most position.

The Over score character “ ¯ “ is used in the LOI to enter a blank space for Tag entry.
D.2 Text entry
Text can be entered with the LOI. Depending on the edited item, up to eight locations on the top
line can be used for text entry. Text entry follows the same rules as the number entry rules in
“Number entry” on page 121 , except the following characters are available in all locations: A-Z,
0-9, -, /, space.
D.2.1 Scrolling
When it is desired to move more quickly through the list of menu choices or alpha numeric
characters without individual button presses, a faster scrolling technique is available. Scrolling
functionality allows the user to walk through any menu in forward or reverse order, enter text or
digits easily and quickly.
Menu scrolling
Hold down the left button after it brings you to the next menu item. Each of the proceeding
menus will be shown one after another while the button is pressed down. For an example, see
Figure D-1 below.
Text or digit entry scrolling
Quickly navigate through number and text menu lists by holding down the left button the same
as in Menu.
