E (EDIT)
This function key activates or deactivates the softkeys and edit fields
within any screen where editing is appropriate. You will quickly learn
that this is an important operating feature in the unit. Press the
E
key
when you want to start editing a screen and again when you have
finished editing. If after editing you press a function key and nothing
seems to happen, check to make sure you didn’t accidentally alter
your information and press the
E
key to end editing. Most edit screens
provides an
Escape
softkey. If you decide for some reason that you
don’t want to use the changes you have made, pressing the
Escape
softkey will restore the original information. However, once you press
the
E
key, all changes are accepted and the original data is lost.
C
C (CLEAR)
This function key is probably the least used of all the function keys;
however, it can save you some otherwise frustrating editing time. This
key allows you to erase or clear one character at a time. If you hold it
down, it will erase the entire line that the cursor is currently on.
CURSOR
This function key is the most used of all the function keys. As its name
suggests, this key is used to move between edit fields. It also allows
you to move between function screen pages (by pressing left or right).
In addition, many of the edit fields allow you to use either the cursor
key or the
Change
softkey to scroll through or select from predeter-
mined choices.
