DATA STORE AND RECALL WITH THE CLR AND ENT KEYS.
The CLR and ENT keys are used for data entry. The ENT key caus-
es the changes made to the field under the cursor to be stored. The
CLR key can be used to restore the original value of the field until the
ENT key is pressed. The changes to a field are also stored when the
operator moves the cursor to another field.
CLR KEY
1. After data has been entered but before the ENT key is pressed
or the cursor is movedfrom the field:
A. If the cursor is in the character cursor mode and the field
contains ASCII strings, such as an ALE address or AMD
message:
The first press of the CLR key clears the data field from
the point of the character cursor to the end of the field.
The second press of the CLR key restores the original
data.
The third press of the CLR key exits the character cursor
mode.
B. For the field cursor the first press of the CLR key restores the
original data.
2. The CLR key is also used to exit from a page and remove the
cursor. After satisfying the CLR key actions above, the CLR key
returns you to the idle page. The next press of the CLR key removes
the cursor, if allowed.
ENT Key
As the operator progresses through the menus the ENT key or the
CRSR knob can be used to move the cursor to the next field or item.
The ENT key provides a benefit of leading the operator through a list
of associated parameters. After the operator changes a field, press-
ing the ENT key indicates acceptance of the change. The cursor
moves to the next field or a parameter is displayed on the bottom line
to show a response to this action. For example, on the
Operation/Interval page pressing the ENT key stores the change to
the current interval and displays the next interval parameter, if there
is one. Using the ENT key instead of the CRSR knob prevents the
operator from accidentally skipping a field, since the CRSR knob
moves the cursor rapidly. Using the operation/interval page as an
