Soft-keys
The six soft-keys to the right of the display are used to select menus or menu
functions. The functions of the soft-keys are indicated in the small boxes on the
display just to the left of the soft-keys. The functions of the soft-keys change
depending on the selected menu. The bottom soft-key is usually RETURN.
Pressing this key exits from a sub-menu or window and returns to the previous
menu. (For an outline of the menu structure, see Section 7.)
Numeric Keys
The ten digit keys, the decimal point, +/-, and EXP keys are used to type nu-
meric data or make numbered selections.
Enter
The Enter key is used to enter a new parameter value or option. When the value
of any parameter is changed Enter must be pressed to accept the new value. If
Exit, Home, U, or D, are pressed before Enter, the cursor will leave the pa-
rameter and any changes made to it will be canceled. Within a window with a
list of parameters, pressing Enter will also move the cursor down to the next
parameter. If the cursor is at the bottom of the list, pressing Enter without
changing the parameter will exit the window. The Enter button may also be
used during some operations to affirm or continue with an action or choice.
NOTE: The Enter button must always be pressed after changing a param-
eter to accept the new value or option.
Del
When entering or editing a numeric parameter the Del (delete) key is used to
delete a digit that is underscored by the cursor.
Exit
The Exit key is used to cancel an operation, exit a window, or return from a
lower menu to a higher menu. In any window, pressing Exit will immediately
exit the window and skip to the next window or return to the menu. If a param-
eter is entered or changed and Exit is pressed before Enter, the change will be
canceled. During some operations the Exit button may be used to cancel the
operation.
Home
The Home key is used to return from any sub-menu, window or entry to the
main menu. If a parameter is entered or changed and Home is pressed before
Enter, the change will be canceled. Home may also be used to refresh the
screen if it happens to become corrupted for some reason.
