Soft Keys The Soft Keys are multi-functional keys that use part of the display to
identify their function at any moment. The function of the soft keys allow
immediate access to the menu structure and most often used menus and
screens. They are located directly underneath the display and as the keys'
functions change this is indicated by user-defined labels in the lower part of
the display, so that the user knows what the keys are to be used for.
To change a soft key, place the menu cursor “>” on the item of the selected
menu or screen you wish to set. Press followed by the selected soft key
within 1 second of pressing the right-arrow key. The edit soft key prompt
will be displayed for configuration for the new label.
Note Not all menu items may be assigned to soft keys. If a particular menu
or screen item cannot be assigned, the key assignment screen will not come
up upon entering right-arrow-soft key combinations. All items under the
Service menu (including the menu itself) cannot be assigned soft keys. 
