LCD screen
relationships Figure 3.3 below shows LCD screen relationships from the top level down-
ward. These screens are structured in two dimensions, reflecting their relation-
ships as peers, as parents, and as children of other screens. The up-and-down
dimension represents the parent-child screen relationships (navigated with the
ESC
and
ENT
buttons). The side-to-side dimension is the peer relationship
(navigated with the right- and left-arrow buttons). A parent screen is usually a
menu screen covering some category of U4650 operation or status. Its child
screens are opened by pressing
ENT
at the parent screen. These child screens
then provide access to finer details of unit monitoring and control. Multiple
child screens of a parent menu screen are all peers to each other. However, the
most significant set of peer screens are the top-level screens that have no par-
ent and that include the home screen. The home screen may be reached by press-
ing and holding
ESC
(or pressing it repeatedly) from any other LCD screen.
Appendix A Monitoring and Control Details gives more details on screen
types and using front-panel push buttons to navigate and control the U4650.
