Menu Screens
A hierarchical menu structure is used to access the various screens. Each menu screen can have one to four
lines of information. Optionally, the last menu selection can access one of a set of screens that can be
navigated with the UP/DOWN arrow keys (see the scrolled menu structure below). Menu selection is
initiated by pressing the MENU key, which changes the display from a data screen to a menu screen. Menu
selections are then made using the arrow keys according to labels on the right side of the display (the arrows
are ignored). When the last menu item is selected, the display changes to the selected data screen. An
example follows showing the selection of the “VIEW COMPRESSOR (n) screen. Suppose the initial screen
