There are two basic screen types used to build the interface application, Text Screens and Menu
Screens.
4.4.1 Text Screens
Text screens are used to display information to the user, but do not allow for any user input.
4.4.1.1 Display
When the screen is displayed on the LCD panel the first four lines are visible, and if there are
more than four lines in the screen, a plus (+) sign is displayed in the lower right hand corner of
the display.
4.4.1.2 Buttons
The Enter, Left, and Right buttons do nothing on a text screen.
If the screen contains more than four lines the Up and Down buttons scroll up and down one line
at a time.
The Escape button navigates to the previously viewed screen.

4.4.2 Menu Screen
Menu screens are used to navigate around the system and for data entry. Each menu is
composed of menu elements that serve different purposes. There are currently four menu
element types, Text, Command, Selection, and Edit.
4.4.2.1 Display
Each line is one menu element as described above. Normally the first line is a Text element,
which is the title of the menu. When the menu is scrolled, the title remains fixed while the bottom
three lines scroll. The plus (+) sign is displayed in the bottom right corner to indicate that there
are more lines below just as in the Text Screen.
A menu screen has a cursor that is displayed as an asterisk (*) in the left most character position
and indicates the active element. When the screen is entered the cursor is on the second line
(first line below the title).
