The human interface is organized into display pages. Each display page provides the operator the ability
to view specific information, or perform some specific task(s). The operator navigates from page to
page by pressing keys, turning knobs, etc. Navigation can be achieved either through the touchscreen
or through keys/knobs/push-button actions. Display pages are organized in a tree structure, rooted at
the normal operation page. All features are three (3) actions or less from the normal operation page.
Figure 2 shows the tree structure of the display pages identified in this document.
