The upper left hand corner contains the name of the screen (ie. DISPLAY GROUP:). Knowing the
name of the screen will assist you in the orientation of the menu system. On some screens to the
right of the screen name, will be the name of the selected item from the previous screen as shown
in Figure 3.

Some screens have more then one page associated with them. The current page number and
the number of pages which make up the data currently being displayed on the screen is shown in
the upper right hand corner, (ie. showing page 1 of 3 pages).

Along the bottom of the screen are one or two rows of 'Softkeys' which represent the assignment
to the actual function keys. In Figure 2, Softkeys F6-F10 are shown. Pressing F8 will display the
next page of data.

In the very lower right-hand corner is a small dot. This dot indicates the healthy state of the
terminal. Under normal conditions this dot will flash at a rate of .5 Hz. During communication
errors, the dot will flash at a rate of .1 Hz.
