DATA DISPLAY AREA
The data display area consists of the data display and the surrounding
menu keys. The data display is a dot matrix liquid crystal display
(LCD) that provides 16 lines of 40 characters each. Information is pre-
sented on the LCD in the form of menu displays. The menu keys
either select the main menu to be displayed, select a sub-menu of the
current menu display, or control a function on the current menu dis-
play.
Figure 3-2 shows the format of the menu display and identifies the
display elements. It also shows the placement of the menu keys in

tions of the menu display elements and the menu keys.
