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 dis-
play elements. It also shows the placement of the menu keys in rela-
tion to the display. The paragraphs that follow provide descriptions of
the menu display elements and the menu keys.
