3.2.2. Front Panel Displays
The main LED display on the 1200DD series displays consists of six 7 segment digits and a two character
14 segment alphanumeric display. In normal display modes the six digits are used to display the time or
date. The alphanumeric display is used to display the AM/PM indicator when the time is being displayed
in 12 hour mode. The alphanumeric display is used to display the day of the week when the date is being
displayed.
When in the Setup menu, the alphanumeric display is used to display menu items, and the six large digits
are used as alphanumeric displays to indicate the value of the menu item. Not all of the alphabetic
characters can be displayed using the seven segment digits. Figure 3-4 shows the seven segment
displays used to represent the various characters. Note that some of the alphabetic displays are identical
to some of the numeric displays.
