3.3 DTV 720 Controls and Indicators
There are three major parts of your DTV 720’s front-panel controls and indicators: the liq-
uid-crystal display (LCD), the six push buttons, and the eight LED indicators. Essentially
all control available through the terminal is also available via the front panel (shown below
in Figure3.20).

Push Buttons
These six push buttons (shown below in Figure3.21) are your means of commanding the
DTV 720 from the front panel. The four arrow buttons allow navigation through the menu
screens and character selection when editing user-input fields. The Enter (ENT) button is
used to select menu options (downward navigation), to open user-input fields, or to com-
mit user input to the DTV 720. The Escape (ESC) button allows exit from user-input fields
without saving the entry or selection. ESC also provides upward navigation through the
menu structure to the Home screen. The arrow buttons also provide navigation through
user-input screens and switching between user-selectable options.
