About the Front Panel
The D9854/D9854-I receiver is operated using controls and indicators on the front
panel. These include the numeric keypad, the Navigation/Selection keypad, the
LCD, the Alarm and Signal indicators. These are shown in the following illustration.
LCD
The LCD provides information on the selections available at any menu level, current
settings for parameters, and certain status and alarm indications. This is a 2x40,
backlit LCD display. The top line may be status data or identifier information. I t can
also display optional functions available for tuning operations. The bottom line will
show selections or parameter values available using the navigation/selection
keypad. The items are selected by pressing the SELECT (center key) or the (down
arrow) key on the navigation/selection keypad.
Keypad
The numeric keypad is used to enter alphanumeric values. The MENU key sets the
software to the initial menu and returns to the previous menu. The MENU key can
also be used to cancel a numeric entry at any point during the entry sequence, and
the (left arrow) key allows backspacing through the entry.

decrypt purchased programming. For setup information, see
