The front panel LCD screen displays a series of menus that can be used to
configure and control the system. The name of the current menu is always in the
upper left corner of the screen for easy identification.
• Beneath every menu name are symbols representing key presses that are
possible from the current cursor position in the menu. Note that the available
keypad moves may change during the navigation between menu fields.

• The top row to the right of the menu name displays the name of each field
available within that menu. These are called field labels and its setting is
displayed directly below.
• Beneath each label is the current setting for each field.
• Some fields may be changed by the user and others are for display purposes
only. Fields that can be changed have an arrow indicator just to the left of the
field label. During left/right navigation, the cursor skips over the labels that
cannot be changed.
The LCD is momentarily backlit with circuitry that turns off the backlighting
approximately four minutes after the last button press or warning screen. To
view the screen after backlighting has turned off, press any button once to turn
on the backlighting.
In addition to the menus on the LCD screen, the LED indicators show the receiver's
current status. The Signal light is lit when the receiver recognizes a valid carrier
signal. The authorized LED is lit when the DigiCipher II system LED is lit and either
(1) the programmer has transmitted the access messages to allow the receiver to
decrypt the signal, or (2) the signal is unencrypted or fixed key. The Bypass LED is
on when the Aux Video and Audio inputs are routed to the receiver outputs.
If the IRD is in an alarm condition, the Alarm LED is lit.
