Press the RF Menu button and select the antenna input port
number. Set the satellite number and V/H polarity for the
desired programmer's satellite feed.

Press the RF Menu button a second time to set the RF center

Verify the front panel RF Lock is lit and signal meter has at
least two LED bars lit. The BER threshold meter should
have no more than three led bars lit. If the BER threshold
meter is completely lit and the signal meter has no bars lit,
without RF Lock, then the receiver is not locked to the
desired RF carrier.
–
With the receiver locked to a valid DC-II signal, press the
Program Menu and set the VCT and VC numbers to the
correct setting for the program you are selecting. As you
enter the VCT number, the receiver will indicate VCT Not
Defined. Complete the VCT number entry and wait until the
receiver indicates VC Not in Table. When the receiver
indicates VC Not in Table this means that the current VCT
you entered is a valid table and is listed in the VC Map the
receiver just received.
–
Enter the VC of the program your are selecting. As soon as
any correct VC number in the map is entered the display will
change to indicate the Source Name of the selected program.
The MPEG program number will also be indicated.
–
With the correct VCT and VC number entered the receiver
will proceed with decoding the video/audio and data
information. Monitor the front panel Authorize LED. If the
program is in the clear or fixed key encryption, the receiver
will automatically authorize and display the video/audio. If
the program is fully encrypted the Authorize LED will blink
until the receiver is hit with an authorization signal.
