9 Select the Roll Off factor of the incoming signal (.20, .25, .35). Set the value to .20 
or .35 when DVB-S modulation is used, and either of the three when DVB-S2 is 
used. Use a small number to reject or filter carriers close to the same frequency. 
10 Set the input signal spectrum inversion setting (IQ), which allows the operator to 
track and select inverted and non-inverted digital signals. This is normally used 
to automatically...

17 Set the Orbital Position (Orbital Posn) for RF1, RF2, RF3, and/or RF4, in degrees. 
This is the location in orbit of the satellite currently being used. The satellite 
position (in degrees) in combination with the direction (either E (East) or W 
(West)) denotes the satellite position the dish connected to the current RF Input 
should point. This is used when the satellite is not available in the look-up menu 
list.

The following displays the Transport Default C/N Margin Relationship: 
 
5 The Audio Mute for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin 
(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, below the 
audio outputs that will be muted. The receiver uses these thresholds to 
determine when to mute the audio in the event of a noisy, poor, or loss of signal 
condition. The adjustable operating range is -30.0 to 30.0 dB. This...
