15  In the Crossover field, enter the crossover frequency for RF1, RF2, RF3, and/or 
RF4. This is an internal threshold frequency used for selecting the LO1 or LO2 
frequency, depending on the current downlink frequency settings. This option is 
only used in dual-band LNB applications. 
You can enter a value in a range from 0.0 to 15.0 GHz. In single-band LNB 
applications, set this value to 0.0. 
16  Choose the signal polarisation setting (Horizontal, Vertical, or Automatic) from 
the Polarisation drop-down list. This setting is only applicable when the LNB 
Power is set to H-NIT or V-NIT. It marks the polarity of the signal connected to 
the current RF input. 
17  Enter 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. 
For manual configuration, enter the location of the satellite using the numerical 
keypad. The receiver will not recognize the satellite name and identify it as 
Unknown. This setting is required to resolve any ambiguity between RF inputs 
during automatic disaster recovery. 
18  Choose the east/west flag for RF1, RF2, RF3, or RF4 from the East/West Flag 
drop-down list. This is the satellite position the dish connected to the current RF 
Input should point. The options are East, West, or N/A (Not Applicable). 
19  Click Apply
 
Validating the Orbital Position 
Click Validate Orbital Position to validate the RF inputs to match those expected by 
the network. The receiver will check to see if all frequencies in the Network 
Information Table (NIT) can be tuned to. The Date is displayed as the last date that 
the Validate operation was performed. 
 
Reacquiring the Network Information 
Click Reacquire to re-acquire the signal using the tuning parameters from user 
settings. The Reacquire Network Information window is displayed.
