i cannot find "setup positioner" under Advanced option where is it ?What type of LNB do you have?
If you just have a single output, non FBC LNB, then just choose:
Configuration Mode Simple
Mode Positioner
Enter your Longitude, - Longitude readings = East, = Longitude readings = West.
Enter your Latitude.
Then Save.
You could also select the Advanced option, and setup positioner, with DiSEQc 1.2, then enter your Latitude, and Longitude.
