Is that the one where u enter long & lat,(usuals) for your area
I use vbox positioner with mine
Go to Menu,set up,service searching, tuner configurataion
Should show your two tuners , ie both sat or sat & cable for example
If tuner A is for sat press ok & set configuartion to 'advanced'
Set LNB to LNB 1 -then scroll down page & enter your settings accordingly - enter settings for each sat you wish to use & press ok to save & exit
Dont forget to select diseqc to 1.2 to access long & lat settings
Good luck
