Tuner setup/satellite setup Vu+ Duo2 (Nordics)

Hi

My new image of OpenPli crashed after update yesterday, so I flashed a new one again. My settings are gone so I could need some help.

I only have one tuner with 4,8E and 0,8W as active satellite positions.

But how do I setup my tuner for this? Do i disable tuner A or B?? Which satellite position should be A and B with the active tuner and etc.

Could someone give me a brief how-to and maybe some screenshots?

Thanks :-)
