How a align dish with latest enigma2 dm800?

  • Hi,
    I've tried many tools but none of them works. I want to tune my dish to a new sat. So, i don't have any channel stored within my dm800. The dish is on the roof, so I can not see the output of SatFinder pluging on the TV screen because it is too far. I've fried a lot of mobile software tools, but none of them works without having at least one channel stored for the tunner.
    What should I do?
    Cheers
