if you have a patched receiver, after channels scanning press the 0 button and the key editor will be on the screen.
If you do not have the patch go to croteam upload centar and download the file from "other receivers" folder.
Please note that patch for this receiver has some bugs. So 20 minuts after watching the scrambling channels the picture on the tv will be black.
Than you have to press the stan-by button and power up digimax again.
The patch is for first generation of scr.system. You can watch only viacces1 system on astra/hotbird (csn, mtv, srg,slo and part of tps/ab sat). If you have a chance to sell this receiver, do it!
Good Luck!
