The module is delivered without instructions or description. But these are not necessary because the module virtually self-explanatory: map (in my case, Unitymedia) pure, plug in module in TV (LE46C750 by Samsung), Start Scan and experience the world in HD and Digital. Easier than ever. The reception is brilliant and the switching times compared to Unity Media Box fantastically. All in all only a recommended alternative to the receiver of Unitymedia !!!
