Magic remote/LG TV

A question about : Magic remote/LG TV

anyone had problems and solved ? (re the voice activation setup).
I get a box say this sentence (So I say just that), the sound level indicator 'reacts', then nothing. I would have thought it wanted you to say a series of Q. Tried dozens of times !!!! Help please

Best answers:

• sorry. Q= questions.
  It says "say this sentence" (there is no sentence displayed, other than "say this sentence"
  Is it like training a voice operated system in a warehouse ? Should I just talk away so that it recognises my voice? Surely there are key words it wants, like on/off/up/down,, etc ?
  If there was something displayed that it wanted me to say, I would say it, butthere isn't.
  Confused
