About a month ago, I used my brand new G30 wireless for the first time. I move quite energetically because of the genre of music I play. Every time I jump or move abruptly my receiver would shut off. Then I would go back and forth between "On" and "Off" none of the lights came on indicating any signal. I left the receiver on after packing up to get off stage, and later that night I pulled it out and it was on. I'm assuming its a connection problem. Does anyone else have any problems similar to this? I have a 2-year warranty.
