Moog Etherwave Theremin

Right, so Mom bought me a Moog Etherwave Theremin for Christmas. I love it very much, except for when it's on, and I am not near the instrument, it contimues to produce a low tone. I just need to know how to stop this? I could not find any info in the manual? I did contact Moog, to see if they could tel me what too do?

Actually, I figured out, how to stop it, making that tone, when I walk away.
