HELP! I bought this remote through RadioShack.com. Unboxed it-WOW! Great look and feel. Put in batteries, and hit the light button and the unit emits this low but fairly high-pitched hum/buzz. Does anyone else have this problem? I thought it might be bad so I called RS's 800# and they told me "shouldn't be humming-take it back." So I took it to my local RS just now and test THREE other units and they all did the same thing (though I thought one was slightly quieter than the others-that's the one I took home). PLEASE tell me someone else is experiencing this and if not, how do I go about finding a "quiet" remote!? ;) Don't misunderstand me, it's far from LOUD, but it's noticeable in a quiet room. Thanks!!
