Hi, A few days ago I bought a HTM MX-500 remote control after reading a lot of people recommending it on this forum. After using it for a day, I have a question about a 'quirk' I observed on MX-500. I was wondering if it's something I need to look into. I finished programming it last night and left it on my sofa. Today when I picked it up, the light on the remote was on. Anyone know why the MX-500 light would turn on by itself? I didn't see the buttons touching any part of my sofa. Is the MX-500 defective and something I need to look into? Thanks in advance for any help.
