It doesn't work, as I complained in another thread. You have to relocate one of the functions to another key. I'm holding out for the next iteration when hopefully someone over there finally realizes the need for a separate menu key (and info). You'll notice that the MX1000 doesn't have a menu key either. Still can't see how the people designing these things can overlook something as basic as that, for 3 designs of remotes in a row. (SLx0000, MX1000, MX500)
