>From my experience, and I have about 8 9390s, some play and some do not. It was explained to me that they have older firmware in them and will not work unless they had the new week rollover number programmed into them. Most, as I said, have old firmware, before the new rollover was introduced. I believe right now only two of mine work. I used to have three working, but, one of them quit a few years ago, for no apparent reason. With too many projects, I have not had much time to look into it. Also, programming them from the front panel is a real pain. Regards - Mike
