After trying this for about an hour, I gave up and figured everything was OK. Boy was I wrong. Holding down the voice 1 and voice 2 buttons did some weird things to the Harmony M, did not display the current operating system, and really produced a host of problems during today's job. I finally did a factory reset, then redid my original settings and saved them. Things are back to normal now, Whew!
