Maybe that's what I need to do with some other stuff around here too. My FE got out of sync once a long time ago with my MD-12. I have snagged that link to the manual. I can't believe I didn't go there and look at it.
From the same era, my FA and MD-15 also lost sync just once......well maybe twice, it's been awhile. I am paranoid now about being anal with my FA and FE and motor drives. Same way, everyday, no variation in anything I do.....which by the way is exactly how the manual says you should operate the thing......I know, read the manual.
Good information and reminder though!!
