Little remote is what came with the UMC-1 at first, then cam the aluminum remote. Or what I call the Home defense remote. Anyway one of the old updates canceled the plastic remote ,and so now it dose not work with the UMC-1. Plastic remote if I remember was turning other gear on and off ,up and down are something like that, I don't know mine was fine.
Sometime I think I have a deferent UMC-1 then everyone else, just not having the problems I read about. Could be because I do my updates with a strip down laptop. Are maybe not.
