The X1(s) has been designed to be used in Activities Mode, think of Devises Mode as nothing more than telling the X1(s) what equipment it is going to control when setting up, so once setup you should not need to go into Devises and the Off button then does what you want, turns everything Off. If you need to use Devises Mode to operate your equipment then you have not set it up correctly or if you actually want to manually switch control between devises the U2 is a better remote. The X1(s) “used” in Devises Mode is a horrible remote but in Activities Mode it's great.
