I have two apex systems. The other night one of the systems was locked up. I noticed the lights had not turned off before going to bed. I figured I would reset it through the display but it was locked up. Not responding to anything. I eventually got fed up and unplugged it. It powered back up but lost all my outlets. It was like starting all over. I unplugged it and put everything on a dj bar. I haven't even felt like looking into it because I'm so annoyed. I love it most of the time...
