I'm wanting to load another complete comfiguration into my SV system, by way of my Dynon USB memory stick. I don't want to overwrite my current configuration, in case I want to go back to it. I would appreciate it if someone can tell me the steps I need to take to save my current configuration and what I must then do to go back to it if I don't like the 2nd configuration. This 2nd configuration was sent to me as a completed SV setup. Thanks
