Looks like a nice machine. That rotary looks nice and hefty! Thanks for the review. My fiber is the F1 Ultra.

Your black knob is for a fuse compartment, - just in case you have surge of electricity.

Without reading anybody else’s comment. That one connector that you don’t know what it is. Looks like a grounding port to me. Some devices come with separate grounding connectors. That’s my best guess. I mean from the view that I can see lol. For all, I know it could be just for an antenna to get HD channels.
