After reading the manual that comes with the unit it identifies the usb c port but the other port does not seem to be identified. Is the other port a headphone port? Some kind of grounding port? or something else?

Thanks.

Thank you, I was also searching for the use of that port.

A teardown video or thread of the GQ EMF-390 was one of the first things I searched for, but I didn't get any useful results until I found this forum, which at least provided some pictures of an EMF-380.
Is the EMF-390v2 build just like the EMF-380, with out the 0-10ghz detection?

Yes. And also no data saving.
