Hello, Just purchased a EMF390 model. I have a question for the small mini jack hole above the USB port, what is this used for? Is it for head Phones or something else?

Thanks

Can I ask for your hardware version? Please open the battery door and you can see the hardware model + version on the PCB.
Thanks.

Ok, When I get in front of my unit I'll supply that information.

Based on (what hardware version is) what does this lead to? Different functions for this mini jack port?

This jack's info isn't included in the manual. It's just there for extra features.
It used to be for AM antenna but the latest hardware has it changed for earphones.

You are missing one number from 2018103, or is it 20181103? can you please recheck? thanks!

Edit. Your device's jack is for AM spectrum analyzer antenna.
