Andrew,
The support group for the NanoVNA-F that you own is located at
/g/nanovna-f . You should leave a message on the board there (
/g/nanovna-f/messages ) and hopefully the developer of the NanoVNA-F will respond. The only documentation I was able to find was the same quick start guide you referred to at
/g/nanovna-f/wiki/home . Hopefully over time the members of the nanovna-f group will start to produce better documentation for the NanoVNA-F. We went through similar lack of documentation when the NanoVNA was first marketed.
