Retevis RT 647 PMR 446

[rjj1956]

Hi guys
Anyone help me out with a screenshot of the factory settings on chirp from a Retevis 647 PMR 446.
We have 3 of these in our club and I am trying to add another radio to the three, it`s a different breed so need to programme it identically.
I can`t get the Retevis, using programming cable to be recognised by usb, tried everything.
The 3 radios are running straight out of the box, bought from Amazon a couple of years ago, and not been altered, so should be on factory settings.

Can anyone help please.
