Thanx Conker,
I tried all of what you state in your post long time before, since I am ABLE to read and understand even complex technical issues in manuals.
All of that operations do not work with my US Thales replica. Even with your premade programming files.
So I dont know why it does not work, even if I do all the operations right.
Maybe you could give me a prog file that you have confirmed to work with the F-Keys, I then do a Full Reset and write that file onto the radio.
If it still does not work with the F-Keys, it might have hardware prob?
