Success !
Connexx/SiFit works fine .No code seems to be needed .These NHS hearing aids are not locked.
Thank you very much"
I found this from a different thread, seems the stretta is not locked, and connexx software should find it.
I am getting the batteries size 13 in a few days, than I will try the actual aids to connect wireless with the connexx programming software through NOAHLINK Wireless…
will update here with results.
