ATS25 AMP upgraded to 4.2 - hi-z/50 ohms broken and FM reception degraded

[AlainFR]

Hello to all,
I just upgraded my ATS25 AMP to firmware v4.2. It went smoothly, no license issue but now my receiver is stuck on Hi-Z antenna mode, the Hi-Z/50 ohms mode switches are greyed out in the setup menus.
Also, I think that FM reception is much degraded compared to 4.17 Air Beta. Maybe because of that antenna mode switch issue?
How can I fix this please? If I can't I will have no choice but return to the previous version is this is possible.
Many thanks in advance for your help.

select the correct model of your receiver in SETUP

Thanks for you reply.

Silly me, I had done this already but I did not realize that there were more than the two choices appearing on screen :
- a very long line of ATS25 models, it looked too long to fit on the screen. I did not see the AMP model listed in it but I assumed that it was there among the others
- generic
I had selected the first choice.
Now I have seen that there are more choices by scrolling down with the encoder wheel.

Fixed. Spassiba.
