Yes, my HAs were locked, but I don’t feel like I should be sharing said code here. Even though, I don’t think it’s the same for every HAs from Amplifon.
The prompt for the code is quite obvious and I can confirm that this is not showing in the video that @user440 just recorded.
That doesn’t rule out the HAs being locked. But he’s just on the previous step: trying to connect to the HAs. He doesn’t need the PIN yet, provided their HAs are locked.
ETA: Also have you tried entering the code into the (Activate PIN Code When Programming). Perhaps it is there to lessen the burden on your Audi having to enter the code over-and-over for each of his customers.
This functionality allows the audi to instantly lock a previously unlocked hearing aid with a PIN code upon programming. This is for locking, and not for unlocking.
It seems to me like a Noahlink issue of some sort.
