One hearing aid is restarting when is close to another one (with others is working fine)

Hello guys,

The client has 3 Signia Insio 3px 124/56 CIC hearing aids (2 left and one right). The right device constantly restarts when it is close to one, while it works completely normally with the other. I checked that the devices are updated and that they have the same wireless code. The problem arose after changing the microphone on both devices. Have you had this problem and do you know how to solve it?

Wow that’s sounds really strange, can you factory reset, as in reset to new, start a new fitting with a new client, see what happens?
