I have Phonak Naida V90SP .
A battery door of one aid is broken inside, and cannot hold a battery properly.
I would like to replace the battery door. I have a Phonak Removal Tool, and how to replace the battery door.
However, I don’t know where and how I can buy one. I would appreciate if anybody tells me where I can get one.
The color of the aid is Silver Gray.
Thank you very much.
