As someone of you knows these HAs play 2 beeps as warning for low battery status (supplying: 312 single-use batteries). I just wonder if it’s possible to modify this kind of warning turning it into a voice that says “battery must be changed” or something similar, anyway a voice and not only a couple of beeps. Just as an example, Widex Passion HAs play a voice for that.
I’ve posted here because afaik that’s not possible via app/smartphone by a “common” user so I’d want to know if there’s a possibility via prof tools and, especially, how to do that.
