So the left one beeped every hour 3 descending tones.
I have used target to read them, there is no obvious warning, but I note that I made a change on the right one a few weeks ago - I wonder if any change resets the timer ?
I have changed the bluetooth name and saved that back to the devices, will wait an hour and see what happens. If it still does it then I will reset the aid with the trial option then restore my last session.
