Phonak Roger On In not working: help!

Hi,

Today I tried to turn on my Phonak Roger On In V1 after I while I hadn’t used it, and didn’t work.

So, I thought that the battery was dead and, when I started charging it, it showed a big barred battery icon blinking a few times before it disappeared.

So, the Roger On is NOT working and I guess it’s not getting charged either.
BUT when I connected it to my PC and to the Roger Upgrader software, it got detected and I was even able to update its firmware, which unfortunately didn’t fix the problem.

The other interesting thing is that the barred battery icon keeps blinking only as long as it’s connected to my PC and Roger Upgrader is open on my PC, otherwise, if I shut down the Roger Upgrade program, the battery stops blinking.

By they way, as soon as I connected the Roger to the electricity, my hearing aids make a sound as if they got paired to the Roger On, but in a matter of fact they don’t.

What could it be in your experience? And how to fix it?
BTW the Roger ON is out of warranty and the switch seems to work because the Roger Upgrader finds it only when it’s switched on…

So, the USB cable works, the internal chipset works because I was even able to update the firmware… But they display shows only the blinking battery and the whole thing doesn’t connect to my hearing aids…

I‘d be very grateful is someone could help me!
Thanks in advance!

Yeah, I’ve tried everything now.

Do you know how much it costs to replace the battery?

Thanks!

I think this is the right battery
