If you check Oticon’s info sheet, the only aids compatible w/ the new SmartCharger are the More’s at Firmware 1.1.1
Per @Luga’s post in this thread
The Release Text for FW 1.1.1 says:
New “MyMusic” Program
Support for SmartCharger for Oticon More miniRITE R
Support for CROS and CROS PX
General Updates and improvements
Sounds like the new charger needs the firmware upgrade.
