So just trying to work out which Signia models they are, are they the size 10 battery, obviously they don’t connect to any app right ( no LE bluetooth?) as this would explain the Noahlink not connecting, so could be connexxAir or HiPro.
I’ll keep looking to see if I can find what they are.
Ok so I’m thinking they will be the insio CIC which is no Bluetooth and programming connexxAir or HiPro, as to if they are locked or not I don’t know, some people have had success with the Phonak/Unitron rebranded models. Signia should be the same.
