You have to install the fitting software on a Windows Computer and then (use a hearing aid programming device/hardware) to connect the hearing aids to the fitting software. Also, different hearing aid models may require different hardware for connecting.
As if that wasn't complicated enough, ReBranded hearing aids (which is what you have) are even more complicated and sometimes also locked.
Suggestions:
- Say what model hearing aid you have.
- Read a DIY School Hearing Aids (v2.2) PDF File named (Unlocking ReBranded Hearing Aids)
