Software for Adjusting hearing aids

Rob <captinlogic@...>

Today I got some new hearing aids. Phonak something or other's, I missed the model.
The technician hung some kind of wireless receiver around my neck and was able to adjust the hearing aids using that thing somehow.
My question is. Can we get the software and that piece of equipment so we can adjust them ourselves? Or are we pretty much at the mercy of the audiologists and technicians. Do you need a special license to get the software?
