I assume there will be a way to download and save my existing programs from my aids in the software before I start tinkering.
The way that we usually advise is that you “set up a patient” which you call something like “your name original” then you connect up the aids, save the session and disconnect. Then you set up a second patient that you might call “your name 2024” or whatever, then connect your aids, save the session, but now you can get tinkering. This gives you two ways to get back to your original settings. (The first patient and the first session on the second patient.)
If you really want belt and braces, you can now “Export patients” to a location on your PC and then copy it to a USB stick which you put safely away somewhere else.
