Hi @Mike61 Welcome;
Here's a clip from the DIY School Hearing Aids (v2.2) PDF File named (02 How to Program your Hearing Aids);
Self Programming Don’ts:
When installing hearing aid fitting software don’t choose the option to participate in the improve software feature. No need to have extra automatic communication with manufacturer!!
Don’t use the Noah system software (currently Noah4 or Noah-ES). Noah system software is never required for any manufacturer’s fitting software. Professional Audiologists need the Noah system software to group many clients into a one Noah database and provide automatic startup interfaces for the different manufacturer’s fitting software. If you are a self-programmer, it is simpler and cheaper to run the manufacturer’s fitting software standalone. When fitting software is run standalone it will use its own database. Repeat,,, Do not use the Noah System software!
Don’t confuse the above Noah system software (currently Noah4 or Noah-ES) with the Noahlink Wireless programming device. Don’t confuse an old obsolete programming device named NOAHlink with the Noahlink Wireless programming device. Noah, NOAHlink, and Noahlink Wireless are three different things.
