Can you save settings in the Resound smart 3d app?

I can help.
Go to your Smart 3d App.
Select a Programme to start from eg. All Around.
Click on the Sound Enhancer box near the bottom of your app screen.
Adjust the sound levels on the next screen to those you require.
Select Add a Favourite near the bottom of the screen.
Give your new favourite a Name.
Click Save.
Job done!
Your new Favourite sound profile settings are saved and will not be erased unless you have to un-pair then re-pair your hearing aids to your phone.

Excellent. Thank you!
