How to Use the Tuning Screen
On the Programs screen, tap the Tuning button. The Tuning control works like a stereo equalizer. It features four different preset options for common EQ settings, and it also allows individual control of the Bass, Mid, and Treble acoustics of the hearing aid.
You can set the tuning separately for your left and right hearing aids if you choose. You can save your changes for that program with the Save button.
