Touch Buttons Your nuraphone has two touch buttons positioned on the adjuster covers on right and left. You can configure them to perform helpful functions without having to use your mobile device. To change these at any time go to nura App ➝ menu ➝ nuraphone settings ➝ customise buttons. Note: As many of the functions require a Bluetooth connection to work correctly, the touch buttons are only functional in Bluetooth mode. They do not work when a cable is plugged in.
