To personalize your treatment therapy, SONU needs facial scanning capabilities which are only available on iPhone X and newer phones.

To customize treatment therapy, the SONU app needs to map an individual’s sinonasal cavities. While the camera must be enabled for the face scan to work, we do not take or store photos of your face.

A green LED light will light up when fully charged and still plugged into the charger (for SONU 1.8.22 and later versions). Earlier versions will show the green light for 1 minute, then turn off so you can check if the light is off on versions prior to SONU_1.8.22.

These are transducers (speakers) that deliver gentle acoustic vibrations. They are made of medical grade silicone.

Positioning the band on the forehead with proper fit is important for treatment efficacy. You should adjust the band to ensure that it does not slip side to side when you turn your head. To avoid discomfort at the contact points, do not overtighten. Generally you should be able to place your index finger between the band fabric and your head easily.

Volume can be increased with the volume buttons on the side of your iPhone.
