Why do I have difficulties using the touch ring of my SAT(s)?

The touch ring works with capacitive technology. It reacts to the electrical properties of the user. These properties are different for each person. If you're having difficulties using the touch ring, the default sensitivity setting of the ring might not work for you. To change this sensitivity tap on 'Touch Ring Sensitivity' in the settings of (each of) your SAT(s). A pop-up appears in which you will be able to adjust the sensitivity setting to low, medium, high or maximum sensitivity. The default is medium. You can also decide to switch off the ring.
