- Ensure your NuraTrue and case are charged. You can find our Charging Your NuraTrue and Case article here.
- Ensure the infrared (IR) sensor is clean and not obstructed. The IR sensor is located near the base of the ear tips, and there is a circular cutaway for the sensor on the wings. Try wiping the IR sensor with a tissue or cloth, and make sure the wing fixture isn't covering the sensor.
- Reset your NuraTrue by performing a Device and Sleep Reset. If the issue persists, please try a Factory Reset, if possible. See our NuraTrue Reset article here.
