Solution 1. When wearing the device check to see if you get the “happy tone” indicating that the device is seated correctly for use.
Instructions for correct placement:
- the front sensor is in the middle of your forehead;
- the strap is tightened correctly
- the sensor behind your ear is seated correctly and you will get the happy tone.
Solution 2. Check if your SmartSleep is displaying your Sleep Boost number or number of tones in your app the next morning.
