In order to get optimal performance from your Mendi you should make sure of the following:
1. You are in a calm environment as well as mindset. Unless you'd like to test your focusing ability when there are distractions.
2. The headset sits firmly on our forehead, neither too tight nor too loose.
3. There's no direct source of light shining on to your Mendi (forehead). Direct light may interfere with the sensor reading - dim environment is ideal.
4. Once your Mendi is on and the sync is complete the app will guide you through the rest.
