If you receive an exclamation point on your night card, it means that your band's signal quality wasn't sufficient during the previous night. In the type of situation, it can lead to irrelevant metrics. To prevent this from happening again, please follow these steps: 

  • Make sure you wear properly your headband.
  • If your headband is to lose, you can adjust the band size, here is how to do it.  
  • Use the headband with clean hair and a fresh clean face, please note that if you need to apply a cream for medical reasons, avoid the areas that will be in direct contact with the headband (temples, forehead) as much as possible. We also recommend that you avoid oils in your hair around the back sensors.
  • Clean the sensors of your Band every 10 nights with a disinfectant wipe (70% isopropyl alcohol- used to disinfect skin or clean medical equipment).

Once you have checked all the tips above, you can now verify good positioning with LIVE EEG. Here is how to perform this action Check good positioning with LIVE EEG.
