Check that the forehead sensor band is placed across the middle of your forehead and that there is no hair underneath it.
Expert tip 1:
Place a dab of water on the middle of your forehead where the forehead sensor would be and wait for about 10-20 seconds for the connection to be established.
If it is placed correctly, you can see a green light and hear no beeps.
Expert tip 2:
Winter, hotel rooms and air travel can make your skin extra dry. Use the above tip to counter balance the dry skin for a better connection, so that your SmartSleep works every time!
