Occasionally, after having receiving confirmation that the headband is working, your mobile device may lose connectivity with the headband and appear as though no sleep data is being captured (flashing white line). This is normally due to a disruption of the Bluetooth connection between the Zeo headband and the mobile app, either because the app crashed, was closed, or the Bluetooth signal gave out.
However, since the headband itself can record and store a full night of data in its internal memory, you can salvage this lost night by following these simple steps.
While on the home screen, press and release the headband button-you don't need to hold the button or wait for the light to blink-and the captured sleep data should be sent to the screen. You can then dock the headband and resume your normal interaction with the application.
From the Home screen of the Zeo app, press the Import button on the top right corner and follow the instructions on the screen.
