First, check to make sure your headband is fully charged. The headband should charge on top of the bedside display for about two hours before it is used. If you see a pulsing battery icon on the bedside display screen, the headband is charging.
Next, check to see that your headband is communicating with your bedside display. If it is communicating, you will see a headband icon appear on the bedside display screen when you undock the headband.
When you put on your headband, you should see an icon of a head wearing the headband appear on the bedside display screen. If one or both of these do not appear, try unplugging your bedside display for 10 seconds and then plugging it back in.
Static electricity, especially in the winter, can cause the headband and bedside display to stop communicating. After you’ve power cycled your Zeo, try to touch something metal before picking up the Zeo Headband. Also make sure not to touch the silverized fabric sensors, or anything else on the sensor pad or module, with anything but your forehead.
