Use The NORDICTRACK Sleep Coach Important Sensor Tips The use of the sensor close to a source of vibration may have a negative effect on the accuracy of measurements. The sensor does not have a battery and must be left plugged in to operate. If it is not plugged in, or if a power failure occurs, no sleep data will be collected. Once the sensor has been paired with the iFit Sleep app on your iOS or Android device, the sensor will automatically sync with your device any time the app is active on your device and your device is within about 30 feet (9 m) of the sensor. The sensor will be activated automatically when you lie down on your bed. Important iOS or Android Device Tips To use the NORDICTRACK Sleep Coach, you must have an iOS device (iPhone 4s and later) or an Android device (Android 5.0 and later) that supports BLUETOOTH 4.0 wireless technology. Your device's battery will be used more quickly while your device is receiving data from the sensor. It is recommended that you leave your device connected to your charger while you sleep. If your device is not connected and its battery drains, no data will be received from the sensor. BLUETOOTH must be activated on your device for data from the sensor to be received. If the BLUETOOTH connection is lost, it will not be possible to retrieve any lost data. You must enable Wi-Fi® or another data connection on your device to use some features of the iFit Sleep app (see OVERVIEW OF THE IFIT SLEEP APP on page 8). Note that this will affect your device's data usage. If you disconnect your device before you sleep, reconnect it after you wake up to use all of the features of the app. 7
