What it may mean: The phone was unable to pair the Lingo Biosensor.
What to do: Try pairing the Lingo Biosensor again. The NFC antenna is on the top edge of the phone. Pair your Lingo Biosensor by holding the TOP of your phone very close to the biosensor. Move your phone around slowly if needed. Proximity, orientation, and other factors can affect NFC performance. For example, a bulky or metallic case can interfere with the NFC signal.
