When the app starts up and begins connecting to the sensor the heart rate in the circle will initially display “0” (zero) - this normal and should not cause any concern. But if the “0” remains on the screen for more than 45 seconds there is potentially an error.

Initiate a reconnection procedure In the Settings section:

• Click “Remove” sensor
• This will initiate a “Nearby Device” scan
• If sensor is found, check for heart rate showing on home page
• If sensor is not found or no heart rate display,
  • Turn bluetooth off and then on
  • If not fixed, repeat above procedure
• If still not working: close and restart app, repeat above procedure
