My product displays an inaccurate heart rate or loses communication with the optional heart rate chest strap. What should I do?

• Try the following:
  • Make sure you are wearing the heart rate chest strap snugly with the electrodes pressed against your chest as shown below.

    
    
    

  • Moisten the electrodes on the heart rate chest strap.
  • Detach the heart rate chest strap unit from the belt, clean the snap buttons on both, and reattach them.

    

  • Reset the heart rate chest strap by removing the battery, turning the battery over, and placing it in the product with the negative side facing up. Leave the battery there for three seconds, then remove it again, turn it over, and place it back in the product with the positive side facing up.
  • Replace the battery in the heart rate chest strap.
