Tips for Erratic Heart Rate Data

If the heart rate data is erratic or does not appear, you can try these tips.

  • Press the button to make sure the heart rate monitor is awake.
  • Reapply water to the electrodes and contact patches (if applicable).
  • Check that both snaps are fully connected to the strap.
  • Warm up for 5 to 10 minutes.
  • Check that the strap is snug enough to ensure minimal movement during the activity.
  • Follow the care instructions (Caring for the Strap).
  • Move away from sources that can interfere with your heart rate monitor.

    Sources of interference may include strong electromagnetic fields, some 2.4 GHz wireless sensors, high-voltage power lines, electric motors, ovens, microwave ovens, 2.4 GHz cordless phones, and wireless LAN access points.
