Tips for Erratic Heart Rate Data

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

  • Clean and dry your arm before putting on the watch.
  • Avoid wearing sunscreen, lotion, and insect repellent under the watch.
  • Avoid scratching the heart rate sensor on the back of the watch.
  • Wear the watch above your wrist bone. The watch should be snug but comfortable.
  • Wait until the Heart rate symbol icon is solid before starting your activity.
  • Warm up for 5 to 10 minutes and get a heart rate reading before starting your activity.
    NOTE: In cold environments, warm up indoors.
  • Rinse the watch with fresh water after each workout.
  • While exercising, use a silicone band.
