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
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.
