From the Manufacturer --------------------- • Certain features like Auto Tracking and SmartTrack may be disabled when using this accessory. Classic accessory bands are the recommended accessory for high intensity workouts and tracking. • Do not wear the Flex 2 Pendant accessory while ing or during high intensity activity, as doing so could create a choking hazard. • Flex 2 Pendant accessories contain magnets. Magnets may interfere with pacemakers, defibrillators, or other medical devices. Consult your physician and the manufacturer of your medical device before using to determine if these accessories are safe for you. If the accessories may be interfering with your pacemaker, defibrillator, or other medical device, do not wear the accessories.

Start by moving the device up to three finger widths above your wrist , then experiment with slightly lower placement. Keep it secure: The less your tracker moves during exercise, the more chance you have of maintaining a heart rate signal throughout the activity. Do not wear the band too tightly, as this can restrict blood flow and goes against our wear and care guidelines. Hold steady for ten seconds: High intensity exercises or activities that cause you to keep your wrist bent (like push-ups) or move your arms vigorously (like dance) may interfere with heart rate signals. If you stop seeing a signal during these types of activities, hold your wrist steady for ten seconds during breaks to get your reading.
