From the Manufacturer
Auto Sleep Tracking/SmartTrack may be disabled with certain accessories. Classic bands are recommended for workouts/sleep. Avoid wearing the Flex 2 Pendant during sleep/high-intensity activity (choking hazard). Magnets in pendant accessories may interfere with medical devices—consult a physician before use.
Buying Guide
- Move it up: Wear higher on the wrist (3 finger-widths above the bone) for better heart rate signals.
- Keep it secure: Ensure the band stays snug but not tight to avoid restricted blood flow.
