To charge it, remove the tracker from the band and place it in the charger until all 5 lights are solid. If you are having trouble, your tracker's charging contacts may be obstructed by microscopic dirt or debris that prevents them from making a good connection to the charger. Use hand sanitizer and a tissue or dampen a cotton swab with rubbing alcohol and carefully clean the charging contacts on your tracker. Do not submerge your tracker in water or use abrasive cleaners. Thoroughly dry your tracker before attempting to charge. Be sure to fully seat your tracker into the charger, with the charging contacts fully inserted into the charging cable enclosure. How do I reset my tracker? lf your tracker is not responding, it may be fixed by restarting. 1. Plug your charging cable into the USB port and insert your tracker into the charging cable. 2. Insert a paperclip into the small pinhole on the back of the charger. 3. Press on the pinhole for 3-4 seconds. Your Flex will now be reset. Take your tracker out of the charger and insert it back into the wristband. Can the wristband irritate my skin? The Flex wristband is made of a flexible, durable elastomer material similar to that used in many sports watches. It does not contain latex. The clasp is made of surgical-grade stainless steel and contains traces of nickel. As with any type of jewelry, some people may experience ies. Numerous factors can cause an y, such as a nickel sensitivity, reactions to bacteria that can accumulate in watch wristbands or other wearable devices, a reaction between the wristband and your soap or perspiration, or an y to the material of the wristband. If you notice any signs of skin or experience any discomfort, please discontinue use. 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.
