FREQUENTLY ASKED QUESTIONS

What mobile devices are supported for syncing?

The Fitbit Flex can sync directly to select iOS and Android devices. IOS: iPhone 4S, iPhone 5, 5S, 5C, iPod Touch (5th gen.), iPad 3, iPad 4, iPad mini. Android: Samsung Galaxy Note 10.1, Samsung Galaxy Note II, Samsung Galaxy S III, Samsung Galaxy S4

How do I charge my flex?

Your tracker battery lasts for about 5 days. 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 allergies. Numerous factors can cause an allergy, 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 allergy to the material of the wristband. If you notice any signs of skin irritation or experience any discomfort, please discontinue use.

From the Manufacturer

• Certain features like Auto Sleep Tracking and SmartTrack may be disabled when using this accessory. Classic accessory bands are the recommended accessory for high intensity workouts and sleep tracking. • Do not wear the Flex 2 Pendant accessory while sleeping 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.

Important information

Safety Information
• Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear. • If you have eczema, allergies or asthma you may be more likely to experience a skin irritation or allergy from a wearable device. • Whether you have the conditions above or not, if you start to experience redness or skin irritation on your wrist, remove your device. If symptoms persist longer than 2-3 days of not using your device, contact a dermatologist. • If you sweat for more than two hours while wearing your Fitbit band, be sure to wash your band and your wrist using the directions above to avoid skin irritation.

Indications:
• Make sure your band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist. • If you use Fitbit Charge HR , Fitbit Blaze or Fitbit Surge , for better heart rate readings during exercise, we suggest wearing the band so it’s secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise.

Directions:
• While Fitbit devices are water resistant*, it’s not good for your skin to wear a wet band for long periods of time. • If your elastomer band gets wet—like after sweating or showering—rinse and dry it thoroughly before putting it back on your wrist. • Be sure your skin is dry before you put your band back on. If Fitbit Blaze gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Give your wrist a rest by taking the band off every now and then, and regularly clean your band and wrist. • Even though Fitbit Flex 2 is swim-proof, it’s important to thoroughly dry your classic elastomer band and tracker, and remove any debris from your device after wear in the water, to avoid skin irritation. Please note that non-elastomer accessories should not be worn in water.
