To find more information, tips, and troubleshooting, please browse our comprehensive articles at http://help.fitbit.com. 1 Putting on your Fitbit Flex 2 Your Flex 2 comes with a large and a small wristband. If you want to use the large wristband youll need to move the clasp from the small wristband. If you need help inserting the tracker into an accessory such as a necklace, bracelet, or clip, see help.fitbit.com. Moving the clasp from the small to large wristband If you choose to wear the large wristband, youll need to remove the clasp from the small wristband and put it into the large wristband:

If you dont have a mobile device you can also use a Bluetooth-enabled Windows 10 PC or Mac. While creating a Fitbit account youll be asked for personal information such as height, weight, and gender. We use your answers for various calculations, such as stride lengths to estimate distance and basal metabolic rate to estimate calorie burn. You have the option to share your age, height, or weight with Fitbit friends but the information you provide is always private by default.

The dashboard is where youll track progress, see your exercise history, track your sleep patterns, participate in challenges, and much more. We recommend syncing at least once a day. The Fitbit apps and Fitbit Connect use Bluetooth Low Energy (BLE) technology to sync with your Fitbit tracker. Each time you open the Fitbit app it syncs automatically if the paired tracker is nearby. You can also use the Sync Now option in the app at any time. Fitbit Connect syncs every 15 minutes if the tracker is within 20 feet of the computer. To force a sync, click the Fitbit Connect icon located near the date and time on your computer and choose Sync Now. 6 Getting to know your Fitbit Flex 2 This section tells you how best to wear, navigate, and recharge your tracker. Wearing on your dominant vs non-dominant wrist For greater accuracy, your tracker needs to know which wrist you wear it on. Your non-dominant wrist is the default setting for the tracker. If you wear your tracker on your dominant wrist instead (meaning, the hand you write with), change the default by going to the Account section of the Fitbit app or the Personal Info section in your fitbit.com settings. Understanding the indicator lights Your Flex 2 has five indicator lights that flash various patterns depending on what the tracker is doing. One light changes color while the other four are always white. First-time setup If you put your tracker in the charger before you set it up (pair), the tracker vibrates and all five lights flash. The top light changes color several times before flashing blue continuously. When you put the tracker in the wristband and begin the pairing process, all five lights flash in a looping pattern until youre prompted to double tap the tracker. When pairing is done, all five lights blink twice and youll feel two short vibrations. Charging While Flex 2 is charging, each pulsing indicator light represents progress towards the total charge in increments of 25%. When Flex 2 is completely charged, a green light flashes and then all five lights blink for three seconds before turning off. Updating We occasionally make free feature enhancements and product improvements available through firmware updates. During an update, all five lights on Flex 2 flash in a circular pattern. If an update cant finish, a blue light blinks and youll receive an alert in the Fitbit app. Low battery When your Flex 2 battery is low youll see a red light. 7 Activity goal tracking Tap your Flex 2 to see your progress towards your daily activity goal. Each solid white light represents 25% of your goal, meaning for example that if your goal is 10,000 steps and you see three white lights, youve gone at least 7500 steps. When you reach your goal Flex 2 vibrates and the lights flash in celebration. Alarms Flex 2 vibrates to wake you when a silent alarm goes off. Youll see a yellow light and three white lights for 30 seconds or until you dismiss the alarm. Call notifications When you receive a phone call, Flex 2 vibrates until you answer the call or double tap Flex 2 to dismiss the notification. While the phone is ringing youll see a purple light and four white lights Text notifications When you receive a text message Flex 2 vibrates once and youll see a blue light and two white lights. Reminders to move When you receive a reminder to move Flex 2 vibrates once and youll see an orange light and one white light. Battery life and charging Your fully charged Flex 2 has a battery life of up to five days. Battery life and charge cycles vary with use and other factors; actual results will vary. Determining your current battery level You can check your battery level on your Fitbit dashboard. When your battery is low Flex 2 shows a red light and TBD white lights.

8 Charging your tracker To charge your tracker:

1. Plug the charging cable into the USB port on your computer or a UL-certified USB wall charger. 2. Press the tracker into the compartment on the charging cable The pins on the charging cable must align with the corresponding pins on the back of the tracker and lock securely in place.

FPO [tracker going correctly into charging cable]

Charging fully takes about one to two hours. While the tracker charges, each white light that turns on represents 25% of the maximum charge. When Flex 2 has charged completely, youll see a green light and then all five lights will blink for three seconds before turning off. Care Its important to clean and dry your Flex 2 regularly. For instructions and more information see http://www.fitbit.com/productcare. Always remember to keep it clean; keep it dry; dont wear it too tight;

and give your wrist a rest. 9 Automatic Tracking with Fitbit Flex 2 Flex 2 continuously tracks your steps, distance, calories burned, and active minutes whenever you wear it. Sync your tracker and check your dashboard to see those stats and all the stats described below. Note: Flex 2 resets at midnight to begin a new day. Tracking sleep Wear your Flex 2 to bed to automatically track both your time spent asleep and your sleep quality. To see your sleep information, sync your tracker when you wake up and check your dashboard. The dashboard can recommend ideal bedtimes and wake times to help you improve your sleep cycle. You can even opt to be reminded nightly when its time to start winding down for bed. Note that Flex 2 can track your sleep only when youre wearing it on your wrist. Tracking a daily activity goal Your Flex 2 tracks your progress towards a daily activity goal of your choice. When you reach your goal, the tracker vibrates and flashes in celebration. Choosing a goal By default your goal is 10,000 steps per day. You can change the goal to distance traveled, calories burned, or active minutes and select the corresponding value you prefer. For example, you may want to keep steps as your goal but change the target from 10,000 to 20,000 steps. Seeing goal progress Tap Flex 2 twice to see your progress towards your goal. FPO [tracker on wrist with motion of double tapping the tracker]

Each white light represents 25% of your total goal. A blinking light shows the current segment of the goal youre working on. 10 Tracking exercise The SmartTrack feature on Flex 2 automatically detects and records exercise details such as the number of laps you swim, the distance you run, and much more. When you sync Flex 2 after a workout youll find your results in the exercise history section of your Fitbit dashboard. By default, SmartTrack detects continuous movement at least 15 minutes in length. You can increase or decrease the minimum duration or disable SmartTrack for one or more exercise types. For more information about customizing and using SmartTrack, see help.fitbit.com. Note: SmartTrack requires that you wear Flex 2 on your wrist. When swimming, only use the wristband that came with Flex 2 or another elastomer band in a different color. Metal and other accessory materials are not designed for swimming. Tracking stationary time Flex 2 helps keep you active throughout the day by keeping track of when youre stationary and reminding you to move. If you havent walked at least 250 steps in a given hour, at ten minutes before the hour youll feel a vibration and see a light pattern reminding you to walk. When you meet the 250-step goal after receiving a reminder, youll feel a second vibration.

Reminder to move light pattern Note that Flex 2 can track stationary time and remind you to move when only youre wearing it on your wrist. 11 Using Silent Alarms Flex 2 can gently vibrate to wake or alert you with a silent alarm. On your Fitbit dashboard you can set up to eight alarms to recur every day or on particular days of the week. When the alarm goes off, simply double tap to dismiss.
