What's in this document

We get you started quickly by creating a Fitbit® account and ensuring your tracker can transfer the data it collects to your Fitbit dashboard. The dashboard is where you'll set goals, analyze your historical data, identify trends, log food and water, keep up with friends, and much more. As soon as you're done setting up your tracker, you're ready to start moving.

Next, we explain how to find and use the features that interest you and adjust your preferences. To find more information, tips, and troubleshooting, please browse our comprehensive articles at http://help.fitbit.com.

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 you'll need to move the clasp from the small wristband.

If you need help inserting the tracker into an accessory such as a pendant, see help.fitbit.com.

Moving the clasp from the small to large wristband

If you choose to wear the large wristband, you'll need to remove the clasp from the small wristband and put it into the large wristband:

1. Push the clasp out from the inside of the wristband. You may find it helpful to first remove the square peg, followed by the round peg.
2. Pull out the clasp.
3. Insert the clasp into another wristband by lining up the square peg with the square hole and the round peg with the round hole and pressing firmly until both pegs are completely through the holes and snap into place.

NOTE: You may need to wiggle the pegs back and forth to get them to snap into place. If there is a bulge on the inside of the band between the two inside prongs of the clasp, find a small object like a credit card to push it flat.

Inserting the tracker into the wristband

Hold the tracker in your hand with the back of the tracker facing up. Find the dot on the back of the tracker. Insert this end into the side of the wristband that has a corresponding dot.

Securing your wristband

1. Put on the wristband so the colored LED light is closest to the outside of your wrist.
2. Align both ends of the wristband so they are directly overlapping each other with the clasp over the two holes that best fit your wrist.
   
3. Squeeze both the clasp and the wristband between your thumb and forefinger until you hear a click.
   
   You'll know your Flex 2 wristband is securely fastened if both ends of the wristband are fully inserted.
   
   NOTE: If you're having trouble, try securing the wristband off your wrist to get a feel for how it securely clasps and then try again on your wrist.

Setting up your Fitbit Flex 2

We recommend using the Fitbit apps for iOS, Android, or Windows 10 to set up your tracker and make the most of the Fitbit experience. If you don't have a mobile device you can also use a Bluetooth®-enabled Windows 10 PC or Mac. For syncing options if you don't have mobile device or Bluetooth-enabled Windows 10 PC or Mac, see help.fitbit.com

While creating a Fitbit account you'll 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 private by default.

Setting up your tracker on your mobile device

The free Fitbit app is compatible with more than 200 mobile devices that support iOS, Android, and Windows 10 operating systems.

To get started:

1. Make sure the Fitbit app is compatible with your mobile device by checking http://www.fitbit.com/devices.
2. Find the Fitbit app in one of these locations, depending on your device:
   • The Apple® App Store® for iOS devices such as an iPhone®or iPad®.
   • The Google Play™ Store for Android devices such as the Samsung® Galaxy® S5 and Motorola Droid Turbo.
   • The Microsoft® Windows Store for Windows 10 mobile devices such as the Lumia™ phone or Surface™ tablet.
3. Install the app. Note that if you don't have an account with the store you'll be required to create one before you can download the app.
4. When the app is installed, open it and tap Join Fitbit to be guided through a series of questions that help you create your Fitbit account, or login to your existing account.
5. Continue following the onscreen instructions to connect, or pair, your Flex 2 to your mobile device. Pairing makes sure the tracker and mobile device can communicate with one another (sync data back and forth).

When you're done pairing, read through the guide about your new tracker and then explore the Fitbit dashboard.

Setting up your tracker on your Windows 10 PC

If you don't have a mobile device, you can set up and sync your tracker using a Bluetooth-enabled Windows 10 PC. The same Fitbit app that is available for Windows 10 mobile devices is available for your computer.

To get the Fitbit app for your computer:

Click the Start button on your PC and open the Windows Store (called Store).

1. Search for "Fitbit app" and when you find it click Free to download the app to your computer.
2. If you've never downloaded an app to your computer you'll be prompted to create an account with the Windows Store.
3. Click Microsoft account to sign in with your existing Microsoft account. If you don't already have an account with Microsoft, follow the onscreen instructions to create a new account.
4. Open the app after it's done downloading.
5. Click Join Fitbit to be guided through a series of questions that help you create a Fitbit account, or login to your existing account.
6. Continue following the onscreen instructions to connect, or pair, your Flex 2 with the Windows 10 app. Pairing makes sure the tracker and app can communicate with one another (sync data back and forth).

When you're done pairing, read through the guide about your new tracker and then explore the Fitbit dashboard.

Setting up your tracker on your Mac

If you don't have a compatible mobile device, you can set up your tracker with a Bluetooth-enabled Mac and use the fitbit.com dashboard to see your stats. To use this method you'll first install a free software application called Fitbit Connect that lets Flex 2 sync its data with your www.fitbit.com dashboard.

To install Fitbit Connect and set up your tracker:

1. Go to http://www.fitbit.com/setup.
2. Scroll down and click the option to download. If the button does not correctly show your type of computer (for example, if it says "Download for Mac"), choose the correct type, then click the button.
3. You'll see an option to open or save a file; choose open. After several seconds you'll see an option to install Fitbit Connect.
   
4. Double-click Install Fitbit Connect.pkg. The Fitbit Connect installer opens.
5. Click Continue to move through the installer.
6. When prompted, choose Set up a New Fitbit Device.
7. Follow the onscreen instructions to create a Fitbit account, or login to your existing account, and connect your tracker with Fitbit Connect.

When you're done with the setup steps, Fitbit guides you through an introduction to your new Flex 2 and then takes you to the fitbit.com dashboard.

Syncing your tracker data to your Fitbit account

When you start using your Flex 2 you'll need to regularly sync it with your Fitbit dashboard. The dashboard is where you'll 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.

Getting to know your Fitbit Flex 2

This section tells you how best to wear, navigate, and recharge your tracker.

Wrist choice and dominant hand

For greater accuracy, your tracker needs to know which wrist you wear it on (dominant or non-dominant). Your dominant hand is the one you usually write or throw with.

By default, your tracker is setup to be worn on your non-dominant wrist. Should you later decide to move your tracker to the other wrist, change the Wrist setting in the Account section of the Fitbit app or in the Personal Info section of your fitbit.com dashboard 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

The first time you put your tracker in the charger before you set it up (pair), your Flex 2 will flash and vibrate to greet you. 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 you're prompted to double tap the tracker. When pairing is done, all five lights blink twice and you'll 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 shine for a few 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 an upward pattern. If an update can't finish, you'll see your progress toward today's goal and receive an alert in the Fitbit app.

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 four white lights, you've gone at least 7500 steps. When you reach your goal Flex 2 vibrates and the lights flash in celebration. After you reach your goal and you check your goal progress you'll see a flashing green light and four white lights

Alarms

Flex 2 vibrates to wake you if you set a silent alarm. You'll also see a yellow light and three white lights for 30 seconds or until you dismiss the alarm.

Call notifications

If you have call notifications enabled and you receive a phone call with your phone nearby, Flex 2 vibrates two times and you'll see a pattern of one blue light and four white lights repeated four times, or until you answer the call or double tap Flex 2 to dismiss the notification.

Text notifications

If you have text notifications enabled and you receive a text message with your phone nearby, Flex 2 vibrates once and you'll see a blue light and one white light.

Reminders to move

When you receive a reminder to move Flex 2 vibrates twice and you'll see a magenta light and two white lights. When you meet the 250-step goal after receiving a reminder, you'll feel a second vibration and see a celebratory light pattern.

Low battery

When your tracker is in a low battery state, usually when you have about a day of battery life remaining, you'll see a flashing red light after you see your goal progress.

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.

Finding your current battery level

If your battery is low, when you check your goal progress on your Flex 2, you'll see a flashing red light after you see your goal progress.

You can also check your battery level on your Fitbit dashboard.

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. You'll know the connection is secure when the tracker vibrates and you see the indicator lights blinking, indicating your progress towards a total charge.
   

Charging fully takes about two to three hours. While the tracker charges, each white light that turns on represents 25% of the maximum charge. When Flex 2 has charged completely, you'll see a green light and then all five lights will shine for a few seconds before turning off.

If you don't see any lights flashing, you can double-tap your tracker to check the charging progress. You'll know your tracker is fully charged when you see one green and four white indicator lights.

Care

It's 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; don't wear it too tight; and give your wrist a rest.

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 pendant and bangle accessories should not be worn in water.

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.

Your Fitbit dashboard can recommend consistent bedtimes and wake times to help you improve your sleep cycle. You can even choose to be reminded nightly when it's time to start winding down for bed.

Note: Automatic sleep tracking may be disabled when using the pendant accessory. Do not wear the Flex 2 pendant accessory while sleeping; classic accessory bands are the recommended accessory for sleep tracking.

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.

Each white light represents 25% of your total goal. A blinking light shows the current segment of the goal you're working on.

Tracking exercise

The SmartTrack™ feature on Flex 2 automatically tracks walking, running, cycling, aerobic exercises, and more. When you sync Flex 2 after a workout you'll 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: Certain features like automatic sleep tracking and SmartTrack may be disabled when using the necklace accessory. Do not wear the Flex 2 necklace accessory while sleeping or during high-intensity activity. Classic accessory bands are the recommended accessory for high-intensity workouts and sleep tracking. Please note that non-elastomer accessories should not be worn in water.

Tracking hourly activity

Flex 2 helps keep you active throughout the day by keeping track of when you're stationary and reminding you to move.

If you haven't walked at least 250 steps in a given hour, at ten minutes before the hour you'll feel a vibration and see a light pattern reminding you to walk. When you meet the 250-step goal after receiving a reminder, you'll feel a second vibration and see a celebratory light pattern.

For more information about reminders to move, including information on how to turn them on, see help.fitbit.com.

Reminder to move light pattern

Using Silent Alarms

Flex 2 can gently vibrate to wake or alert you with a silent alarm. You can set up to eight alarms to recur every day or on particular days of the week only. When the alarm goes off, simply double tap to dismiss.

For more information about customizing and using silent alarms, see help.fitbit.com.

Receiving Call and Text Notifications

Over 200 compatible iOS and Android mobile devices let you receive incoming phone call and text message notifications on your Flex 2 when your mobile device is nearby. To determine whether your device supports this feature, go to http://www.fitbit.com/devices. Note that notifications aren't available with the Fitbit app for Windows 10.

Enabling notifications

Before you turn on notifications in the Fitbit app, make sure that Bluetooth is on and that your mobile device is capable of sending notifications (often under Settings > Notifications).

For more information about making sure your mobile device permits notifications, see help.fitbit.com.

To turn on call or text notifications:

1. With your tracker nearby, tap Account on the Fitbit dashboard.
2. Tap the Flex 2 tile.
3. Tap Notifications and turn on or off any combination of call or text notifications.
4. Follow the onscreen instructions to connect (bond) your mobile device with your tracker.

After notifications are enabled, "Flex 2" appears in the list of Bluetooth devices paired to your mobile device.

Note: If this is your first time setting up notifications on your Android mobile device, for detailed instructions, see help.fitbit.com

Recognizing incoming notifications

If your tracker and mobile device are within 30 feet of each other, a call or text message causes the tracker to show a light pattern and vibrate.

For phone calls, Flex 2 vibrates two times or until you answer the call or double tap your tracker. While the phone is ringing you'll see a blue light and four white lights, repeated up to four times.

Call notification light pattern

For text messages Flex 2 vibrates once and repeats three times the light pattern of one blue light and one white light. To dismiss the notification double-tap your tracker.

Text notification light pattern

Updating your Fitbit Flex 2

We occasionally make free feature enhancements and product improvements available through firmware updates. We recommend keeping your Flex 2 up to date.

When a firmware update is available you'll see a notification in the Fitbit app prompting you to update. When the update starts, the lights on Flex 2 flash and a progress bar appears in the app. You'll see a confirmation message in the app when the update is done.

Note: Updating your Flex 2 takes several minutes and may be demanding on the battery. For this reason we recommend updating while your tracker is fully charged or plugged into the charging cable.

Troubleshooting your Fitbit Flex 2

If you experience one of the following problems, it may be fixed by restarting your tracker:

• Not syncing despite successful setup
• Not responding to taps despite being charged
• Not tracking your steps or other data

Note: Restarting your tracker reboots the device but does not delete any data.

To restart your tracker:

1. Plug the charging cable into the USB port on your computer or a ULcertified USB wall charger.
2. Remove the tracker from the wristband and 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. You'll know the connection is secure when the tracker vibrates and you see the indicator lights blinking, indicating your progress towards a total charge. Your Flex 2 will begin charging.
   
3. Find the button on the charging cable and press it three times within five seconds. The button is under the tracker compartment.
   The tracker vibrates each time you press the button. After the third button press, wait for about five seconds for all the lights to flash at once, this means the tracker has restarted.
   Note that the light flash happens quickly and you may not notice it. Your tracker resumes charging after a restart and you will see the normal blinking of the indicator lights indicating your progress towards a total charge.

After your tracker restarts you can unplug it from the charging cable and put it back on. For additional troubleshooting or to contact Customer Support, see help.fitbit.com.
