Getting Started
What’s included
Your Fitbit Flex Wireless Activity + Sleep Wristband box includes:
•Flex tracker
•Charging cable
•Wireless sync dongle
•1 small and 1 large wristband
Flex tracker
Charging cable
Wireless sync
dongle
Wristbands
Putting on your Flex
Your Flex comes with a large and a small wristband. If you want to use the small
wristband, complete the next task before continuing. If you want to use the large
wristband, skip the next task and go directly to “Inserting the tracker into the
wristband” on page 2.
Moving the clasp from the large to small wristband
If you choose the small wristband, you’ll need to remove the clasp from the large
wristband and put it into the small wristband. To do so:
1. Push the clasp out with one thumb from the inside of the wristband.
2. Pull out the clasp.
3. Insert the clasp into the small wristband by pressing a few times with both
thumbs to ensure that the clasp is flat and in line with the wristband.

2
NOTE: 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 grey arrow facing up. Insert this end into the
wristband, with the arrow pointing toward the holes in the wristband.

3
Securing your wristband
1. Put on the wristband so the window of lights are closest to the outside of your
wrist and facing you.
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.

4
You’ll know your Flex 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.
Care and wearing tips
Keep the following tips in mind when caring for your Flex:
•Clean and dry the Flex regularly, particularly under the band.
•Wear your Flex band loosely enough to allow air circulation.
•Use skin care products sparingly on the areas of the wrist covered by the Flex.
•If you notice any signs of skin irritation or experience any discomfort, please
discontinue use.

5
Setting up your Flex
You can set up your Flex using a computer or one of our mobile apps for iOS,
Android, and Windows Phone.
Setting up your Flex with a computer
To set up your Flex using your computer, you’ll first install Fitbit Connect. Fitbit
Connect is the software application that connects (“pairs”) your Flex to your
Fitbit.com dashboard, where you can view your data, log food, and more.
Mac and PC requirements
Software
Mac OS 10.5 or later
Internet Connection
Hardware

Software
Windows XP, Vista, 7, 8
Internet Connection
Hardware
USB port
Downloading Fitbit Connect
1. Go to http://www.fitbit.com/setup.
2. Scroll down and click the pink Download button. If the button does not
correctly show your type of computer (for example, if it says “Download for
Mac” when you’re on a PC), choose the correct type before clicking the
button.
3. You’ll be prompted to open or save the installation file. Choose to save the file.
Installing Fitbit Connect and pairing your Flex
1. Plug your wireless sync dongle into your computer’s USB port and have your
charged tracker nearby.
2. Find the file you just downloaded. If you don’t see it in your Downloads list,
search for it using the file name:
-For Mac: Install Fitbit Connect.pkg
-For Windows: FitbitConnect_Win.exe
3. Once you find the file, double-click it to begin installing Fitbit Connect.
4. Follow the brief onscreen instructions to finish setting up. You’re ready to get
moving.
Syncing your Flex
Now that Fitbit Connect is installed, your Flex will automatically and wirelessly sync
with your computer every 20 minutes or so if the following requirements are met:

6
•Your Flex is within 15-20 feet of your computer and has new data to upload
(meaning if you haven’t moved, an automatic sync won’t occur).
•Your computer is powered on, awake, and connected to the Internet.
•The wireless sync dongle is inserted into a USB port and is recognized by the
computer.
When Flex syncs, your data is uploaded to your Fitbit.com dashboard. Flex holds
detailed minute-by-minute information for the most recent 7 days and daily activity
summaries for 30 days. For the most accurate dashboard possible, sync your Flex
regularly.
To manually synchronize your Flex with your dashboard, click the Fitbit Connect icon
located near the date and time on your computer and click Sync Now.
Setting up your Flex with a mobile device
You can set up and wirelessly sync your Flex using over 120 mobile devices that
support Bluetooth 4.0 technology. To see if your mobile device is compatible for
syncing with your Flex, visit www.fitbit.com/devices. If your device is listed, you can
then download our free iOS, Android, or Windows Phone apps. Once downloaded,
open the app and follow the setup instructions provided.
NOTE: If your mobile device is not compatible to sync via Bluetooth 4.0, you can still
use the Fitbit app to view your data and track your progress, you’ll just need
to set up and sync using a Mac or PC.

7
Using your Flex
Your Flex is designed to be most accurate when worn on your wrist.
Wearing on your dominant vs. non-dominant wrist
To get the most accurate reading from your Flex, make sure your account knows if
you’re wearing the wristband on your dominant or non-dominant wrist. Your
dominant wrist refers to handedness, that is, the hand that you use for activities such
as writing and throwing a ball.
To configure this setting:
1. Log in to Fitbit.com and click the gear icon in the top-right corner.
2. Click Settings > Devices.
3. Under Dominant Hand choose the correct setting.
4. Sync your tracker to save the change:
a. Click the Fitbit Connect icon near the date and time on your computer.
b. Click Sync Now.
Using your Flex in wet conditions
Your Flex is water-resistant, which means it is rain-proof and splash-proof and can
stand up to even the sweatiest workout.
Do not swim with your Flex. We also don't recommend showering with your Flex;
though the water won't hurt the device, wearing it 24/7 does not give your skin a
chance to breathe. Whenever you get your Flex wet, dry it thoroughly before putting
it back on.
Understanding the LED indicator lights
Your Flex features a display that consists of 5 LED indicator lights. The lights behave
differently depending on what the tracker is doing.
Goal tracking
The indicator lights illuminate as you hit 20% increments towards your goal. Tap your
Flex to see your progress. When you reach your goal, Flex will celebrate by buzzing
and flashing its lights.
Sleep mode
When you tap your Flex rapidly for one or two seconds to enter sleep mode, it will
vibrate and display two slowly dimming lights. During sleep mode, two blinking lights
alternate. After you tap your Flex rapidly to exit sleep mode, it will vibrate and flash
all five lights three times and then display a spinning light pattern.

8
Charging
While your Flex is charging, an indicator light will pulse to show the battery level
every few seconds. Each indicator light represents progress towards the total
charge. When the Flex has charged completely, all 5 indicator lights will blink.
Updating
If an update fails to complete, your Flex's LED indicator lights may cycle back and
forth repeatedly, from left to right, and your Flex no may longer respond to taps,
charging, or resets.
Alarms
When a silent alarm goes off, the Flex vibrates and the center light flashes.
Charging your Flex
Your Flex comes equipped with a rechargeable lithium-polymer battery.
With normal use, your Flex should last about five days before needing a charge. You
can check the level of your battery by logging in to Fitbit.com and clicking on the
gear icon on the top-right corner of the page.
To charge your Flex, plug the charging cable into the USB port on your computer.
Remove the tracker from the wristband, and insert it into the charging cable, with the
LED indicator lights facing up.
The LED indicator lights will progressively illuminate on your Flex as it charges. Each
light represents 20% of the maximum charge. Once all five lights pulse in unison, your
Flex will be fully charged. Charging completely can take up to three hours.

9
Tracking your Fitness with Flex
Your Flex tracks:
•Steps taken
•Calories burned
•Distance traveled
•Active minutes
•Time asleep
•Number of times awoken
Setting goals with Flex
Your Flex is designed to track your progress towards the fitness goal you choose.
Goals can be set for steps taken, calories burned, or distance traveled.
To choose the specific goal you want to track:
1. Log in to your Fitbit.com dashboard and click the gear icon in the top right
corner.
2. Click Settings > Devices.
3. Under Daily Goal Progress, choose the goal you would like to track.
4. Sync your Flex to send the new goal to your tracker.
Note: Your Flex starts tracking your goal for the next day at midnight, according to
the time zone you’ve selected for your account. The reset that occurs at
midnight does not delete the previous day’s data; all your data will appear on
your dashboard when you sync your tracker.
Once you’ve chosen which goal you want to track, you can set a specific value for
that goal on the Fitbit.com dashboard page or using the Fitbit app for mobile. For
example, instead of the default 10,000 steps per day, you may want your goal to be
15,000 per day. To change your goal value using your Fitbit.com dashboard:
1. Find the tile that corresponds to your goal.
2. Click the gear icon in the lower left corner of the tile.
3. Change your Daily Goal value.

10
Checking your goal progress
Tap your Flex twice to see the LED indicator lights indicate your progress towards
your goal.
Each fully lit indicator represents 20% of your total goal. A blinking light shows the
current segment of the goal you’re working on.
In the example below, two lights are solid and the third is blinking. This means you’ve
achieved between 40% and 60% of your overall goal.
When you reach your goal, your Flex will vibrate and flash the LED indicator lights to
celebrate.

11
Tracking sleep with Flex
Your Flex can track the length and quality of your sleep to help you improve your
sleeping habits.
To enter sleep mode, tap your Flex rapidly for one to two seconds. It will vibrate and
display two slowly dimming lights to indicate that sleep mode has begun.
NOTE: During sleep mode, your Flex will not display goal progress if you double tap.
Instead, it will alternate two blinking lights, back-and-forth, to indicate that
you are in sleep mode.
When you wake up, tap your Flex rapidly for one to two seconds to exit sleep mode.
Upon exiting sleep mode, your Flex will vibrate and flash all five LED indicator lights.
If you forget to put your Flex into sleep mode, you can always enter your sleep time
at http://www.fitbit.com/sleep. After creating a record, you will be able to view your
sleep efficiency. You can view your sleep data on the Fitbit.com dashboard or in the
Fitbit mobile app. If you choose, you can also set a goal for number of hours slept.

be configured to recur every day, or on particular days of the week.
