What’s in this document
We get you started quickly creating a Fitbit® account and making sure your tracker can
transfer the data it collects to your dashboard. The dashboard is where you’ll set goals,
analyze 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 help.fitbit.com.
Setting up your Fitbit FB409 & FB410
For the best experience we recommend using the Fitbit apps for iOS, Android, or
Windows 10. If you don’t have a mobile device, you can also use a Bluetooth®-enabled
Windows 10 PC or Mac. For non-Bluetooth options visit help.fitbit.com.
Your Fitbit account asks for information such as height, weight, and gender to make
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

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
FB409 & FB410 sync its data with your 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 FB409 & FB410 and then takes you to the fitbit.com dashboard.
Syncing your tracker data to your Fitbit account
When you start using your FB409 & FB410 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 FB409 &
FB410
This section tells you how best to wear, navigate, and charge your tracker. If you
bought an accessory wristband, you’ll also find instructions for taking off the original
band and putting on a different one.
Wrist placement
Review these tips to make sure you’re wearing your tracker for optimal results.
All-day wear and exercise
For all-day wear when you’re not exercising, your FB409 & FB410 should usually rest a
finger’s width below your wrist bone and lay flat, as you would normally wear a watch.
For optimized heart rate tracking keep these tips in mind:
1. Experiment with wearing the tracker higher on your wrist during exercise.
Because blood flow in your arm increases the farther up you go, moving the
tracker up a couple inches can improve the heart rate signal. Also, many
exercises such as bike riding or weight lifting cause you to bend your wrist
frequently, which is more likely to interfere with the heart rate signal if the
tracker is lower on your wrist.
2. Do not wear your tracker too tight; a tight band restricts blood flow, potentially
affecting the heart rate signal. That being said, the tracker should also be
slightly tighter (snug but not constricting) during exercise than during all-day
wear.
3. With high-intensity interval training or other activities where your wrist is
moving vigorously and non-rhythmically, the movement may limit the sensor’s
ability to provide a heart rate reading. Similarly, with exercises such as weight
lifting or rowing, your wrist muscles may flex in such a way that the band
tightens and loosens during exercise. If your tracker does not show a heart rate
reading, try relaxing your wrist and staying still briefly (about 10 seconds), after
which you should see a heart rate reading.
Wrist choice and dominant hand
For greater accuracy, your tracker needs to know which wrist you wear it on
(right or left) and which hand you consider dominant (right or left). Your dominant
hand is the one you usually write or throw with.
During setup you’re asked to choose the wrist where you're going to wear your tracker.
Should you later decide to move your tracker to the other wrist, change the Wrist
setting. You can also change your dominant hand at any time with the Handedness
setting. Both settings are found in the Account section of the Fitbit app or in the
Personal Info section of your fitbit.com dashboard settings.

quickly tap the screen.
Battery life and charging
Your fully charged FB409 & FB410 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 wake up your FB409 & FB410 you’ll see a low battery
icon after a few seconds. If you see a critical battery icon you’ll be unable to navigate
to any of the tracker screens until you charge your tracker. Your tracker continues to
track your activity until your battery runs out.
You can check your battery level at any time on the battery screen on your tracker or
on your Fitbit dashboard. To see the battery screen you must turn on the battery menu
item in the Fitbit app.
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. Clip the other end of the charging cable to the port on the back of the tracker.
The pins on the charging cable must lock securely with the port.
3. Make sure the button on your tracker is aligned with the button opening on the
charging cable. You’ll know the connection is secure when the tracker vibrates
and you see a battery icon on your tracker’s display. The battery icon disappears
after three seconds.
Charging fully takes about one to two hours. While the tracker charges, you can tap it
to check the battery level. A fully charged tracker shows a solid battery icon.
Care
It’s important to clean and dry your FB409 & FB410 regularly. For instructions and
more information, see http://www.fitbit.com/productcare.
Changing the wristband
The wristband has two separate bands (top and bottom) that you can swap with
accessory bands sold separately.
Removing a wristband
To remove the wristband:
1. Turn over your FB409 & FB410 and find the band latches—there’s one on each
end where the band meets the frame.
2. To release the latch, press down on the flat metal button on the strap.
3. Slide the band up to release it from the tracker.
4. Repeat on the other side.
If you’re having trouble removing the band or if it feels stuck, gently move the band
back and forth to release it.
Attaching a new wristband
Before you attach a new wristband, first identify the top and bottom bands. The top
band has a watch buckle at the end of it. The bottom band has notches and should be
attached on the side closest to the charging port.
To attach a band, slide it down on the end of the tracker until you feel it snap into
place.

Heart-rate zones help you target the training intensity of your choice. Your tracker
shows your current zone above your heart rate, and on your Fitbit dashboard you can
see your time spent in zones during a particular day or exercise. Three zones based on
American Heart Association recommendations are available by default, or you can
create a custom zone if you have a specific heart rate you’re targeting.
Default heart-rate zones
Default heart-rate zones are calculated using your estimated maximum heart rate.
Fitbit calculates your maximum heart rate with the common formula of 220 minus
your age.
The heart icon you see above your current heart rate tells you your zone. Refer to the
following table for an explanation of the different heart rate zones.

Custom heart-rate zones
Instead of using the default heart-rate zones, you can configure a custom zone or a
custom max heart rate if you have a specific target in mind. For example, elite athletes
might have a target that differs from the American Heart Association’s
recommendations for the average person. When you’re in your custom zone you’ll see
a solid heart on your tracker. When you’re not in the zone you’ll see an outline of a
heart.
For more details about heart rate tracking, including links to relevant American Heart
Rate Association information, see help.fitbit.com.
Tracking a daily activity goal
Your FB409 & FB410 tracks your progress towards a daily activity goal of your choice.
When you reach your goal, the tracker vibrates and shows a celebration.
Choosing a goal
By default your goal is 10,000 steps per day. You can change the goal to distance
traveled, calories burned, active minutes, or floors climbed 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.
Hourly

tracker:
• Not syncing despite successful setup
• Not responding to button presses or 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 UL-certified
USB wall charger.
2. Clip the other end of the charging cable to the port on the back of the tracker.
The pins on the charging cable must lock securely with the port.
3. Make sure the button on your tracker is aligned with the button opening on the
charging cable. You’ll know the connection is secure when the tracker vibrates
and you see a battery icon on your tracker’s display. Your FB409 & FB410 will
begin charging.
4. Press and hold the button on your tracker for four seconds. When you see the
Fitbit logo and the tracker vibrates, this means the tracker has restarted.
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.

Memory
FB409 & FB410 stores most minute-by-minute stats and exercise data for seven days.
It stores SmartTrack data for three days and summary totals for 30 days. Heart rate
data is stored at one-second intervals during exercise tracking and at five-second
intervals at all other times.
Stored data consists of steps, distance, calories burned, floors, active minutes, heart
rate, exercise, sleep, and stationary vs. active hours. FB409 & FB410 can store a
maximum of 10 hours of exercise data. This means that if you exercise for more than
10 hours and don’t sync your tracker, your exercise history will not include everything.
We recommend syncing your tracker at least once a day.
