Welcome to Fitbit FB415, an all-day companion that lasts 4+ days and uses
personalized insights and more to help you reach your goals. Take a moment to
review our complete safety information at http://www.fitbit.com/safety.

What's in the box

Your FB415 box includes:

FB415's detachable wristbands come in a variety of colors and materials, sold
separately.

What's in this manual

We'll explain how to create a Fitbit® account and make sure your watch 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 FB415, you're ready to
start moving.

Next, we'll explain how to find and use the features that interest you and how to
adjust your preferences. For more information, tips, and troubleshooting, browse
our comprehensive help content at help.fitbit.com.

Set up Fitbit FB415

For the best experience, use the Fitbit app for iOS, Android, or Windows 10. If you
don’t have a smartphone or tablet, you can also use a Bluetooth-enabled Windows
10 PC.

Your Fitbit account asks for information such as height, weight, and sex in order
to calculate your stride length and to estimate distance, basal metabolic rate, and
calorie burn. When you set up your account, your name and photos are visible to
all other Fitbit users. You have the option to share other information, but most of
the information you provide is private by default.

Charge FB415

A fully charged FB415 has a battery life of up to 4+ days. Battery life and charge
cycles vary with use and other factors; actual results will vary.

To charge FB415:

1. Plug the charging cradle into the USB port on your computer or a UL­certified USB wall charger.

2. The charging cradle uses a spring clip to hold FB415 in place while charging.
Pinch the spring clip and place FB415 in the charging cradle. The pins on the
charging cradle must align with the gold contacts on the back of the watch.
The connection is secure when the percent charged appears on screen.

7

While the watch charges, tap the screen to check the battery level. Tap the screen
twice to use FB415 while it charges.

Set up with your phone or tablet

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

To get started:

8

1. Find the Fitbit app in one of the locations below, depending on your device.
If you're unsure if the Fitbit app is compatible with your phone or tablet, see

fitbit.com/devices.

• Apple App Store for iOS devices such as an iPhone or iPad.

• Google Play Store for Android devices such as the Samsung Galaxy S8

and Google Pixel.

• Microsoft Store for Windows 10 devices such as the Lumia phone or
Surface tablet.

2. Install the app. If you don't have an account with the store, you must create
one before you can download the app.

3. 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 log in to your
existing account.

4. Continue following the on-screen instructions to connect, or "pair," FB415 to
your phone or tablet. Pairing makes sure the watch and phone or tablet can
communicate with one another (sync data back and forth).

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

Set up with your Windows 10 PC

If you don't have a smartphone, you can set up and sync FB415 using a Bluetooth­enabled Windows 10 PC and the Fitbit app.

To get the Fitbit app for your computer:

1. Click the Start button on your PC and open the Microsoft Store.

2. Search for "Fitbit app". After you find it, click Free to download the app to
your computer.

3. If you've never downloaded an app to your computer, you'll be prompted to
create an account with the Microsoft Store.

4. Click Microsoft account to sign in with your existing Microsoft account. If
you don't already have an account with Microsoft, follow the on-screen
instructions to create a new account.

5. When the app is installed, open it and click Join Fitbit to be guided through
a series of questions that help you create your Fitbit account, or log in to
your existing account.

6. Continue following the on-screen instructions to connect, or "pair," FB415 to
your computer. Pairing makes sure the watch and computer can
communicate with one another (sync data back and forth).

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

Sync data to your Fitbit account

Regularly sync FB415 with the Fitbit app to transfer data to your dashboard. The
dashboard is where you'll track your progress, see exercise history, track your

9

sleep patterns, log food and water, identify trends, participate in challenges, and
much more. We recommend syncing at least once a day.

The Fitbit app uses Bluetooth Low Energy technology to sync data with FB415 and
to update apps installed on your watch.

Each time you open the Fitbit app, FB415 syncs automatically when it's nearby.
FB415 also syncs with the app periodically if All-Day Sync is on. To turn on this
feature:

From the Fitbit app dashboard, tap or click the Account icon ( ) > FB415 tile
> All-Day Sync.

You can also use the Sync Now option in the app at any time.

Wear FB415

Place FB415 around your wrist. The side of the watch marked with "fitbit" should
be on the bottom of your wrist. If you need to attach a different size wristband, or
if you purchased an accessory wristband, you'll find instructions in "Change the

wristband” on page 10.

Placement for all-day wear vs exercise

When you're not exercising, wear FB415 a finger's width below your wrist bone.

For optimized heart-rate tracking while exercising, keep these tips in mind:

• Try wearing FB415 higher on your wrist during exercise for an improved fit
and more accurate heart-rate reading. Many exercises, such as bike riding
or weight lifting, cause you to bend your wrist frequently, which can
interfere with the heart-rate signal if the watch is lower on your wrist.

10

• Make sure the watch is in contact with your skin.

• Don't wear your watch too tight; a tight band restricts blood flow, potentially

affecting the heart-rate signal. However, the watch should be slightly tighter
(snug but not constricting) during exercise than during all-day wear.

• 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. If your watch doesn't show a
heart-rate reading, try relaxing your wrist and staying still briefly (about 10
seconds). You should see a heart-rate reading.

Handedness

For greater accuracy, you must specify whether you wear FB415 on your dominant
or non-dominant hand. Your dominant hand is the one you use for writing and
eating. By default, the Wrist setting is set to non-dominant. If you wear FB415 on
your dominant hand, change the Wrist setting in the Fitbit app.

Change the wristband

FB415 comes with a small wristband attached and an additional large bottom
band in the box. Both the top and bottom bands can be swapped with accessory
bands, sold separately. For wristband measurements, see Wristband size on page

44.

Remove a wristband

To remove the wristband:

1. Turn FB415 over and find the quick-release lever—there's one on each end
where the band meets the frame.

2. To release the band, push the quick-release lever inward.

11

3. Gently pull the band away from the watch to release it.

4. Repeat on the other side.

Attach a wristband

To attach a wristband:

1. Slide the pin (the side opposite the quick-release lever) into the notch on the
watch. The band with the clasp attaches to the top of the watch.

2. While pressing the quick-release lever inward, slide the other end of the
band into place.

12

3. When both ends of the pin are inserted, release the quick-release lever.

13

Track a daily activity goal

FB415 tracks your progress towards a daily activity goal of your choice. When you
reach your goal, the watch vibrates and shows a celebration.

31

Choose a goal

By default, your goal is 10,000 steps per day, but you may have changed this goal
during setup. You can change the goal to distance traveled, calories burned, or
active minutes and select a corresponding value. For example, you may want to
keep steps as your goal but change the target from 10,000 to 20,000 steps.

For instructions on how to change your goal, see help.fitbit.com.

See goal progress

For information on how to see detailed progress toward your goal, see See See

your stats on page 29

Track your hourly activity

FB415 helps you stay 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 10 minutes before the
hour you'll feel a vibration reminding you to walk. When you meet the 250-step
goal after receiving the reminder, you'll feel a second vibration and see a
congratulatory message.

For more information on hourly activity, including how to customize the hours
you receive reminders, see help.fitbit.com.

Track your sleep

Wear FB415 to bed to automatically track your time asleep and sleep stages. To
see your sleep stats, sync your watch when you wake up and check your
dashboard.

For more information about sleep tracking, see help.fitbit.com.

Set a sleep goal

By default, you have a sleep goal of 8 hours of sleep per night. Customize this
goal to meet your needs.

32

For more information about your sleep goal, including how to change it, see

help.fitbit.com.

Set a bedtime reminder

The Fitbit dashboard can recommend consistent bedtimes and wake times to help
you improve the consistency of your sleep cycle. You can choose to be reminded
nightly when it's time to start getting ready for bed.

For more information about how to set bedtime reminders, see help.fitbit.com.

Learn about your sleep habits

FB415 tracks several sleep metrics including when you go to bed, how long you're
asleep, and your time spent in each sleep stage. When you use FB415 with the
Fitbit dashboard, your watch can help you understand how your sleep patterns
compare to others of the same sex and age range.

For more information about sleep stages, see help.fitbit.com.

Custom heart-rate zones

Instead of using the default heart-rate zones, you can set 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

40

recommendations for the average person. When you're in your custom zone, you'll
see a solid heart on your watch. When you're not in the zone, you'll see an outline
of a heart.

any new Fitbit OS updates.

Restart FB415

To restart your watch, press and hold the button for a few seconds until you see
the Fitbit logo on the screen

Restarting your watch reboots the device but does not delete any data.

Erase FB415

A factory reset erases all apps and personal data from FB415. If you want to give
FB415 to another person or wish to return it for a refund, first complete a factory
reset:

On FB415, open the Settings app ( ) > About > Factory Reset.

Update FB415

We make free feature enhancements and product improvements available through
OS updates. We recommend keeping FB415 up to date.

When an update is available, you'll see a notification in the Fitbit app prompting
you to update. When the update starts, a progress bar appears on FB415 and in
the Fitbit app until the update is complete. For best results, make sure your watch
is charged.

Troubleshooting

If your watch is not working properly, review our troubleshooting guidance below.
Visit help.fitbit.com for more information.

Heart-rate signal missing

FB415 continuously tracks your heart rate while you're exercising and throughout
the day. Occasionally, the heart-rate sensor on your watch may have difficulty
finding a good signal. When this happens, you'll see dashed lines where your
current heart rate usually appears.

44

If you're not getting a heart-rate signal, first make sure you're wearing your watch
correctly, either by moving it higher or lower on your wrist or by tightening or
loosening the band. FB415 should be in contact with your skin. After holding your
arm still and straight for a short time, you should see your heart rate again.

If the heart rate signal is still missing, open the Settings app ( ) on your watch
and make sure Heart Rate is set to On.

GPS signal missing

Environmental factors including tall buildings, dense forest, steep hills, and even
thick cloud cover can interfere with your phone's ability to connect to
GPS satellites. If your phone is searching for a GPS signal during an exercise, you'll
see "connecting" appear at the top of the screen.

For best results, wait for your phone to find the signal before you start your
workout.

Unexpected behavior

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

• Not syncing despite successful setup

• Not responding to taps despite being charged

• Not tracking your steps or other data

For instructions on how to restart your watch, see Restart FB415 on page 43.
