What's in the box

Your Fitbit Charge 3 box includes:

Tracker with small wristband (color

and material vary)

The detachable wristbands on Charge 3 come in a variety of colors and materials,
sold separately.

Charging cable

Additional large band (color

and material vary)

Set up Fitbit Charge 3

For the best experience, use the Fitbit app for iPhones and iPads, Android phones,
or Windows 10 devices. If you don’t have a compatible phone or tablet, use a
Bluetooth-enabled Windows 10 PC. Keep in mind that a phone is required for call,
text, calendar, and smartphone app notifications.

Your Fitbit account asks for information such as height, weight, and sex to calculate
your stride length and to estimate distance, basal metabolic rate, and calorie burn.
When you set up your account, your first name, last initial, 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 Charge 3

A fully-charged Charge 3 has a battery life of up to 7 days. Battery life and charge
cycles vary with use and other factors; actual results will vary.

To charge your Charge 3:

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. A battery
icon appears on the screen.

7

Charging fully takes about 1-2 hours. While the tracker charges, you can press the
button to check the battery level. A fully-charged tracker shows a solid battery icon
with a smile.

Set up with your phone or tablet

The free Fitbit app is compatible with most iPhones and iPads, Android phones,
and Windows 10 devices. If you're unsure if the Fitbit app is compatible with your
device, see fitbit.com/devices.

To get started:

1. Find the Fitbit app in one of the locations below, depending on your device.

l Apple App Store for iPhones and iPads
l Google Play Store for Android phones
l Microsoft Store for Windows 10 devices

2. Install the app.

8

3. When the app is installed, open it and tap Join Fitbit to be guided through a
series of questions that help you create an account.

4. Continue to follow the on-screen instructions to connect Charge 3 to your
Fitbit account.

When you're done with setup, read through the guide to learn more about your
new tracker and then explore the Fitbit app.

Set up with your Windows 10 PC

If you don't have a compatible phone, you can set up and sync Charge 3 with a
Bluetooth-enabled 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. 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.

4. Open the app and log in to your account, or click Join Fitbit to be guided
through a series of questions that help you create an account.

5. Continue to follow the on-screen instructions to connectCharge 3 to your
Fitbit account.

When you're done with setup, read through the guide to learn more about your
new tracker and then explore the Fitbit app.

See your data in the Fitbit app

Sync Charge 3 to transfer your data to the Fitbit app, where you can view your
exercise and sleep data, log food and water, participate in challenges, and more.
We recommend syncing at least once a day.

9

Each time you open the Fitbit app, Charge 3 syncs automatically when it's nearby.
Charge 3 also syncs with the app periodically if All-Day Sync is on. To turn on this
feature:

From the Fitbit app dashboard, tap the Account icon ( ) >Charge 3 tile >All­Day Sync.

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

10

Wear Charge 3

PlaceCharge 3 around 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13.

Placement for all-day wear vs exercise

When you're not exercising, wear Charge 3 a finger's width below your wrist bone.

For optimized heart-rate tracking while exercising:

l Try wearing Charge 3 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 tracker is lower on your wrist.

11

l Make sure the tracker is in contact with your skin.
l Don't wear your tracker too tight; a tight band restricts blood flow, potentially

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

l 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 tracker doesn't show a
heart-rate reading, try relaxing your wrist and staying still briefly.

12

Change the wristband

Charge 3 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54.

Remove a wristband

To remove the wristband:

1. Turn over Charge 3 and find the wristband latches.

2. To release the latch, press down on the flat button on the wristband.

3. Gently pull the wristband away from the tracker to release it.

4. Repeat on the other side.

13

Attach a new wristband

To attach a new wristband, press it into the end of the tracker until you feel it snap
into place.

If you have trouble attaching the wristband or if it feels loose, gently move the
wristband back and forth to make sure it's attached to the tracker.

This is a low-to-medium intensity exercise zone. This zone
may be a good place to start for those new to exercise. It's
called the Fat Burn zone because a higher percentage of
calories are burned from fat, but the total calorie burn rate
is lower.

This is a medium-to-high intensity exercise zone. In this
zone you're pushing yourself but not straining. For most
people this is the exercise zone to target.

This is a high-intensity exercise zone. This zone is for short
intense sessions that improve performance and speed.

Custom heart-rate zones

Configure a custom heart-rate zone or a custom max heart rate in the Fitbit app 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 most
people.

For more information, including links to relevant American Heart Rate Association
information, see help.fitbit.com.

You can add up to 5 payment cards to the Wallet and choose which card to set as
the default payment option on your tracker.

Make purchases

Make purchases using Fitbit Pay at any store that accepts contactless payments. To
determine if the store accepts Fitbit Pay, look for the symbol below on the payment
terminal:

To pay with Charge 3:

All customers except those in Australia:

1. When you're ready to pay, press and hold the button on your tracker for 2
seconds. Swipe to the Payments screen if it's not shown.

2. If prompted, enter your 4-digit tracker PINcode. Your default card appears on
the screen.

3. To pay with your default card, hold your wrist near the payment terminal. To
pay with a different card, tap to find the card you want to use and then hold
your wrist near the payment terminal.

44

When the payment succeeds, your tracker vibrates and you'll see a confirmation on
the screen.

If the payment terminal doesn't recognize Fitbit Pay, make sure the tracker face is
near the reader and that the cashier knows you're using a contactless payment.

Customers in Australia:

1. If you have a credit or debit card from an Australian bank, hold your tracker
near the payment terminal to pay. If your card is from a bank outside of
Australia, or if you wish to pay with a card that is not your default card,
complete steps 1-3 in the section above.

2. If prompted, enter your 4-digit tracker PINcode.

3. If the purchase amount exceeds $100 AU, follow the instructions on the
payment terminal. If prompted for a PIN code, enter the PIN code for your
card (not your tracker).

If the payment terminal doesn't recognize Fitbit Pay, make sure the tracker face is
near the reader and that the cashier knows you're using a contactless payment.

For added security, you must wear Charge 3 on your wrist to use Fitbit Pay.

45

Update, Restart, and Erase

Learn how to update, restart, and erase Charge 3.

Restart Charge 3

If you can’t sync Charge 3, or if you have trouble with connected GPS or tracking
your stats, you can restart your tracker from your wrist. From the clock face, swipe
to Settings and tap About > Reboot Device.

If your tracker is unresponsive:

1. Plug the charging cable into the USBport on a 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. Press and hold the button on your tracker for 8 seconds. Release the button.
When you see a smiley face and the tracker vibrates, the tracker restarted.

Restarting your tracker reboots the device but doesn't delete any data.

Charge 3 has a small hole (altimeter sensor) on the back of the device. Don’t
attempt to restart your device by inserting any items, such as paper clips, into this
hole as you can damage your Charge 3.

Erase Charge 3

If you want to give Charge 3 to another person or wish to return it, first clear your
personal data:

On Charge 3, open the Settings app >About >.

On Charge 3, open the Settings app >Clear User Data.

49

Update Charge 3

Update your tracker to get the latest feature enhancements and product updates.

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 Charge 3 and in
the Fitbit app until the update is complete. Keep your tracker and phone close to
each other during the update process.

Note: Updating Charge 3 takes several minutes and may be demanding on the
battery. We recommend plugging your tracker into the charger before starting the
update.

If you have trouble updating your tracker, see help.fitbit.com.

50

Troubleshooting

If your tracker isn't working properly, review our troubleshooting guidance below.
Visit help.fitbit.com for more information.

Heart-rate signal missing

Charge 3 continuously tracks your heart rate while you're exercising and
throughout the day. Occasionally, the heart-rate sensor on your tracker may have
difficulty finding a good signal. When this happens, you see dashed lines where
your current heart rate usually appears.

If you're not getting a heart-rate signal, first make sure heart-rate tracking is turned
on in the settings app on your device. Next, make sure you're wearing your tracker
correctly, either by moving it higher or lower on your wrist or by tightening or
loosening the band. Charge 3 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.

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.

51

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

Other issues

If your tracker experiences any of the following problems, restart it:

l Won't sync
l Won't respond to taps, swipes, or button press
l Won't track steps or other data

For instructions on how to restart your tracker, see "Restart Charge 3" on page49.

For additional troubleshooting or to contact Customer Support, see help.fitbit.com.
