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 smartphone or tablet, you can also use a
Bluetooth-enabled Windows 10 PC. Keep in mind that a phone is required for call, text, and calendar notifications.
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 your tracker
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.
8
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 you see a battery icon on the screen.
4. 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.

Day Sync.
) > Charge 3 tile > All-
You can also use the Sync Now option in the app at any time.
To learn more about syncing your device, see help.fitbit.com
.
11
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 14
.
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, keep these tips in mind: 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.
12
l l l
Make sure the tracker is in contact with your skin.
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.
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 (about 10 seconds). You should see a heart-rate reading.
13
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
Remove a wristband
To remove the wristband:
1. Turn Charge 3 over 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 button on the strap.
3. Gently pull the band away from the tracker to release it.
4. Repeat on the other side.
14
Attach a new wristband
To attach a new band, press it into the end of the tracker until you feel it snap into place.
If you have trouble attaching the band or if it feels loose, gently move the band back and forth to make sure it is attached to the tracker

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.

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
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.

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'll see dashed lines where your current heart rate usually appears.
If you're not getting a heart-rate signal, first 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.
48
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 tracker: l l l
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 tracker, see
"Restart Charge 3" on page 46 .
