What's in the box Your Fitbit Charge 3 box includes: Tracker with small wristband (color and material vary) Charging cable Additional large band (color and material vary) 6 The detachable wristbands on Charge 3 come in a variety of colors and materials, sold separately. 7 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. 9 Set up with your Windows 10 PC If you don't have a smartphone, you can set up and sync Charge 3 with a Bluetoothenabled Windows 10 PC and the Fitbit app. To get the Fitbit app for your computer: 1.

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 "Wristband size" on page 51. 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. 15 Basics Learn how best to navigate, check the battery level, and care for your tracker.

In the Fitbit app, 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. 41 Icon Zone Calculation Description Out of Below 50% Your heart rate may be elevated, but not enough to be Zone of your considered exercise. maximum heart rate Fat Burn Between 50% and 69% of your maximum heart rate 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. Cardio Between 70% and 84% of your maximum heart rate 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. Peak This is a high-intensity exercise zone. This zone is for short intense sessions that improve performance and speed. Greater than 85% of your maximum heart rate 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. 42 For more details about heart rate tracking, including links to relevant American Heart Rate Association information, see help.fitbit.com.

If you have trouble updating your tracker, see help.fitbit.com. 47 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.
