Regulatory and Safety Notices

Get started
Boost your routine with Fitbit Charge 6*, the only premium fitness tracker with Google built in. With the fitness tools you need to stay motivated and crush your goals, running your day and your routine has never been easier.
Take a moment to review our complete safety information at support.google.com. Charge 6 is not intended to provide medical or scientific data.
*Fitbit Charge 6 works with most phones running Android 9.0 or newer or iOS 15 or newer and requires a Google Account, Fitbit mobile app and internet access. Some features require a Fitbit mobile app and/or a paid subscription. See fitbit.com/devices for more information.
What's in the box
Your Charge 6 box includes:

Tracker with small band (color and material varies)

Charging cable

Additional large band

The detachable bands on Charge 6 come in a variety of colors and materials, sold separately.

Charge your tracker
A fully-charged Charge 6 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 Charge 6:
1. Plug the charging cable into the USB port on your computer, a UL-certified USB wall charger, or another low-energy charging device.
2. Hold the other end of the charging cable near the port on the back of the tracker until it attaches magnetically. Make sure the pins on the charging cable align with the port on the back of your tracker.
Charging fully takes about 1-2 hours. While Charge 6 charges, double-tap the screen or press the button to turn it on and check the battery level. Swipe right on the battery screen to use Charge 6. A fully charged tracker shows a solid battery icon.
7

Wear Charge 6
Wear Charge 6 around your wrist. If you need to attach a different size band, or if you purchased another band, see the instructions in "Change the band" on page 13.
Placement for all-day wear vs. exercise
When you're not exercising, wear Charge 6 a finger's width above your wrist bone. In general, it's always important to give your wrist a break on a regular basis by removing your tracker for around an hour after extended wear. We recommend removing your tracker while you shower. Although you can shower while wearing your tracker, not doing so reduces the potential for exposure to soaps, shampoos, and conditioners, which can cause long-term damage to your tracker and may cause skin irritation.
For optimized heart-rate tracking while exercising: l During a workout, experiment with wearing your tracker a bit higher on your wrist for an improved fit. Many exercises, such as bike riding or weight lifting, cause you to bend your wrist frequently, which could interfere with the heartrate signal if the tracker is lower on your wrist.
10

l Wear your tracker on top of your wrist, and make sure the back of the device is in contact with your skin.
l Consider tightening your band before a workout and loosening it when you're done. The band should be snug but not constricting (a tight band restricts blood flow, potentially affecting the heart-rate signal).
Fasten the band
1. Place Charge 6 around your wrist. 2. Slide the bottom band through the first loop in the top band.
11

3. Tighten the band until it fits comfortably, and press the peg through one of the holes in the band.
4. Slide the loose end of the band through the second loop until it lies flat on your wrist. Make sure the band isn't too tight. Wear the band loosely enough that it can move back and forth on your wrist.

Handedness
For greater accuracy, you must specify whether you wear Charge 6 on your dominant or non-dominant hand. Your dominant hand is the one you use for writing and eating. To start, the Wrist setting is set to non-dominant. If you wear Charge 6 on your dominant hand, change the Wrist setting in the Fitbit app:

From the Today tab in the Fitbit app, tap the devices icon

Wrist

Dominant.

Charge 6

Wear and care tips
l Clean your band and wrist regularly with a soap-free cleanser. l If your tracker gets wet, remove and dry it completely after your activity. l Take your tracker off from time to time. For more information, visit the Fitbit Wear & Care page.
Change the band
Charge 6 comes with a small band attached and an additional large, bottom band in the box. Both the top and bottom bands can be swapped with accessory bands, sold separately on fitbit.com. For band measurements, see "Band size" on page 58. Fitbit Charge 5 bands are compatible with Fitbit Charge 6.
Remove a band
1. Turn over Charge 6 and find the band latches.
2. To release the latch, use your fingernail to press the flat button toward the band.
13

3. Gently pull the band away from the tracker to release it.
4. Repeat on the other side.
Attach a band
To attach a band, press it into the end of the tracker until you hear a click and it snaps into place. The band with the loops and peg attaches to the top of the tracker.

To see your daily stress management score, wear your tracker to sleep, and open the Fitbit app on your phone the next morning. From the Today tab, tap the Stress Management tile. Log how you feel throughout the day to get a clearer picture of how your mind and body respond to stress. With a Fitbit Premium subscription, see details about your score breakdown.

The number of times your tracker vibrates indicates which zone you're in:
1 buzz = fat burn zone 2 buzzes = cardio zone 3 buzzes = peak zone
l 7 minutes after you enter a heart-rate zone throughout the day (for example, during a brisk walk).

If your tracker doesn't detect a heart-rate signal, first make sure heart-rate tracking
is turned on in the Settings app on your tracker. 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 6 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.
For more information, see the related help article.

GPS signal missing

Environmental factors including tall buildings, dense forest, steep hills, and thick cloud cover can interfere with your tracker's ability to connect to GPS satellites. If your tracker is searching for a GPS signal during an exercise, you'll see

GPS connecting

GPS satellite, the tracker stops trying to connect until the next time you start a GPS exercise.
For best results, wait for Charge 6 to find the signal before you start your workout.
