What’s in the box

Your Charge 3 box includes:

• Tracker with a small band (color and material vary)
• Charging cable
• Additional large band (color and material vary)

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

Set up Charge 3

For the best experience, use the Fitbit app for iPhones and iPads or Android phones. You can also set up Charge 3 on 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 calls, texts, calendars, and smartphone app notifications. To create a Fitbit account, you’re prompted to enter your birthdate, height, weight, and sex to calculate your stride length and to estimate distance, basal metabolic rate, and calorie burn. After you set up your account, your first name, last initial, and profile picture are visible to all other Fitbit users. You have the option to share other information, but most of the information you provide to create an account 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 Charge 3:

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. Clip the other end of the charging cable to the port on the back of Charge 3. The pins on the charging clip must lock securely with the gold contacts on the back of the tracker. Charge 3 vibrates, and a battery icon appears on the screen.
3. 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.

Each time you open the Fitbit app, Charge 3 syncs automatically when it’s nearby. You can also use the Sync Now option in the app at any time.

Wear Charge 3

Place Charge 3 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 3 a finger’s width above your wrist bone.

For optimized heart-rate tracking while exercising:

• 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 heart-rate signal if the tracker is lower on your wrist.
• Wear your tracker on top of your wrist, and make sure the back of the device is in contact with your skin.
• 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).

Handedness

For greater accuracy, you must specify whether you wear Charge 3 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 3 on your dominant hand, change the Wrist setting in the Fitbit app From the Today tab > Wrist > Dominant in the Fitbit app, tap your profile picture > Charge 3 tile.
