Set up Fitbit FB415
For the best experience, use the Fitbit app for iOS, Android, or Windows 10. If you
don’t have a smartphone or tablet, you can also use a Bluetooth-enabled Windows
10 PC.
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 FB415
A fully charged FB415 has a battery life of up to 4+ days. Battery life and charge
cycles vary with use and other factors; actual results will vary.
To charge FB415:
1. Plug the charging cradle into the USB port on your computer or a UL-
certified USB wall charger.
2. The charging cradle uses a spring clip to hold FB415 in place while charging.
Pinch the spring clip and place FB415 in the charging cradle. The pins on the
charging cradle must align with the gold contacts on the back of the watch.
The connection is secure when the percent charged appears on screen.
