Fitbit Charge 4 User Manual
1. CHARGE AND TURN ON FITBIT.

Charging

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.

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 4. The pins on the charging clip must lock securely with the gold contacts on the back of the tracker. Charge 4 vibrates, and a battery icon appears on the screen.

Turn on the device by gently tapping the left side of the device.

4. GO TO 'USER PROFILE' (TOP LEFT-HAND CORNER).
5. CLICK ON 'SET UP A DEVICE'.
Follow the on-screen instructions to connect (“pair”) the Fitbit device to your phone (or study iPhone). The instruction video on the right may also be useful.
Once completed, the Fitbit device will be linked to the Fitbit account. For participants using their own iPhone, the Fitbit should automatically connect upon logging into their account in the Fitbit app.

TIP: Keep track of which device is linked to which account/login by labeling the device and keeping a linkage log.

If linking multiple devices to accounts at once, it can be easy to mix up. It is helpful to label the device number in multiple spots along the side of the device using a black permanent marker. Then, track the device number with the account information (login and password) to which it has been linked.
