Charge series
On Fitbit Charge 3 and Fitbit Charge 4, you can restart your tracker from your wrist. Open the
Settings app and tap About > Reboot Device.
If your Charge series tracker is unresponsive: .
1. Plug the charging cable into the USB port on your computer or any 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.

cable. You’ll know the connection is secure when the tracker vibrates and you see a
battery icon on your tracker’s display.
4. Press and hold the button to restart your tracker:

the Fitbit logo and the tracker vibrates, the tracker restarted.

restarted.
5. Disconnect your tracker from the charging cable.
