Calling the 800-number on FitBit devices is not the only way to receive help with problems concerning the device. There is a help link on the FitBit website that offers virtual help with all FitBit devices.
On the help site, all FitBit devices are listed. To obtain help, choose the device from the list, and then review the list of most common and helpful articles are available. If the specific problem isn't listed, choose a category. If this still doesn't answer the question, visit the online FitBit community to chat with other FitBit users or look to see if the problem has been encountered before. Inversely, contact FitBit support through the link on the help page.
