Once you download Fitbit Connect, right click the icon, and select "Open Main Menu." Choose "Set Up a New Fitbit Device." This takes you to a screen that allows you to either log in to an existing Fitbit account or create a new account.
If you are new to Fitbit, enter your information to create a new account. If you already have an account with a different Fitbit device connected to it, you will need to replace that device with your new Fitbit Flex, as only one device can connect to an account. If you don't want to replace the old device, set up a new account for your Flex. The program asks you for details that help calculate your calorie burn.

When you click "Next," the program connects to the Flex, which is indicated by flashing lights. Tap the Flex twice to make the device vibrate. This means the device is finished connecting.Learn more about Watches
