All FitBit products come with a 12 month warranty against defects in materials and workmanship. Should you have any issues with your FitBit item, you can contact FitBit directly or otherwise contact FitShop for further details.
All trackers are wireless. The FitBit will sync automatically when it is in close range to the USB dongle. You must first set up your FitBit account online at http://www.fitbit.com/start and simply follow the prompts.
You may use the Tracker independently of the Fitbit website if you wish. However, syncing your data to Fitbit.com allows you to enjoy a more robust picture of your activity levels. From the website you can view your steps and distance over time, watch your weight, view your food intake versus calorie burn, see how well you are sleeping, interact with friends, earn badges for your fitness achievements and quite a bit more.
All FitBit trackers only need to be 3-5 metres away (when plugged into your computer) from the USB dongle. If there is no new data on your tracker, however, it will not sync, and you can view when your last sync was on your FitBit.com dashboard. You also need to ensure that you have created your account with FitBit.com for it to sync, it will not connect if the software is not running on the computer.
The tracker can record and hold detailed daily data for 7 days (minute by minute calorie burn and sleep data), and summarised daily data (steps, calories and distance) for 30 days.
You can access your Fitbit profile and sync from any computer as long as it has the Fitbit software installed and a USB dongle plugged into it. You can download the free Fitbit software by going to http://www.fitbit.com/start.
The tracker has a motion sensor in it that analyses your movement patterns in such a way that it can distinguish between when you are awake and when you are asleep. It works most accurately when the Tracker is worn on your wrist, as arm movements are a good indicator of how heavily you are sleeping.
You can set up your Fitbit Zip to connect and sync via your iPhone 4S, iPhone 5, or 3rd generation iPad. Android devices and the iPhone 4 and earlier models will not sync with your Zip, but if you have the Fitbit app installed, they will show information synced via your computer, and allow you to manually enter data on the go.
To set up your Zip via an iPhone 4s, iPhone 5, or 3rd generation iPad, please do the following:
The Zip uses 3V coin batteries, CR2025, which can be found wherever batteries are sold. The battery should last 4-6 months with regular use. When it is below 25% a low battery indicator will show on the display of your Zip, as well as on your Fitbit.com profile under 'Devices'. A flashing battery icon indicates that your Zip is very close to being completely out of battery life, and that it should be replaced very soon. It is also important to know that data could be lost if your Zip is not synced before replacing the battery. Use the battery door tool that comes with your Zip to open and close the battery door compartment, which is located on the back of the Zip.
The Fitbit One and the Fitbit Flex use a barometric pressure sensor that measures the weight of air to determine your elevation. It is extremely accurate and is similar to the technology used in expensive hiking watches.
