Getting started
Welcome to Fitbit Aria 2, the Wireless Smart Scale that uses advanced technology to
measure weight, body fat percentage, and body mass index (BMI) to help you take
control of your fitness.
Intended use
The Aria 2 Wireless Smart Scale is a body analyzer that measures body weight and
uses bioelectrical impedance analysis (BIA) technology to estimate body fat
percentage in generally healthy individuals 13 years of age or older. It is intended for
home use only.
What’s included
Your Fitbit Aria 2 Scale box includes:
● Fitbit Aria 2 Wireless Smart Scale
● 3 AA batteries, already installed
● Aria 2 Quick Start Guide
What’s in this document
We get you started creating a Fitbit® account and making sure your scale can
transfer the data it collects to your dashboard. The dashboard is where you may set
weight goals, analyze historical data, identify trends, log food and water, keep up
with friends, and much more. As soon as you’re done setting up your scale, you’re
ready to begin your weigh-ins. To find more information, tips, and troubleshooting,
please browse our comprehensive articles at help.fitbit.com.
Power on your scale
Your Aria 2 scale is shipped with 3 AA batteries that have been previously installed.
Pull the small plastic tab sticking out of the battery compartment to remove the tab
and power on your scale.

Setting up your Fitbit Aria 2
For the best experience, we recommend pairing your scale to the free Fitbit app,
available on iOS, Android, and Windows 10 mobile devices, as well as Bluetoothenabled Windows 10 computers.
Your Fitbit account asks for information such as height, weight, and gender to make
various calculations such as basal metabolic rate to estimate calorie burn. Your name
is visible to Fitbit friends by default. You have the option to share your age, height, or
weight with Fitbit friends, but the information you provide is private by default.
Please contact Fitbit Customer Support if assistance is needed in setting up, using, or
maintaining the Aria 2 Smart Scale or to report unexpected operations or events.
Networking Requirements
Aria 2 connects directly to your home’s Wi-Fi network and supports the following
network configurations:
Wireless 802.11b/g/n, 2.4 GHz standard
WEP / WPA / WPA2 personal security
Automatic (DHCP) IP setup (static IP configuration not supported)
Aria 2 requires an 802.11b/g/n-compatible network to connect and sync your scale
data to your Fitbit account.
Installing the Fitbit app
The Fitbit app is compatible with more than 200 devices that support iOS, Android,
and Windows 10 operating systems.
To get started, install the app and pair your scale with your mobile device:
1. Make sure the Fitbit app is compatible with your mobile device by checking
http://www.fitbit.com/devices.
2. Find the Fitbit app in one of these locations, depending on your device:
● The Apple® App Store® for iOS devices such as an iPhone® or iPad®.
● The Google Play™ Store for Android devices such as the Samsung®
Galaxy® S6 and Motorola Droid Turbo 2.
● The Microsoft® Windows Store for Windows 10 devices such as the
Lumia™ phone, Surface™ tablet, or a Bluetooth-enabled computer.
3. Install the app. Note that if you don’t have an account with the store you’ll be
required to create one before you can download the app.
4. When the app is installed, open it and tap Join Fitbit to be guided through a
series of questions that help you create your Fitbit account, or login to your
existing account.

5. Continue following the onscreen instructions to connect, or
pair
, your Aria 2 to
your mobile device. Pairing makes sure the scale and mobile device can
communicate with one another (transfer data back and forth).
Next, connect your scale to your Wi-Fi network:
1. Follow the onscreen instructions to select your preferred Wi-Fi network from
the list of available options. By connecting Aria 2 to your Wi-Fi network, your
scale will automatically and privately transfer, or
sync
, your stats wirelessly to
your Fitbit account after each use to help you track your progress.
2. Enter your Wi-Fi network password and Aria 2 will attempt to connect
automatically.
NOTE: You can enter your Wi-Fi network information manually by choosing the
Other option when selecting a network.
When you’re done connecting to the Wi-Fi network, choose a personalized icon
that will appear on your Aria 2’s screen after each use and read through the guide
about your new scale.
Verifying your scale setup
Now that you’ve linked your scale to your Fitbit account, you’ll want to verify that
the scale appears under your devices. Follow these steps to confirm your setup:
1. Login to the Fitbit app on your mobile device.
2. Tap the Account icon ( ).
3. Look for Aria 2 listed under your devices.
Changing your Wi-Fi network
If you’ve changed the name, password, router, or provider of your Wi-Fi network,
you’ll need to reconnect your Aria 2 to the updated network using the setup method
above.
For step-by-step instructions, see help.fitbit.com.

Using Your Aria 2
Your Fitbit Aria 2 scale measures your weight, body fat percentage, and BMI. When
connected your Fitbit account, measurements from your scale will automatically and
privately sync to your dashboard.
Completing a weigh-in
Follow these steps to complete a weigh-in on your Aria 2:
1. Place the scale on a flat, hard surface.
2. Remove your socks and shoes and then step onto the scale while barefoot.
Aria 2 will display your weight and body fat measurement.
3. Step off the scale. Aria 2 will automatically send your stats to your dashboard.
If you see an error message on your scale, see help.fitbit.com.
Viewing your data
After you’ve weighed yourself and your Aria 2 has synced, you can view your data in
your dashboard. The dashboard is where you’ll track progress, view your stats
including lean mass on a graph, and manually enter or delete a weight.
For more information, see help.fitbit.com.
Inviting other users to use the scale
Up to eight users can sync their Fitbit accounts with a single Aria 2 scale. If someone
who does not have an account linked with the scale steps on the scale, only their
weight will display (body fat percentage and BMI won’t appear). Registered users will
see this weigh-in attributed to “Guest”.

For step-by-step instructions, see help.fitbit.com.
Reassigning a measurement
If two users on the same scale are close in weight or body composition, your Aria 2
will prompt you to select the correct user noted by their personalized icon. If an
incorrect user is chosen, or if a weight is improperly attributed, you can reassign it to
the correct user in the Fitbit app or on the fitbit.com website.
For step-by-step instructions, see help.fitbit.com.
If your scale consistently recognizes you as a guest, see help.fitbit.com.
Choosing Regular or Lean modes
“Lean” mode is intended for professional or very high-level athletes like marathon
runners or body builders. Individuals with exceptionally low body fat relative to their
muscle mass may want to consider lean mode to improve the scale’s accuracy;
however, many very fit and active people still get more accurate readings in
“Regular” mode, which is appropriate for most users.
For step-by-step instructions, help.fitbit.com.
Ensuring accuracy
Use these tips to get the most accurate and consistent readings from your scale:
● Use your Aria 2 while barefoot. The scale cannot measure body fat percentage
if you’re wearing shoes or socks.
● Make sure your feet are dry before weighing yourself.
● Place your Aria 2 on a hard, flat surface during use. Using the scale on a soft
surface - like carpet or linoleum - may affect the accuracy of the Aria 2's
readings.
● Balance your weight evenly between both feet while standing on the scale.
● Weigh yourself at the same time each day to see consistent trends. Your
weight and body fat percentage will naturally vary over the course of the day.
● If your Aria 2 is picked up and moved between measurements, or stored
sideways against a wall when not in use, the scale will go through a calibration
process the next time it is used for weighing. Up to two consecutive weigh-ins
will then be required before your scale is recalibrated and again displays
consistently accurate measurements.
NOTE: Body fat percentage, BMI, and lean mass measurements require that your Aria
2 scale has been set up with your Fitbit account. You do not need to
complete this setup to weigh yourself.
