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.

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.
Factory reset
Factory reset clears all user data from the scale including stored weights and Wi-Fi
networks. To factory reset your scale, complete these steps:
