in the Apple App Store®or Google Play Store.
Note: Due to app updates and improvements, the VeSync app may be slightly different
than shown in the manual. In case of any differences, follow the in-app instructions.
Note: For Android™ users, you may need to select Allow to use VeSync.
Note: You must create your own VeSync account to use third-party services and
products. With a VeSync account, you can also allow your family and friends to use
your smart tness scale.
2. Open the VeSync app. If you already have an account, tap
Log In. To create a new account, tap Sign Up.
Note: You can change the name and icon at any time in the smart tness
scale settings.
3. Make sure to enable Bluetooth®permission of the APP and turn
on Bluetooth®. For Android users, please allow the app to access
nearby devices in your phone settings.

If you are a new user, you will need to enter physical information
before weighing yourself for the rst time so the scale can calculate
your body metrics. Follow the in-app instructions to create a user
prole.
Users can create or log in to their own VeSync accounts and pair the
smart scale to their separate accounts. Each user’s weight data will
be private and can be synced to their third-party apps.
Users who create or log in to a VeSync account can create multiple
user proles within their account. All users can log in to the same
account (on their own smartphones) without requiring the other
users to log out.
Note:
• Entering inaccurate information will make the scale’s measurements less
accurate.
• If you don’t identify with the available gender options, or are unsure, pick the
option that you think best physically matches you. This choice is used for
physical measurements, such as body fat percentages.
• Children under 3 years of age cannot measure body metrics other than weight.
• Minors will need a guardian’s consent to create a VeSync account.

Multiple Users
Multiple Users with Separate VeSync Accounts
Multiple Users with a Shared VeSync Account
Note: Users sharing a VeSync account will be able to view each other’s
data recorded under this account. Only the main user’s data can be synced
to third-party apps.

Using the Smart Scale
1. Place the scale on a hard, at surface.
Note:
• Placing on soft surfaces such as a shaggy carpet may cause
inaccurate measurements or tipping. If necessary, the scale can be
used on low-pile carpet with a ber length of 0.4 inches / 10 mm or
less.
2. Step on the scale, then step off. Wait for the LED screen to
display “ ” before using.
3. Place dry, bare feet on the scale’s conductive areas. While
you stand on the scale, you will see a “ ” moving across the
screen, which is measuring body impedance values to calculate
body composition. Please stay on the scale during this part until
the screen re-displays your weight. If your scale is connected to
the VeSync app, additional results (such as BMI, body fat, etc.)
will be shown in the app.
Note:
• Turning on Zero-Current Mode in the VeSync app will turn off the
scale’s electrical current and will only provide measurements for weight
and BMI. This mode can be helpful for users who are pregnant or who
have implanted medical devices, such as pacemakers.
• To measure your baby or pet, turn on Baby Mode and follow the in-
app instructions for weighing. Baby Mode will not measure other body
metrics and will only measure weight and BMI.

Troubleshooting
The scale doesn’t turn on.
• Check if the batteries are properly installed. If using the scale for
the rst time, remove the plastic insulator strip from the battery
compartment.
Information ashes on the display and then disappears.
• The batteries are low and may need to be replaced.
The smart scale can’t be added to the VeSync app.
1. Please conrm the following things before pairing:
• Allow VeSync to access Bluetooth®in your phone settings.
• The scale is not currently connected to any other phone or app.
• The scale should only be connected to your phone via the VeSync
App. Please do not connect it in your phone’s Bluetooth®settings.
• Turn off VPN (please ignore it if you are not using it).
• For Android users, please allow the app to access nearby devices in
your phone settings.
2. Try the following steps to pair your scale and your phone:
• Enable Bluetooth®on your Phone.
• Light up the scale and keep it on.
Note: If your phone system is lower than Android™ 12.0+, please authorize the
location (GPS) permission of the VeSync app.

Note: Make sure to choose the right device model (you can nd it on the back
of the scale), or it will lead to a connection failure.
• Open the Vesync App, and click “ Add Device ” or “ + ” on the top
right corner of the home page. Choose “Health” to select your device
model, and then follow the APP guides.
The scale readings seem unstable or inaccurate.
• Make sure the scale is on a hard, at surface.
• Reset the scale to zero (see page 15).
My scale will only measure my weight, not my other metrics.
• Set up your smart scale in the VeSync app. Your weight will show on
the scale display, and your weight, and more results will show on the
app.
• If you’re wearing shoes or socks, the scale cannot measure health
metrics such as body fat. Step on the scale with bare feet. [Figure 3.1]
• Make sure to place your feet on the scale’s conductive areas.
[Figure 3.2]
• Make sure Bluetooth®is turned on.
• Check if Zero-Current Mode is on. If it is, the smart tness scale will
provide measurements for only weight and BMI, not other metrics.
• If your feet are too dry or too wet, the biometrics may not be detected.
Since skin can become very dry during winter, please also try to
apply some lotion or have a foot soak when it cannot measure other
measurement values.

Note: If the scale has errors on the display, will not turn off automatically, or has a
problem not listed here, try removing the batteries for 3 seconds, then replacing
them. If the problem is not resolved, replace the batteries with new ones.
If you still need help, please contact Customer Support (see page 28).
