1. Download Starfit APP and complete registration.
2. Click on 'Account' and find 'My Devices'.
3. Click on the '+' in the upper right corner, then click on the 'Bluetooth' logo on the page to search for smart devices.
4. When you find 'Runstar-RX' (Bluetooth name of scale), click to complete the connection.
At this point, a connected logo will appear on the screen of the scale.

Please make sure you have successfully connected the scale in the starfit APP, not in the Bluetooth list of your phone. Confirm that there are no other devices around that are connected to the body fat scale. If there are, please disconnect them first and give priority to connecting your device to the scale.

On the back of the scale, where the battery compartment is, you can see a transparent isolation tab. For rechargeable scales such as the FG2001ULB and FG2015ULB are type C charging models and do not require pulling out the isolation sheet. This description is for Runstar’s other battery-powered body fat scales.

L0 is low battery, please charge or replace batteries. ※Measurement cannot be performed while charging, and the charging cable needs to be unplugged before use.

There are 2 ways: (1) Multiple Users with Separate Starfit Accounts. Please note only 1 Starfit account can pair with the smart scale at a time when measuring. (2) Multiple Users with a Shared Starfit Account. Users who create or log in to a Starfit account can create multiple user profiles within their account.

You can find 'Code:xxx-xxx-xxx' on a lable at the back of the scale, that's the warranty code.

If you want to sync your data to Samsung Health, please turn on the 'Health Connect' switch in the Starfit app.

But please note: When measuring, you need to first open the Starfit app to ensure that the measurement data is generated before syncing to Samsung Health.

In addition, only the data of the main user can be synchronized to Samsung Health. Please make sure that you are using the main user when measuring.

Sorry, Starfit APP does not support iPad at the moment and cannot be used on iPad, so we do not recommend using iPad to download Starfit and connect with scale. Thank you!

We offer lifetime warranty for all of our device, so if your Scale is damaged within that period, send us a photo and we'll be sending you a replacement right away.
