Setup Guide
Follow these steps to set up your Leaone BF8028-B Smart Bluetooth Body Weight Scale:
- Unpack the Scale: Carefully remove the scale from its packaging. Ensure all components, including any included batteries, are present.
- Install Batteries: Open the battery compartment on the underside of the scale. Insert the required batteries, ensuring correct polarity.
- Place the Scale: Position the scale on a hard, flat surface. Avoid carpets or uneven flooring, as this can affect measurement accuracy.
- Download the App: Scan the QR code provided in the product's instruction booklet with your smartphone to download the official Leaone health tracking application. Alternatively, search for "Leaone" in your device's app store (iOS App Store or Google Play Store).
- Create an Account: Open the app and follow the on-screen prompts to create a user account.
- Pair with Bluetooth: Enable Bluetooth on your smartphone. Step onto the scale to activate it. Within the app, navigate to the device pairing section and select your Leaone scale from the list of available Bluetooth devices. The app will guide you through the pairing process.

Operating Instructions
Using your Leaone Smart Bluetooth Body Weight Scale is straightforward:
- Taking a Measurement:
- Ensure your feet are clean and dry.
- Step onto the scale barefoot. The scale will automatically turn on and begin measuring.
- Stand still on the scale until your weight is displayed and stabilized. For body composition analysis, ensure your feet are in contact with the two highly-sensitive electrodes on the scale's surface.
- The scale will display your weight. If the app is open and connected via Bluetooth, all 12 body composition data points will sync automatically to your smartphone. If the app is not open, the weight data will be stored on the scale and sync the next time the app is connected.
- Changing Units: The scale supports units in pounds (LB), kilograms (KG), and stones (ST). You can typically change the unit setting within the Leaone app. Some models may have a physical button on the underside of the scale for this purpose.
- Multiple Users: The Leaone app allows for the creation of multiple user profiles. When different users step on the scale, the app will intelligently identify the user based on their weight history or prompt you to select the correct user.

Maintenance
Proper care ensures the longevity and accuracy of your scale:
- Cleaning: Wipe the scale's tempered glass surface with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the surface or electrodes.
- Storage: Store the scale in a cool, dry place. Avoid extreme temperatures or direct sunlight.
- Battery Replacement: When the low battery indicator appears on the display or in the app, replace all batteries with new ones of the specified type. Ensure correct polarity during installation.
- Avoid Impact: While the scale features durable tempered glass, avoid dropping it or subjecting it to heavy impact, which could cause damage.
Troubleshooting
If you encounter issues with your Leaone Smart Bluetooth Body Weight Scale, refer to the following common problems and solutions:
- Scale Does Not Turn On:
- Check if batteries are installed correctly.

- Inaccurate Readings:
- Ensure the scale is on a hard, flat, and level surface.
- Perform a recalibration by stepping on the scale briefly, then stepping off and waiting for it to display "0.0" before stepping on again for a measurement.
- Ensure your feet are clean and dry and making full contact with the electrodes for body composition analysis.
- Bluetooth Connection Issues / Data Not Syncing:
- Ensure Bluetooth is enabled on your smartphone.
- Make sure the Leaone app is open and running in the foreground or background.
- Try restarting your phone's Bluetooth or the phone itself.
- Re-pair the scale with the app if necessary (refer to Setup Guide).
