2. Setup

3. Operating Instructions
The Withings WS-50 Smart Body Analyzer is designed for ease of use. Follow these guidelines for accurate measurements.
- Taking a Measurement: Step onto the scale barefoot and stand still. The display will show your weight, and then cycle through other measurements such as body fat percentage, heart rate, and air quality data.
- User Recognition: The scale automatically identifies the user based on their weight. If multiple users have similar weights, the scale may prompt you to select your profile in the app.
- Data Synchronization: After each measurement, the data is automatically synchronized to your Health Mate app via Wi-Fi, provided the scale is connected to your network.
- Display Information: The scale's display provides real-time feedback during measurements and can also show local weather forecasts when connected to Wi-Fi.

- User Not Recognized: If the scale displays a question mark or incorrect user, manually assign the measurement to your profile in the Health Mate app. Ensure your weight is significantly different from other users for automatic recognition.
