3. Operating Instructions
3.1 Taking a Measurement
To obtain accurate body analysis readings, ensure your feet are bare and clean. The scale uses Bio-electrical Impedance Analysis (BIA) which sends a small, safe electrical signal through your body to estimate body composition. This signal cannot pass through clothing or socks.
- Place the scale on a hard, flat surface.
- Open the 'WW Scales by Conair' app on your smartphone and ensure Bluetooth is enabled.
- Gently tap the center of the scale with your foot to activate it. The display will show '0.0'.
- Step onto the scale with bare feet, positioning them on the metal electrodes. Stand still until your weight is displayed and then the body analysis measurements are complete.
- Your measurements will automatically sync to the app.

- BMI (Body Mass Index): A measure that uses your height and weight to work out if your weight is healthy.

Important Safety Note: Do not use this scale if you have a pacemaker or other internal medical device.
