When you use scale at first time, place the scale on the flat ground after battery installation before LCD finishing display(approx 10 seconds). Or it would make some deviations.

When electrifying at first time, LCD will show 0.0kg after full screen displaying.

Open your Android phone and start Bluetooth, then, Android When you stand on scale steady, scale will measure automatically. Please maintain your body balance and do not move. Weight numerical value will be locked after flicker for 3 times. And this numerical value is your current weight and your weight will be sent out to your phone or IPAD via Bluetooth module.

The Scale can be used continuously. When your last weight is locked, you can re-weight or let the other person weighing. But your actual BMI would be different with BMI in Android phone. Because the height of each one (or other factors) is different.
