When do I know the BodyGem device is calibrated?
To begin a measurement, press the amber button on top of the BodyGem device. The unit will calibrate, beep and the lighted button will begin flashing green. You are now ready to begin the measurement. The measurement needs to begin within one minute after calibration is complete. If the measurement is not started within this time, the lighted button will turn amber and you will have to push the button again.
