Safety Precaution Bioelectric Impedance Analysis devices pass an extremely weak electrical signal through the body when taking a measurement. This weak electrical signal is not felt and is safe for individuals.
As a precaution, persons with cardiac pacemakers, electrocardiographs and/or other medical devices implanted in the body or used for life support, should not use Bioelectric Impedance Devices directly. Please wear slippers to weigh yourself, the scale will transmit an extremely weak electrical current when measuring body statistics, and it could affect the other device.
Pregnant women: Please wear slippers to weigh yourself if you are pregnant. Due to your special physical status, the scale will only show the weight.
Athletes and fitness coaches: Athletes have different body types. Scales with only foot electrodes underestimate body fat in people with lots of body fat and overestimate it in leaner people.
Under 18 years old: Only weight is available for young people under 18, because they are growing too fast and their body data is changing too frequently.
