Fat is essential for human body. It can not only store energy and protect viscera, but also
regulate body temperature and maintain normal physiological function of human body.
However, too much body fat is harmful to human body. It is always accompanied by Fatty
Liver, diabetes, coronary heart disease, etc.
Therefore self-measuring and self-monitoring body fat level are beneficial to your health.
Since we can’t judge body fat level simply by our weight, this body fat analyzer
BF-1256-B1, with BIA (Bio-impedance Analysis) technology applied, is an accurate device
that offers a quick and comfortable way to obtain your body fat level.

The device must emit electromagnetic
energy in order to perform its intended
function. Nearby electronic equipment may be
affected.
1. MEDICAL ELECTRICAL EQUIPMENT needs special precautions regarding EMC and
needs to be installed and put into service according to the EMC information provided in
the ACCOMPANYING DOCUMENTS.
2. Wireless communications equipment such as wireless home network devices, mobile
phones, cordless telephones and their base stations, walkie-talkies can affect this
equipment and should be kept at least a distance d = 3,3 m away from the equipment.
(Note. As indicated in Table 6 of IEC 60601-1-2:2007 for ME EQUIPMENT, a typical cell
phone with a maximum output power of 2 W yields d = 3,3 m at an IMMUNITY LEVEL of
3 V/m)
