Initial Start-Up Initial Start-Up
Transtek Glass Body Fat Analyzer LS203-B applies BIA (Bio-impedance Analysis)
technology. A small amount of weak current flows through the human body so as to detect
the bio-impedance and estimate body fat. The electrical current is small and may not be felt.
This BIA technology is cheap, safe, non-invasive, toxic-free and harmless. It also
possesses the characteristics of simple operation and abundant information.
The current mentioned above is less than 1mA. However, please be aware that anyone
with an wearable or implantable medical electronic instrument, such as a pacemaker, must
avoid using this device.
The intended use of this device is for adult’s indoor use only.

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 LS203-B ,
with BIA (Bio-impedance Analysis) technology applied, is an accurate device that offers a
quick and comfortable way to obtain your body fat level.
