This scale works on the principle of Bioelectrical Impedance Analysis (BIA). This involves a quick calculation
of body content using a harmless electric current that is not even noticeable.
When measurement of the electrical resistance (impedance) is considered alongside other data (age, height,
gender, and activity level), body fat percentage and other variables in the body can be calculated. Muscle
tissue and water conduct electricity well and therefore have a lower resistance. In contrast, bones and fat
tissue have low conductivity due to very high levels of resistance.
Calculated values only approximate the actual values for your body. Only a doctor can precisely establish
body fat, body water, muscle percentage, and bone structure using medical methods.
Tips:
• If possible, always weigh yourself at the same time every day (ideally in the morning), after having used
the restroom, on an empty stomach and with as little clothing as possible, in order to obtain comparable,
consistent results.
• Body fat percentage can only be calculated when you are bare foot; the soles of the feet may be lightly
dampened where appropriate. Results may be unsatisfactory if the soles of the feet are completely dry or
have rough patches, as this results in low conductivity.
• Stand up straight and still while weighing.
• Wait a few hours after significant physical exertion.
• Wait about 15 minutes after waking so that your body’s water content can normalize.
• Remember that only long-term trends are important. Brief deviations in weight within a few days are nor-
mally caused by loss of fluids; however, body water plays an important role in terms of well-being.
Limitations
When calculating body fat and additional values, varying and unexpected results may occur in:
• Children under 10 years of age
• Performance athletes and bodybuilders
• Pregnant women
• Persons with a fever, persons undergoing dialysis, persons demonstrating edema symptoms, and per-
sons suffering from osteoporosis
• Persons taking cardiovascular medicine (affecting the heart and vascular system)
• Persons taking vasodilating or vasoconstricting medication
• Persons with significant anatomical deviations in their legs compared with their overall
body height (leg length significantly shorter or longer).

Battery Handling Safety Precautions
• Use only the size and type of batteries specified.
• Be sure to follow the correct polarity when installing the batteries. Reversed batteries may cause damage
to the device.
• Do not mix different types of batteries together (e.g. Alkaline and Carbon-zinc or rechargeable batteries)
or old batteries with fresh ones. Always replace batteries as a simultaneous set.
• If the batteries in the device are depleted or the device will not be used for a long period of time, remove
the batteries to prevent damage or injury from possible battery leakage.
