The FCC requires the user to be notified that any changes or modifications made to this device that are not expressly approved by Tanita Corporation may void the user’s authority to operate the equipment.
Introduction
Thank you for selecting the Tanita Body Fat Monitor/Scale BF-541. This family model uses the BIA (Bioelectrical Impedance Analysis) technique, a state-of-the-art technology for body fat assessment.
Safety Precautions
Persons with implanted medical equipment, such as a pacemaker, should not use the
BF-541. This Body Fat Monitor/Scale passes a low-level electrical signal through the body, which may interfere with the operation of a pacemaker.
• The Tanita Body Fat Monitor/Scale BF-541 is intended for home use only. This unit is not intended for professional use in hospitals or other medical facilities; it is not equipped with the quality standards required for heavy usage experienced under professional conditions.
• Do not use this unit on slippery surfaces such as wet floors.
• Disabled people should be assisted by someone else, or use a handrail when using the BF-541.
Note: Body fat percentage estimates will vary with the amount of moisture in the body, and can be affected by dehydration or overhydration due to such factors as alcohol consumption, menstruation, illness, intense exercise, etc.
Important Notes for Users
The BF-541 is intended for use by adults and children with moderately active to inactive lifestyles. It is not intended for people with athletic body types.
Tanita defines “athlete” as a person involved in intense physical activity of at least 10 hours per week and who has a resting heart rate of approximately 60 beats per minute or less. Tanita’s athlete definition includes “lifetime of fitness” individuals who have been fit for years but currently exercise less than 10 hours per week.
Tanita’s athlete definition does not include “enthusiastic beginners” who are making a real commitment to exercising at least 10 hours per week but whose bodies have not yet changed to require the Athlete mode.
People with athletic body types should use Tanita Body Fat Monitor/Scales equipped with Athlete mode.
Body fat percentage estimates may be slightly lower or higher for the following categories of people:
• Adults seventy years old or older
• Persons undergoing dialysis
• Persons suffering from edema
Body fat percentage estimates for these persons should not be treated as absolute values, but may be used as relative values for checking body fat percent variations over a period of time.
The BF-541 is not intended for pregnant women, professional athletes or bodybuilders. Recommendations for exercise programs or diets based on calculated data should be
determined by a doctor or licensed medical professional. Do not attempt to evaluate the data by yourself.
Recorded data may be lost if the BF-541 is used incorrectly or is exposed to electrical power surges. Tanita takes no responsibility for any kind of loss caused by the loss of recorded data.
Tanita takes no responsibility for any kind of damage or loss caused by these units, or any kind of claim made by a third person.

Principles of Estimating Body Fat Percentage
The Tanita Body Fat Monitor/Scale BF-541 allows you to estimate your body fat percentage at home as easily as you measure your weight.
What is Body Fat Percentage?
Body fat percentage is the percentage of fat in your body. Until now, your absolute weight has determined whether or not you were considered overweight or obese. In recent years, the definition of obesity has been refined to mean the presence of excess body fat. Too much body fat has been linked to conditions such as high blood pressure, heart disease, diabetes, cancer, and other disabling conditions.
The chart below shows reasonable ranges of body fat percentage.
The BIA Method
The BF-541 uses the BIA (Bioelectrical Impedance Analysis) technique. In this method, a safe low-level electrical signal is passed through the body. It is difficult for the signal to flow through fat in the human body, but easy to flow through moisture in the muscle and other body tissues. The difficulty with which a signal flows through a substance is called impedance. So the amount of fat in the body can be accurately estimated by measuring the impedance. The signal used is very low, making it safe and imperceptible.
The illustration on the left show how the signal travels through the body.
Body Fat Percentage Fluctuations in a Day
Hydration levels in the body may affect body fat readings. Readings are usually highest in the early waking hours, since the body tends to be dehydrated after a long night’s sleep. For the most accurate reading, a person should take a body fat percentage reading at a consistent time of day under consistent conditions.
Besides this basic cycle of fluctuations in the daily body fat readings, variations may be caused by hydration changes in the body due to eating, drinking, menstruation, illness, exercising, and bathing. Daily body fat readings are unique to each person, and depend upon one’s lifestyle, job and activities.
The graph on the left shows an example of daily body fat percentage fluctuations.
