Safety precautions
•
Persons with implanted medical equipment, such as a pacemaker, should not
use the TBF-604. This Body Fat Monitor/Scale passes a very safe, low electrical
signal through the body during measurement, which may interfere with the
operation of a pacemaker.
• The TANITA Body Fat Monitor/Scale TBF-604 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 professional use.
• Do not use this unit on slippery surfaces such as tile flooring or wet floors.
• Disabled people should be assisted by someone else, or use a handrail
when using the TBF-604.
NOTE: Measurements will vary with the amount of moisture in the body, and can be
affected by dehydration caused by such factors as alcohol consumption, menstruation, illness, strenuous exercise, etc.
Important notes for users
The TBF-604 is intended for use by male and female adults who are only moderately
active or sedentary.
The TBF-604 is not intended for use by persons involved in intense aerobic exercise of at
least 10 hours per week and who have a resting heart rate of less than 60 beats per minute.
It is also not intended for professional athletes or bodybuilders who may experience
physical changes due to dehydration.
Body fat percentage measurements may be slightly lower or higher for the following
categories of people:
• Adults seventy years old or older
• Pregnant women
• Persons undergoing dialysis
• Persons suffering from edema
Body fat percentage measurements 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.
Recommendations for exercise programs or diets based on measured 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 TBF-604 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.

Thank you for your selection of the TANITA
Body Fat Monitor/Scale TBF-604. This personal
model uses the BIA (Bioelectrical Impedance
Analysis) technique, a state-of-the-art technology
for body fat measurement.
NOTE: Read this Instruction Manual carefully and
keep it handy for future reference.

Body Fat %
Daily fluctuations in body fat percentage based
on the BIA method
The Tanita Body Fat Monitor/Scale TBF-604 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 BIA method
The TBF-604 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.
Advantages of the Tanita TBF-604
Previously, body fat percentage was determined by measuring the thickness of subcutaneous fat by pinching it with calipers, or by laying a person on a scanning bed and passing a current from hand to foot. However, these methods had problems; measurement
values varied, professional skills were required, and extensive time was required for
measurement. Currently, the standard methods of fat percentage measurement are
DEXA (dual energy x-ray absorptiometry) and Hydrodensitometry (underwater weighing).
Based on data from both the DEXA and underwater weighing methods, Tanita established
a formula for estimating the percentage of body fat. There is a high correlation between
measurements taken with the TBF-604 and those obtained through DEXA and underwater weighing.
