Introduction
Thank you for selecting the Tanita Body Fat Monitor/Scale TBF-521.
This product 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
TBF-521. 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 TBF-521 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 TBF-521.
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 TBF-521 is intended for use by adults and children with moderately active to inactive
lifestyles and by adults 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.
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 TBF-521 is not intended for pregnant women, professional athletes or bodybuilders.
Recommendations for exercise programs or diets based on calculated data should be
