Place the monitor on a hard, flat surface where there is minimal vibration to ensure safe and
accurate measurement.
Do not use the monitor near other products such as microwave ovens that emit electromagnetic waves.
Doing so may cause the monitor to malfunction, preventing accurate measurements.
Avoid excessive impact or vibration to the monitor.
Doing so may damage the monitor or cause it to malfunction,or may cause setting to be erased.
Always…
To ensure accuracy, readings should be taken without clothing and under consistent conditions of hydration. Always remove your
socks or stockings, and be sure the soles of your feet are clean before stepping on the measuring platform. Be sure that the arch of
each foot is aligned with the center of the measuring platform. Don’t worry if your feet appear too large for the unit, accurate readings
can still be obtained if your toes overhang the platform. It is best to take readings at the same time of day. Try to wait about two hours
after getting up, eating, or strenuous exercise before taking measurements. While readings taken under other conditions may not have
the same absolute values, they are accurate for determining the percentage change as long as the readings are taken in a consistent
manner. To monitor your progress, compare your weight and body fat percentage readings taken under the same conditions over a
period of time.
Note: An accurate reading will not be possible if the soles of your feet are not clean, if your knees are bent or if you are sitting down.

Body Composition Guide
This Body Composition Monitor is intended for adults aged 18-99 years. Children aged 5-17 years can use the monitor for weight only:
the other features are not applicable to children.
Thanks to major investment in the latest BIA Technology and sports science research, TANITA has upgraded the Athlete Mode function
to make measurements more accurate and suitable for a wider range of users.
Who should use Athlete Mode?
Adults aged 18 years and over who either:
・Train or exercise for 12 hours or more a week and have been doing so for at least six months.
・Are body builders.
・Are professional athletes who want to monitor their progress at home.
・Have a lifetime history of fitness and who used to do more than 12 hours a week but do less now.
Pregnant women should only use the weight function.
Other functions are not intended for use when pregnant.
This Body Composition Monitor is intended for home use only. It is not intended for professional use in places such as hospitals or
medical or fitness facilities. It is not designed for such heavy usage. Using the monitor in this type of professional environment will
invalidate the warranty.
This Body Composition Monitor product provides readings for informational purposes only.
This product is not intended to diagnose or treat any disease or abnormalities. Please consult your physician if you have any questions
or concerns related to your health.
Tanita Body Composition Monitors calculate your body composition using Dual Frequency Bioelectrical Impedance Analysis (BIA).
Safe, low-level electrical signals are passed through the body via the Tanita foot pads on the monitor platform. The signal can flow
easily through fluids in muscles and other body tissue but meets resistance as it passes through body fat, because body fat only
contains a small amount of fluid. This resistance is called impedance. The impedance readings are then entered into medically
researched mathematical formulas to calculate your body composition.
The Tanita RD-953 incorporates medical grade Dual Frequency BIA technology,allowing
you to have the highest body composition accuracy in the comfort of your home.
Research has shown that using two dierent bioelectrical impedance frequencies,
provides essential data of a person's intracellular and extracelluar status. This advanced
technology allows greater accuracy when calculating body composition measurements.
When Is the Best Time To Use My Body Composition Monitor?
Your body water levels naturally fluctuate throughout the day and night. Any significant changes in body water may aect your body
composition readings. For example, the body tends to be dehydrated after a long night sleep so if you take a reading first thing in the
morning your weight will be lower and your body fat percentage higher. Eating large meals, drinking alcohol, menstruation, illness,
exercising, and bathing may also cause variations in your hydration levels.
To get the most reliable reading it is important to use your Body Composition Monitor at a consistent time of day under consistent
conditions. A good time to take measurements is before your evening meal.

What Is Body Fat Percentage?
Body fat percentage is the amount of body fat as a proportion of your body weight.
Reducing excess levels of body fat has shown to reduce the risk of certain conditions such as high blood pressure, heart disease,
diabetes and cancer. The chart below shows the healthy ranges for body fat.
Your Body Composition Monitor automatically compares your body fat percentage reading to the Healthy Body Fat Range chart.
Underfat: below the healthy body fat range. Increased risk for health problems.
Standard (-)/Standard (+): within the healthy body fat percentage range for your age/gender.
Overfat: above the healthy range. Increased risk for health problems.
Obese: high above the healthy body fat range. Greatly increased risk of obesity-related health problems.

What Is Total Body Water Percentage?
Total Body Water Percentage is the total amount of fluid in a person’s body expressed as a percentage of their total weight.
Water plays a vital role in many of the body’s processes and is found in every cell, tissue and organ. Maintaining a healthy total body
water percentage ensures the body functions eciently and reduces the risk of developing associated health problems.
Your body water levels naturally fluctuate throughout the day and night. Your body tends to be dehydrated after a long night's sleep
and there are dierences in fluid distribution between day and night. Eating large meals, drinking alcohol, menstruation, illness,
exercising and bathing may cause variations in your hydration levels.
Your body water percentage reading should be used as a guide and should not be used to specifically determine your recommended
total body water percentage. It is important to look for long-term changes in total body water percentage and maintain a consistent,
healthy total body water percentage.
Drinking a large quantity of water in one sitting will not instantly change your body water level. In fact, it will increase your body fat
reading due to the additional weight gain. Please monitor all readings over time to track relative changes.
Every individual is dierent, but as a guide the average total body water percentage ranges for a healthy adult are:
Female: 45 to 60%
Male: 50 to 65%
Source: Tanita Research
Note: The total body water percentage will tend to decrease as the percentage of body fat increases. A person with a high percentage
of body fat may fall below the average body water percentage. As you lose body fat, the total body water percentage should gradually
move towards the typical range given above.
(Applicable age 18-99)
What Is Visceral Fat Rating?
This function indicates the amount of visceral fat in your body.
Visceral fat is the fat that is in the internal abdominal cavity, surrounding the vital organs in the abdominal area. Research shows that
even if your weight and body fat remains constant, as you get older the distribution of fat changes and is more likely to shift to the
abdominal area especially post menopause. Ensuring you have healthy levels of visceral fat may reduce the risk of certain diseases
such as heart disease, high blood pressure, and the onset of type 2 diabetes.
The Tanita Body Composition Monitor provides you with a visceral fat rating from 1 – 59.
Rating 1 - 12.5
Indicates you have a healthy amount of visceral fat. Continue monitoring your rating to ensure that it stays within this healthy range.
Rating 13 - 59
Indicates you have an excess amount of visceral fat. Consider making changes in your lifestyle by changing your diet or exercising more.
Source : Data from Columbia University (New York) & Tanita Institute (Tokyo)
Note: You may have a high visceral fat level even if you have a low body fat rate.
- Consult a physician for an accurate medical diagnosis.

(Applicable age 18-99)
What Is Basal Metabolic Rate (BMR)?
Your Basal Metabolic Rate (BMR) is the minimum level of energy your body needs when at rest to function eectively. This includes the
functioning of your respiratory and circulatory organs, neural system, liver, kidneys, and other organs. You continue to burn calories
even when sleeping.
About 70% of the calories your body uses every day are used by your basal metabolism. In addition, energy is used when doing any
kind of activity. The more vigorous the activity, the more calories are burned. This is because skeletal muscle (which accounts for
approximately 40% of your body weight) acts as your metabolic engine and uses a large amount of energy. Your basal metabolism is
greatly aected by the amount of muscle you have, so increasing your muscle mass helps increase your basal metabolism.
By studying healthy individuals, scientists have found that people's metabolic rate change as they age. Basal metabolism rises as
achild grows. After peaking at the age of around 16 or 17, it typically starts to gradually decrease.
Having a higher basal metabolism increases the number of calories used and helps decrease the amount of body fat. A low basal
metabolic rate makes it harder to lose body fat and overall weight.
How Does a Tanita Body Composition Monitor Calculate BMR?
The basic method of calculating Basal Metabolic Rate (BMR) is a standard equation that uses weight and age.
Tanita has conducted in-depth clinical research into the relationship of BMR and body composition resulting in a much more accurate
and personalized reading for the user based on impedance measurements. This method has been medically validated using indirect
calorimetry (measuring breathcomposition).*
*Reliability of the equation for Basal Metabolic Rate:At 2002 Nutrition Week: Scientific and Clinical Forum and Exposition
Title: International Comparison: Resting Energy Expenditure Prediction Models:
The American Journal of Clinical Nutrition.
(Applicable age 18-99)
What Is Metabolic Age?
This function calculates your BMR and indicates the average age associated with the type of metabolism.
If your metabolic age is higher than your actual age, it is an indication that you need to improve your metabolic rate. Increased exercise
builds healthy muscle tissue, which improves your metabolic age.
The reading is shown as a number between 12 and 90. Values under 12 are displayed as “12” and over 90 are displayed as “90”.
(Applicable age 18-99)
What Is Muscle Mass?
This function indicates the weight of muscle in your body. The muscle mass displayed includes skeletal muscle, smooth muscle
(such as cardiac and digestive muscle) and the water contained in these muscles.
Muscles play an important role as they act as an engine that consumes energy. As your muscle mass increases, your energy
consumption increases helping you reduce excess body fat levels and lose weight in a healthy way.
The muscle mass is judged for persons aged 18 and over.
Muscle mass is judged by calculating the amount of muscle mass against the person’s height, and then the amount is
classified. The My Tanita app that links with this device displays the muscle mass judgement as a muscle score, as shown
below. The larger the number, the more muscle the person has.

What Is Physique Rating?
This feature assesses your physique according to the ratio of body fat and muscle mass in your body.
As you become more active and reduce the amount of body fat, your physique rating also changes accordingly. Even if your weight does
not change, your muscle mass and body fat levels may be changing to make you healthier and reduce your risk of certain diseases.Each
person should set their own goal of which physique they want to achieve, and follow a diet and fitness program to meet that goal.

What Is Muscle Quality Score?
Muscle quality score indicates the “quality (state) of muscle” which changes according to factors such as age and fitness. The
muscles of young people or those who exercise regularly is normally in a good state, but the state of muscles deteriorates in elderly
people or those who do not get enough exercise. Inner Scan Dual Body Composition Analyzer uses 2 dierent frequencies to
measure Bioelectrical Impedance, and these results are used to evaluate the muscle state using the Muscle Quality Score.
It is important to maintain a good balance
between muscle mass and quality.
More ★ indicates a better state of muscle.
(Max. ★★★★)

What Is Bone Mass?
This function indicates the amount of bone (bone mineral level, calcium or other minerals) in the body.
Research has shown that exercise and the development of muscle tissue are related to stronger, healthier bones. While it is unlikely
that there will be noticeable changes in bone structure over short periods, it is important that you develop and maintain healthy bones
by having a balanced diet and plenty of exercise. People worried about bone disease should consult their physician. People who suer
from osteoporosis or low bone density due to age (young or old), pregnancy, hormonal treatment or other causes may not get
accurate bone mass readings.
Below is the result of estimated bone masses of persons aged 20 to 40, who are said to have the largest amounts of bone mass by
weight. (Source: Tanita Body Weight Science Institute)
Please use the charts below as a guide for comparing your bone mass readings.
・Persons described below may obtain varying readings and should take the values given for reference purposes only.
- Elderly persons
- Women during or after menopause
- People receiving hormone therapy
・“Estimated bone mass” is a value estimated statistically based on its correlation with the fat-free amount (tissues other
than the fat). “Estimated bone mass” does not give a direct judgment on the hardness or strength of the bones or the risks
of bone fractures.
If you have concerns over your bones, you are recommended to consult a specialist physician.
(Applicable age 18-99)
What Is Body Mass Index (BMI)?
This function indicates the relationship between height and weight.
The World Health Organization (WHO) considers an index of 18.5 to 25 as optimal.
