Safety precautions
Important safety instructions
Please read the following instructions carefully, as they contain
important information concerning the setting up, use and care of your
Body Fat Monitor.
Keep this manual for future reference.
Do not disassemble the body fat monitor. Apart from the batteries, it contains
no user serviceable parts.
Do not subject the device to strong shocks.
Do not subject the unit to extreme temperatures, humidity, dust, moisture or
direct sunlight.
Although there are no known side effects, the body fat monitor must NOT be
used under the following conditions:
•During an acute contagious disease;
•By persons with medical implants (e.g. pacemakers);
•By persons with any heart disease. Use the monitor after consultation with
your doctor;
•Never use it in combination with artificial heart-lung and other electronic
life support systems;
•Never use it in combination with an electrocardiograph and other (portable)
electronic medical devices.
Do not use the body fat monitor in a highly humid environment such as sauna or
while you are in a bath or in a shower.
Never submerse the unit in water.
Do not let unattended children or infirm persons have access to the unit.
If you discover that the body fat monitor is damaged or does not operate
properly, switch it off immediately and stop using it. An authorized dealer
using only original OMRON spare parts must carry out any repairs. Any
part of the unit may only be repaired or replaced by the Omron Service
representative.
Please note that this device is only intended to measure the body composition.
Do not commence weight reduction or exercise program without instructions/
supervision by a doctor.

About body fat measurement
What is body fat percentage?
Body fat percentage refers to the percentage of body
fat mass (the weight of the fat) in relation to body
weight. The weight that is not fat is referred to as
the fat free body mass.
The human body is made up mainly of water with
fat being the next largest percentage. The remainder
of the body consists of proteins and carbohydrates
in the form of muscles and minerals stored in
your bones.
Your body fat percentage and body fat mass are
determined by the following calculations:
Body fat percentage (%) = {Body fat mass (kg) ÷ Body weight (kg)} x 100
Body fat mass (kg) = Body weight (kg) - Fat-free mass (kg)
Ratio of the body consituents

About body fat measurement
Principles of body fat percentage measurement
Omron Body Fat Monitor measures the body fat percentage by the Bioelectrical
Impedance (BI) method.
What is Bioelectrical impedance (BI) Method?
Tissues containing much water such as muscles, blood vessels, and bones are
highly conductive with electricity, but fat tissues are not.
Therefore, by using this principle, it is possible to determine the ratio of fat
tissue compared to other tissues in the body by measuring the electric
resistance of the body tissues,using extremely weak electric current
applications to the body. As the electric current applied to the human body
during the body fat measurement is extremely weak, of about 50 KHz to
500 µA, one will not feel the electric stimulation, and this method is safe for
the human body.
The electric resistance is determined by “facilitation of electric conductivity”
and the “distance of the electricity conduction.” In order to find “facilitation of
electric conductivity” for estimating the ratio of fat, it is necessary to always keep
the “distance of the electricity conduction” at the same level.
That is why we must maintain a correct posture during the measurement.
How to measure the body fat percentage
To calculate the body fat percentage (fat information of whole body) from
the electric conductivity between both hands, the following five items
(1) electric resistance, (2) height, (3) weight, (4) age, and (5) gender and a
formula are employed.
This formula is formulated by OMRON using the basic data on human body,
obtained from several hundreds people. By referring to the accumulated
basic data, the body fat percentage is estimated from the conditions specific
to users (5 items).
This basic data is obtained by “Under-water weighing method”, which is
considered the most accurate body fat measurement method at present.

About body fat measurement
Caution to certain conditions
In some cases, the measured body fat percentage may differ too much from
the actual body fat percentage. These exceptions are people whose
measurements may vary due to continuous changing amount of water and
tissue density within their bodies.
Growing children Elderly people and Those having Patients of
women after swelling osteoporosis
menopause having very low
bone density
People with Bodybuilders or Patients under Pregnant women
a fever professional athletes going dialysis
The conditions or circumstances NOT suitable for a
correct measurement
If a measurement is made under the following physical conditions, the
measured body fat percentage may differ significantly from the actual one
because the water content in the body changes.
Immediately after Immediately after After drinking After taking a large
vigorous exercise taking bath or sauna much alcohol amount of water or
after a meal

About body fat measurement
Recommendations for taking a measurement
If the palms of your hands are dry or the temperature of your palms or the grip of
the electrodes are extremely cool, stable measurement is impossible, which may
lead to error indication display or inaccurate results.
Please pay special attention in winter because the air is dry and/or the
temperature is low.
Conditions Actions
Hands are dry. Slightly moisten hands with a wet towel,
then measure.
When you hold the grip Warm the grip electrodes by leaving the
electrodes, they feel cold. unit in a warm room for approximately
ten minutes.
Your body and hands are Warm your hands by immersing in warm
cold due to the blood not water or staying in a warm room.
circulating well. Start the measurement again.
Recommended times for measurement
Understanding the normal changes in your body fat percentage can help you
in preventing or reducing obesity.
Being aware of the times when
the body fat percentages shift
within your own daily schedule
will assist you in obtaining
an accurate trend of your body
fat. It is recommended to use
this unit in the same environment
and same daily circumstances.

Features of the product
• Measures body fat percentage and more
Measures body fat percentage, Basal Metabolic Rate (BMR),
assessment of body fat percentage & Body Mass Index (BMI) with
graphical interpretation of body type.
• Accurate measurement
The body fat percentage is measured based on the electric resistance and
the personal data such as height, weight, age and gender. The measured
results are closely correlated with the "under-water weighing method",
which is said to be the standard measurement method for measuring body
fat percentage.
• Measurement is fast and simple
After setting the data, body fat mass can be measured by simply holding
the grip electrodes and pushing the Start button.
The measured results are displayed approximately 7 seconds after
setting data.
• Large and clear displays
The easy to read large digital and graphic displays can be understood at
a glance. The measured results based on body fat percentage, BMR and on
BMI calculations are displayed, as well as their interpretations and body fat
percentage assessment.
• Memory
The memory can store the personal data (height, weight, age and gender)
of up to 9 people simultaneously.
• Small, lightweight and portable

BMI
BMI is the international indicator of whether
or not one is within a healthy weight range
for one’s height, by calculating the balance of
height and weight. It is calculated as follows:
BMI= Weight(kg) ÷ (height(m))2
BMI assessment
Lean less than 18.5
Normal more than 18.5 and less than 25
Level 1 obese more than 25 and less than 30
Level 2 obese more than 30

Why calculate body fat?
Let’s aim for a fit body by knowing your body type
When losing weight, it is important to understand where the lost weight is
coming form. In order for a diet or exercise program to be truly successful,
it must maintain or increase your lean body mass while reducing your body fat.
It’s important to monitor
your body fat percentage
and BMI value before
putting efforts in building
a healthy body carefully.
With Omron Body Fat
Monitor, you can quicky
and accurately measure
your body fat.
