1. SAFETY PRECAUTIONS AND
STORAGE
1.1 Important safety instructions
Please read the following instructions carefully, as they contain
important information concerning the setting up, use and care
of your new 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.
Although there are no known side effects, the body fat monitor
must NOT
• During an acute contagious disease;
• By persons with medical implants (e.g. pacemakers);
• By persons with any heart disease. Use the monitor after
• Never use it in combination with artificial heart-lung and
• Never use it in combination with an electrocardiograph and
be used under the following conditions:
consultation with your doctor;
other electronic life support systems;
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 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
1.2 Care and Storage
Clean the main unit with a soft dry cloth. If the main unit is
heavily stained, wipe it with a cloth lightly dampened with
water or detergent, then wipe it dry with a dry cloth.
Avoid an excessive amount of water, this can cause internal
damage. Do not wipe the unit with benzene, paint thinner,
alcohol, or other volatile detergents.
1.3 Features of the product
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 “underwater weighing method” and the DEXA (Dual
Energy X-ray Absorbtiometry) method, which are said to be
the standard measurements methods for measuring the 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 the Start screen is displayed.
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 and on BMI calculations are displayed alternately, as well as their interpretations.
Memory
The memory can store the personal data (height, weight, age
and gender) of up to 9 people simultaneously.

2. HOW TO OBTAIN A CORRECT
MEASUREMENT
The body fat monitor is a monitoring device. It should be used
at a fixed point in time and with a fixed period between two
measurements. For instance: once a week on a Sunday
morning. With this in mind, please find in paragraph 2.1 a
table with recommended times for measurement.
There are conditions that are not suitable for taking a body fat
measurement. There are also some exceptions that are
excluded for taking a body fat measurement. This is explained
in paragraph 2.2 and 2.3. This chapter will end with some
recom mendation (paragraph 2.4) before taking a measurement.
2.1 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. (See chart)
2.2 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
vigorous exercise
After drinking
much alcohol
Immediately after
taking bath or sauna
After taking a large amount
of water or after a meal
2.3 Exceptions
In some cases, the measured body fat percentage may differ
too much from the actual body fat percentage. These exceptions are the people for who measurements may vary due to
consistently changing amounts of water and tissue density
within their bodies.
Children of
growing stage
Patients of
osteoporosis
having very
low bone density
Patients under -
going dialysis Pregnant women
Elderly people
and women after
menopause
People with
a fever
Those having
swelling
Bodybuilders or
professional
athletes
2.4 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 display error
indication or inaccurate results.
Please pay special attention in winter because the air is dry
and/or the temperature is low.

3.4 To take a measurement
Step1: Stand with both feet slightly apart.
Step 2: Hold the grip electrodes.
Wrap your middle finger around the
groove of the handle. Place the palm of
your hand on the top and the bottom
electrodes. Put your thumbs up, resting
on top of the unit.
Step 3: Hold your arms straight out, at a
90 degree angle to your body. Do not
move during the measurement.
Step 4: Confirm the ready to measure
display.
The indicator turns on.
Step 5: Push the START button.
The display turns on.
Step 6: Immediately after having pushed
the Start button, hold the electrodes
correctly with both hands as shown on
the right. The unit automatically detects
that it is held and starts measuring.
Step 7:
During measuring, the display shown to
the right turns on and the arrows rotate
from LOW to TOO HIGH.
As soon as measurement is finished the
FAT% is displayed on the left display,
while indicating the interpretation of
this value (NORMAL >> TOO HIGH) on
the right display. After approx. 5
seconds, both displays change to BMI
(Body Mass Index).
Every 5 seconds, the displays change
from FAT% to BMI and vice-versa.
You can start another measurement
when the indicator turns on.
For an explanation how to interpret the
measurement results in detail, please
refer to chapter 4.
Step 8: Push the O/I button to turn the
power off.
If you do not push the O/I button, the
unit will turn off automatically,
approximately three minutes after
displaying the measurement results.

4. HOW TO INTERPRET MEASURED
RESULTS
4.1 BMI Value
Graphical interpretation of BMI
value (LOW >>
TOO HIGH)
BMI is an internationally used index to show the body
condition by checking the balance between the height and
the weight.
It is calculated by the following formula:
BMI = weight / height
BMI BMI value*
< 18.5 LOW
>18.5 and < 25 NORMAL
> 25 and < 30 HIGH
> 30 TOO HIGH
* The above mentioned indices refer to the values for obesity proposed
by the WHO (World Health Organization)
4.2 Body fat percentage
Displays the body fat mass as the percentage of body weight.

Important information regarding Electro Magnetic
Compatibility (EMC)
With the increased number of electronic devices such as
PC's and mobile (cellular) telephones, medical devices in
use may be susceptible to electromagnetic interference from
other devices. Electromagnetic interference may result in
incorrect operation of the medical device and create a
potentially unsafe situation. Medical devices should also not
interfere with other devices.
In order to regulate the requirements for EMC (Electro
Magnetic Compatibility) with the aim to prevent unsafe
product situations, the EN60601-1-2 standard has been
implemented. This standard defines the levels of immunity
to electromagnetic interferences as well as maximum levels
of electromagnetic emissions for medical devices.
This medical device manufactured by OMRON Healthcare
conforms to this EN60601-1-2:2001 standard for both immunity and emissions.
Nevertheless, special precautions need to be observed:
• Do not use mobile (cellular) telephones and other devices,
which generate strong electrical or electromagnetic fields,
near the medical device. This may result in incorrect operation of the unit and create a potentially unsafe situation.
Recommendation is to keep a minimum distance of 7 m.
Verify correct operation of the device in case the distance
is shorter.
Further documentation in accordance with EN60601-1-2:2001
is available at OMRON Healthcare Europe at the address
mentioned in this instruction manual. Docu mentation is also
available at www.omron-healthcare.com.
