1. Precautions for use
Don't use it like this.
1. Do not use implantable medical devices such as artificial heartbeats (Pacemakers) or life-
support medical devices such as patient monitoring devices. During InBody examination, the
instrument (heart pacemaker) may malfunction due to the flowing micro current, which may
interfere with your life. INBODY Co., Ltd. shall not be liable for any damage to any human or
device caused by failure to comply with the above precautions for use.
2. The H30NWi is a sensitive device that accurately measures body composition. Therefore,
when inspecting InBody near nearby electronics such as refrigerators, fluorescent lamps, TVs,
etc., the measurement value may be error due to the influence of electromagnetic noise, so
keep your distance from the electronics and inspect InBody.
3. If you have any contaminated or infectious diseases, do not contact or use this product. After
use, the instrument must be cleaned with a soft cloth and sterilizing agents such as ethyl alcohol.
Do not pour liquid into the product when using sterilizers. Electrical shock may occur due to

Be careful not to pull the cable too much.
Pulling the handle too hard can cause the cable to stretch, leading to product failure. The
extended cable will be restored over time, but please use it in the correct way.
Please keep it like this.
➊Slowly insert the cable from the left side of the locker.
➋Put the handle on the organized cable.
* Release the handle while standing may lead to product failure.

3. Preparing for Exam
A. Precautions for Examination
Please follow the precautions below to obtain accurate measurements by removing the factors
that affect the measurement.
➊Measure on an empty stomach before meals.
Food in the stomach affects your weight and is considered a body component, which can
cause measurement errors.
➋Measure it in the morning if possible.
The longer you stand, the more body moisture tends to flock to your lower body, and this
phenomenon is noticeable as you go into the afternoon.
➌Measure it after you go to the bathroom.
Urine and feces affect weight, but they are not body components and can cause
measurement errors.
➍Measure before exercising.
This is because even light exercise temporarily changes the body's composition.
➎Measure before taking a shower or sauna, lower-body bath, sedentary bath or bath.
This is because body water changes temporarily due to increased blood flow speed and sweat
emission.
➏Stand for about 5 minutes before measuring. If you lie down or sit down for a long time and
then stand up and measure, the moisture moves to the lower body and you measure a little
bit. It can have an impact.
B. Installing the InBody
The InBody app allows you to record and manage InBody test results.

B. Understanding the resulting items
Body fat and muscles change when you exercise or control your diet for weight management.
Therefore, when a weight control program is implemented, InBody tests can continuously
monitor body fat and muscle changes and ensure that body components are changing correctly.
ㆍWeight : The weight of the whole body, that is, the sum of the body's components.
ㆍBody fat rate: The ratio of body fat to body weight may differ even if the weight is the same.
Therefore, the body fat rate calculated by body composition analysis is an essential factor in
determining obesity. The standard range is 10 to 20 percent for men and 18 to 28 percent for
women. Children under the age of 18 have different standard body fat rates depending on
gender and height.

ㆍMuscle volume : Skeletal muscle mass attached to the bone is usually divided into cardiac
muscle, smooth muscle, and skeletal muscle, and the muscle mass shown in InBody Dial is
Skeleton Muscle Mass. Skeletal muscle mass is one of the muscles in the body that can be
changed through exercise, and the muscle mass of the arms and legs is mainly skeletal muscle.
Muscles are smaller in volume compared to the same amount of body fat, so even if they have
the same weight, their body shape depends on whether they occupy a high proportion or body
fat. That's why even if you weigh the same weight, you look stronger and slimmer if you have
a lot of muscles. The secret to a healthy and slim body is muscle mass.
ㆍVisceral fat : Fat accumulated between the intestines of the abdomen is divided into visceral
fat, subcutaneous fat, and muscle fat depending on the location of the distribution, representing
the visceral fat of the abdomen at levels 1 to 20. If your visceral fat level is 10 or higher, you
need to take care of it because it is visceral fat type abdominal obesity.
ㆍBody water volume : Most of the moisture in our body is contained in fat-free tissues, so
there is a large difference in body water from person to person. In other words, the amount of
moisture present in the body varies depending on age, composition of tissue, and gender, but
the younger the age, the higher the moisture content in the body and decreases with age, and
the gender is more men than women. In addition, moisture is contained in all tissues of the
body, but there is a difference in moisture content in each cell and tissue. Blood has about 90
percent moisture, bones about 10 percent, teeth about 5 percent, and adipose tissue between
25 and 35 percent. Compared to that, muscle tissue is 72% water. Therefore, as the fat tissue
increases in the body, the moisture content in the body decreases proportionally. Athletes with
little fat tissue contain about 70% of their body weight, while obese people with a lot of body
fat contain about 50% of their body weight.

6. Diagnosing and resolving problems
A. Check Error Messages
InBody displays an error message on the LCD screen if an abnormality occurs during use so
that the user can take the necessary action. The following are typical error messages and
actions.
➊Hand and foot fell off the electrode during measurement
Message displayed when inspection conditions are not met. Do not wear socks or stockings,
check the contact status between the hand electrode and the electric pole, and measure again.
*The palms and soles of the feet may not be measured if they are very dry or have a lot of
dead skin cells. In this case, wipe your hands and feet with a wet tissue and measure them well.
➋In Error message due to internal failure of InBody Dial
If you receive an error message below, please contact 1899-5841.

6. Diagnosing and resolving problems
B. Simple troubleshooting
Here are some of the problems you might encounter while using your product: If you can't
solve the problem after checking the contents below, please contact the customer service
center.
Question 1. The in-body test is not available and the phrase 'Please check your
thumb and heel' appears.
Answer 1. Wipe your hands and feet lightly with a wet tissue and examine them. If your palms
and soles are dry or your feet have a lot of dead skin cells, the examination may not be
smooth.
Answer 2. Take care of your posture and examine it again. Postures where armpits are attached
or both hands and arms touch other parts of the body affect the examination. Please take
a proper posture and hold the handle at the level of the power supply.
Answer 3. Change the test location. Electromagnetic interference can occur in places where
electronic and Bluetooth equipment are concentrated or where fluorescent lights are
located right above.
Question 2. The power doesn't turn on even if you press the dial button.
Answer 1. Please check the electrode direction of the battery. Battery has incorrect electrode
orientation to prevent power from turning on
Answer 2. Please change the battery. The product may be discharged.
Question 2. Weighing is not available and the loading bar continues to rotate.
Answer 1. Replace the battery. The measurement may not be smooth due to low battery.
Answer 2. Please check if there is nothing pressed on top or bottom of the product.
Measurement may operate abnormally if the product is pressed or the supporter on the
back (floor) of the product is pressed by foreign substances.
Question 3. Weight is strange.
Answer 1. Press the edge of the product to see if the product is level. Weighing on carpets or
mats can cause weight problems. Please measure the product on a hard and horizontal floor.
Answer 2. Check the four supporters on the back (floor) of the product for foreign substances
or breakage. Dirt or broken between supporters affects weight values.
Answer 3. Please check if there is nothing pressed on top or bottom of the product.
Measurement may operate abnormally if the product is pressed or the supporter on the
back (floor) of the product is pressed by foreign substances.

C. Frequently Asked Questions
I've collected the questions you frequently ask.
If you have any questions after checking the contents below, please contact our customer
service center..
Question 1. The results of the in-body test are weird. There is a slight
difference when measuring.
Answer. Differences occur if the hands and feet fall off the electrode or if the posture is not
correct during measurement. in a precise positionMeasurement must be undertaken, and
the correct posture must be maintained until the measurement is complete. If you have dry
hands and feet, wipe your hands and feet with a wet tissue and measure them. Also, the
body composition changes little by little during the day, so it is recommended to measure
it at the same time and in the same exact measurement position as possible.
Ex) After going to the bathroom before breakfast, wear light clothes and straighten your arms
and legs.
Q2. How accurate is H30NWi?
Answer: InBody Dial's weight error range is ±100g under 100kg and ±200g under 150kg.
. InBody Dial's body component accuracy is described by its correlation with DEXA* and
standard error. Correlation refers to the correlation between the dexas of the same person
and the InBody test results. A correlation of 1 means the same as a dexa; InBody Dial has
a correlation of 0.93. Next, the standard error refers to the error between InBody Dial and
the dexa measurement data. Based on body fat rate, the margin of error is 3.3%.
* Dual Energy X-ray Absorptiometry (DEXA): Standard equipment for high accuracy body
composition analysis
Question 3. What is the normal range of visceral fat levels?
Answer. The visceral fat level is Inbody's unique way of expressing the visceral fat cross
section from 1 to 20.
For adults, the lower the visceral fat level, the better if the visceral fat level is less than 10.
Question 4. What is the standard range of body fat rates?
