INDICATIONS FOR USE
The OHS Body Fat Analyzer measures weight and uses bio-electrical impedance analysis
(BIA) technology to estimate body fat, total body water percentage, bone mass, and muscle
mass in generally healthy children 10-17 years old and healthy adults.
It is intended for use in a domestic setting only.
Tips
To ensure the accuracy of measurement, please follow below instructions when
you start measurement.
Place the scale on a flat, hard surface. Soft surface such as carpet will affect the
performance of the scale.
Step onto the platform with bare feet. Stand still and keep full contact with the electrodes
until the measurement is complete.
Start measurement at least two hours after Getting up or Dining.
Avoid measurement immediately after strenuous exercise, sauna or bath, drinking, and
dining.
Always start measurement in the same time slot and on the same scale located on the
same flat, hard surface.
For maximum accuracy and repeatability, it is recommended that you should use the
device in the same time of the day and on the same location.
The condition of the skin on the bottom of your feet can affect the reading. The natural
effects of aging or activity can make this skin hard. Take the reading with clean, slightly
damp feet for best accuracy. If you are having a problem with operating this scale,
please contact customer service.
Body fat percentage estimates will vary with the amount of water in the body, and can
be affected by dehydration or over-hydration due to such factors as alcohol consumption,
menstruation, illness, intense exercise, etc.

General Instructions
OHS Body Fat Analyzer VITALIZE applies BIA (Bio-impedance Analysis) technology. A
small amount of weak current flows through the human body to detect the bio-impedance
and estimate body fat, body water, muscle mass and bone mass. The electrical current is
small and may not be felt.
This BIA technology is inexpensive, safe, non-invasive, toxic-free and harmless.
It also possesses the characteristics of simple operation and abundant information.
The current mentioned above is less than 0.5mA. However, please be aware that anyone
with a wearable or implantable medical electronic instrument, such as a pacemaker, must
avoid using this device.
The intended use of this device is for healthy children 10-17 years old and healthy adults.

Daily Measurement
With original SENSE ON patent technology, VITALIZE will switch on as you step on
the platform barefooted.
Stand still and keep full contact with the scale until the LED stops displaying
moving “o”.
Backlight Indicator
The indicator backlight will light with different color when the measuring results are
shown on the LED.
Compared with the last record of the same user ID, when the current weight is
increased over 0.5kg, the red backlight lights; when it is reduced over 0.5kg, the green
backlight lights; when it is the same (in the range of +/-0.5kg), the blue backlight lights.
Note: when it is the first measurement for a User ID, the system default backlight is blue.
After the weight is locked, the system will automatically identify the possible User ID
with most similar history records.
If it identifies one user, it will skip the step about user selection, then display the Body Fat,
Total Body Water, Muscle Mass and Bone Mass data sequentially three times and turn off.
If it identifies two or more users, for example, P1, P2 and P3, The LCD will display these
users alternately twice. you may press key to choose the left User ID or press key to
choose the right User ID. The measuring results will then be sorted into the User ID you
selected and displayed sequentially three times. If you don’t choose the user, it will display
the weight again and turn off after a few seconds.
Data Transmission
Once the Body Fat Analyzer VITALIZE is successfully
paired-up with your smartphone, please open
the “Medm Health” App and turn on your Bluetooth.
Keep smartphone and scale in transmission distance.
Step on the scale and take a measurement. Once the
measurement is finished the data is automatically
transferred to the app.
ONLY when the measuring results are attached to a
specific User ID will it be transmitted to your mobile
after measurement.
The symbol will disappear after successful data
transmission, and you may check your personal
health data stored in your smartphone.
If the data transmission fails, the symbol will
remain. The pending measurement datawill be
temporarily kept in the scale and transmitted to your
smartphone when next measurement is complete.
If it fails to identify the possible User ID, the LED will only display the weight data.
(To find out the solutions, please refer to Troubleshooting for more details.)
When your scale is successfully paired with your smartphone and the Bluetooth is ON,
VITALIZE will process data transmission instead.

Health Tips - About Body Fat
Fat is essential for human body. It can not only store energy and protect viscera, but also
regulate body temperature and maintain normal physiological function of human body.
However, too much body fat is harmful to human body and may be accompanied by Fatty
Liver, diabetes, coronary heart disease, etc.
Therefore, self-measuring and self-monitoring body fat level are beneficial to your health.
Since we can’t judge body fat level simply by our weight, this body fat analyzer VITALIZE,
with BIA (Bio-impedance Analysis) technology applied, is an accurate device that offers a
quick and comfortable way to obtain your body fat level.

a
Field strengthsfrom fixed transmitters, such as base stations for radio (cellular /
cordless) telephones and land mobile radios, amateur radio, AM and FM radio broad-
cast and TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measuredfield strength in the location in which
the device is used exceeds the applicable RF compliance level above, the device
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
[V1] V/m.

Recommended separation distances
between portable and mobile RF communications equipment and the device.
The device is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the device
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
device as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80MHz and 800MHz, the separation distance for the higher frequency
range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation
isaffected by absorption and reflection from structures, objects and people.
