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 Dinning.
Avoid measurement immediately after strenuous exercise, sauna or bath, drinking, and
dinning.
Always start measurement in the same time slot and on the same scale located on the
same flat, hard surface.
INDICATIONS FOR USE
The Cooey 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 the domestic setting only.
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.
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.
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 on operating this scale please
contact customer service.
The warning signs and symbols are essential to ensure your correct and safe use of
this product and protect you and others from injury. Please kindly find the meanings of the
warning signs and symbols, which you may encounter in the label and user manual, as
follows:

Cooey Body Fat Analyzer WBT1-357-B applies BIA (Bio-impedance Analysis)
technology. A small amount of weak current flows through the human body so as 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 cheap, 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 an 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.

the scale to measure your current weight. For only weight reading.
1. Position the scale on a flat, hard surface. Carpeted or uneven floors may
affect accuracy.
2. Step onto the scale platform and remain still while the scale computes your weight.
3. The scale will display your weight value.
4. The scale will automatically turn off after a few seconds.
1. Press the platform centre and remove your foot.
2. “0.0” will be displayed.
3. The scale will switch off and is now ready for use.
This initialisation process must be repeated if the scale is moved.

Health Tips - About Body Fat
Human body is made up of, amongst other things, a percentage of fat. Body fat is vital
for a healthy, functioning body, protects vital organs, helps regulate body temperature,
stores vitamins and helps the body sustain itself when food is scarce. However, too much
body fat or indeed too little body fat will damage to your health. It is difficult to gauge how
much body fat we have in our bodies simply by looking at ourselves in the mirror.
This is why it is important to measure and monitor your body fat percentage. Body fat
percentage gives you a better measure of fitness than weight alone–the composition of
your weight loss could mean you are losing muscle mass rather than fat-you could still
have a high percentage of fat even when a scale indicates‘normal weight’.

Health Tips - About Body Water
Body water is the single most important component of body weight. It represents over
half of your total weight and almost two thirds of your lean body mass (predominantly
muscle). Water performs a number of important roles in the body:
All the cells in the body, whether in the skin, glands, muscles, brain or anywhere else,
can only function properly if they have enough water. Water also plays a vital part in
regulating the body’s temperature balance, particularly through perspiration.
The combination of your weight and fat measurement could appear to be ‘normal’ but
your body hydration level could be insufficient for healthy living.
Health Tips - About Muscle Mass
According to the American College of Sports Medicine (ACSM), lean muscle mass may
decrease by nearly 50 percent between the age of 20 and 90. If you do nothing with it
you’re losing muscle and increasing fat. It is also important to know your muscle mass %
during weight reduction. At rest, the body burns approximately 110 additional calories for
each kilo of muscle gained. Benifits of gaining muscle mass include:
• Reversing the decline in strength, bone density and muscle mass with aging
• Maintenance of flexible joints
• Guide weight reduction when combined with a healthy diet.
Health Tips - About Bone Mass
Regular exercise and a balanced diet can help maintain healthy bones. Like muscle,
bone is a living tissue that can respond to exercise by becoming stronger. For most
people, bone mass peaks in their thirties. Then people begin to lose bone. Regular
exercise can help prevent that loss.
Calcium and vitamin D, good sources of which are dairy products, green leafy
vegetables and fish, contribute to healthy bones.
The bone mass readings given by this product are anestimation of the amount of bone in
your body. Those with osteoporosis or low bone densities may not get accurate
estimations. If you have any concern regarding your bones please consult your doctor
timely.

EMC Guidance
1. MEDICAL ELECTRICAL EQUIPMENT needs special precautions regarding EMC and
needs to be installed and put into service according to the EMC information provided in
the ACCOMPANYING DOCUMENTS.
2. Wireless communications equipment such as wireless home network devices, mobile
phones, cordless telephones and their base stations, walkie-talkies can affect this
equipment and should be kept at least a distance d = 3,3 m away from the equipment.
(Note. As indicated in Table 6 of IEC 60601-1-2:2007 for ME EQUIPMENT, a typical cell
phone with a maximum output power of 2 W yields d = 3,3 m at an IMMUNITY LEVEL of
3 V/m)
