The patient is an intended operator. The patient can measure, and charge battery under normal
circumstances and maintain the device and its accessories according to the user manual.
INDICATIONS FOR USE
• The Body Fat Analyzer measures weight and uses bio-electrical impedance analysis (BIA) technol-
ogy to estimate body fat, total body water percentage, bone mass and muscle mass in generally
generally healthy children 10-17 years old and healthy adults.
• It is intended for use in the domestic setting only.

Tips
To ensure the accuracy of measurement, please follow below instructions when you start meas-
urement.
• Place the scale on a at, 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 meas-
urement 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 at, 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 on 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 de-
hydration or over-hydration due to such factors as alcohol consumption, menstruation, illness, intense
exercise, etc.

INITIAL START-UP
General Instructions
The Body Fat Analyzer GBF-835 applies BIA (Bio-impedance Analysis) technology.
A small amount of weak current ows 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 charac-
teristics of simple operation and abundant information.
The current mentioned above is less than 0.5mA. However, please be aware that anyone with an wear-
able 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.

APPENDIX
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 dam-
age to your health. It is difcult 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 tness 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’.
The table as follows may be used as a guide:
The body fat ratio (Unit: %) :
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 hydra-
tion level could be insufcient for healthy living.
The table as follows may be used as a guide:
The body water ratio (Unit: %) :

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 in-
creasing 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. Benits of gaining muscle
mass include:
• Reversing the decline in strength, bone density and muscle mass with aging
• Maintenance of exible joints
• Guide weight reduction when combined with a healthy diet.
The table as follows may be used as a guide:
The body muscle ratio (%):
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 sh, con-
tribute 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.
The bone range (kg)≤ 10.0kg
