INDICATIONS FOR USE The Transteks` 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. 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. 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 dehydration or over-hydration due to such factors as alcohol consumption, menstruation, illness, intense exercise, etc. 2 3 Overview Overview Device Components LCD Display LCD Display User Key(ID1) User Key(ID2) User Key(ID3) User Key(ID4) Touch Key Battery Compartment Sensor Successful analysis Pound Successful APP Connection Data pending to transmit to smartphone List 1.

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. 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 alonethe 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 indicatesnormal 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 bodys 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 youre 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. 14 15 Appendix WarningDont near active HF surgical equipment and the RF shielded room of an ME system for magnetic resonance imaging, where the intensity of EM disturbances is high.
