• The scales must not be used by persons with medical implants (e.g. heart pacemak- ers). Otherwise their function could be impaired.
• Do not use during pregnancy. • Caution! Do not stand on the scale with wet feet and do not step on the scale when its surface is wet – danger of slipping!• Keep children away from packing materials (danger of suocation). Notes on handling batteries

• If your skin or eyes come into contact with battery fluid, flush out the aected areas with water and seek medical assistance.
• Choking hazard! Small children may swallow and choke on batteries. Store the batteries out of the reach of small children.
• Observe the plus (+) and minus (-) polarity signs.

• If a battery has leaked, put on protective gloves and clean the battery compartment with a dry cloth.

• Protect the batteries from excessive heat.

• Risk of explosion! Never throw batteries into a fire.

• Do not charge or short-circuit batteries.

• If the device is not to be used for a long period, take the batteries out of the battery compartment.

• Use identical or equivalent battery types only.

• Always replace all batteries at the same time.

• Do not use rechargeable batteries.

• Do not disassemble, split or crush the batteries.

• Not intended for medical or commercial use.

• Please note that measuring tolerances are possible due to technical reasons because the scale has not been calibrated.

Ages 10 ... 100 years and height settings from 80 ... 220 cm (2’7” – 7’2”) can be preset. Load capacity: max. 200 kg (441 lb, 31 St). Result in steps of 100 g (0.2 lb, 1 lb). Measurements of body fat, body water and muscle density in steps of 0.1%.

Calorie requirement is indicated in steps of 1 kcal. The BMI value (body mass index) is shown in incre- ments of 0.1.

When supplied to the customer, the scale is set to weigh and measure in “kg” and “cm”. You can switch to “pounds” (lb) and “stones” (st:lb) by switching on the scale and immediately pressing the “down” button until the desired unit is shown on the display.

Place the scale on a firm level floor; a firm floor covering is required for correct measurement.

The scale should be cleaned occasionally with a damp cloth. Do not use abrasive detergents and never immerse the scale in water.

Protect the scale against hard knocks, moisture, dust, chemicals, major temperature fluctuations and heat sources which are too close (stove, heating radiators).

Repairs may only be carried out by Beurer customer service or authorized dealers. Before submitting any complaint, first check the batteries and replace them if necessary.

3. Information on the diagnostic scale

The measuring principle of the diagnostic scale This scale operates according to the B.I.A. principle (bioelectric impedance analysis). This enables physi- cal relationships to be measured within seconds by means of an undetectable, completely harmless elec- tric current. The body fat percentage and other physical relationships in the body can be determined by measuring the electrical resistance (impedance), and the inclusion in a calculation of constants and indi

vidual parameters (age, height, gender, degree of activity). Muscle tissue and water have good electrical conductivity, and therefore lower resistance. Bones and fatty tissue, on the other hand, have low conductivity, as fat cells and bones conduct hardly any current as a result of their very high resistance. Please be aware that values obtained from the diagnostic scale represent only an approximation of actual analytical medical data. Only a specialist physician can accurately determine body fat, body water, muscle percentage and bone structure using medical procedures (e.g. computed tomography). The BMI is calculated using the height value entered and the measured weight value. General tips – If possible, always weigh yourself at the same time of day (preferably in the morning), after using the toi- let, on an empty stomach and unclothed, in order to achieve comparable results. – Important for the measurement: body fat can only be measured when barefoot and with the soles of the feet slightly moist. Completely dry soles can result in unsatisfactory measurements due to inadequate conductivity. – Stand still during the measurement. – Wait a few hours after unaccustomed strenuous activity. – Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute. Limitations When measuring body fat and other values, deviating and implausible results may occur in: – children under approx. 10 years,11 – competitive athletes and body builders, – pregnant women, – persons with fever, undergoing dialysis treatment or with symptoms of edema or osteoporosis, – persons taking cardiovascular medication, – persons taking vascular dilating or vascular constricting medication, – persons with considerable anatomic deviations of the legs in relation to total body size (length of the legs considerably shortened or lengthened).

If present, pull the battery insulating strip off the battery compartment cover or remove the battery’s pro- tective film and insert the battery according to the polarity. If the scale fails to operate, remove the battery completely and insert it again. Your scale is equipped with a “replace battery” indicator. When the scale is operated with a battery which is too weak, “L0” appears in the display field and the scale automatically switches off. The battery must be replaced in this case (4 x 1.5 V battery AAA).

5.1 Weight measurement

Step onto the scale. Stand still with your weight distributed equally on both feet. The scale begins to take measurements straight away. After flashing twice, the weight is established. If you step off the weighing area, the scale switches off after a few seconds.

5.2 Setting user data

To measure your body fat percentage and other physical data, you must enter your personal user para- meters. The scale includes over 10 memory spaces on which you and other members of your family can save per

sonal settings. Switch on the scale (tap the weighing area). Wait until the display shows “0.0”. Then press “SET”. The first memory position will appear flashing on the display. Now you can enter the fol

lowing settings: Memory position 1 to 10 Sex male , female Degree of activity 1 to 5 Body size 80 to 220 cm (2’7” – 7’2”) Age 10 to 100 years You can enter the relevant settings with short or long pressure on the “up” button or “down” button . Confirm the settings in each case by pressing “SET”. Then the scale is ready for measuring. If you do not carry out a measurement, the scale switches off auto- matically after several seconds. Degree of activity Selection of the degree of activity must refer to the medium and long term. Degree of activity Physical activity

Low: A small amount of light physical eort (e.g. short walks, light garden work, gymnastic exercises).

Medium: Physical eort for 30 minutes at least 2 to 4 times a week.

High: Physical eort for 30 minutes at least 4 to 6 times a week.

Very high: Intensive physical eort, intensive training or hard physical work for at least one hour daily.12

5.3 Taking measurements

After all parameters have been entered, you can now measure your weight, body fat and the other data.

Select the memory space where you would like to save your basic personal data by pressing the “up” or “down” button several times. These are then displayed briefly until “0.0” appears.

Step onto the scale with bare feet and make sure that you are standing still on the electrodes.

All values determined appear after weighing. Note: There may be no contact between feet, legs, calves and thighs. Otherwise the measurement will not be performed correctly. The following data are automatically displayed consecutively: 1 Body fat 2 Muscle content 3 BMI 4 Weight 5 Body water 6 Bone mass 7 Calorie consumption The scale switches itself off automatically after approx. 15 seconds.

6. Evaluation of results

Body mass index (BMI) The body mass index (BMI) is a number that is often called upon to evaluate body weight. The figure is calculated from body weight and height. The formula is: body mass index = body weight : height². The measurement unit for BMI is [kg/m²]. According to the BMI, weight is classified for adults (20 years and over) using the following values: Category BMI Underweight Severely underweight < 16 Underweight 16-16.9 Slightly underweight 17-18.4 Normal weight 18.5-25 Overweight Overweight 25.1-29.9 Obese (overweight) Class I obesity 30-34.9 Class II obesity 35-39.9 Class III obesity ≥ 40 Note that with very muscular physiques (body builders), the BMI interpretation will show overweight. The reason for this is that no account is taken of well above average muscle mass in the BMI formula. Body fat percentage The following body fat percentages are for guidance (contact your physician for further information). Man Woman

70 -100 <18 % 18 - 23 % 23,1- 28 % >28,1 % Age very good good average poor 10-14 <16 % 16 - 21 % 21,1- 26 % >26,1 % 15-19 <17 % 17- 22 % 22,1- 27 % >27,1 % 20-29 <18 % 18 - 23 % 23,1- 28 % >28,1 % 30-39 <19 % 19 - 24 % 24,1- 29 % >29,1 % 40-49 <20 % 20 - 25 % 25,1- 30 % >30,1 % 50-59 <21 % 21- 26 % 26,1- 31 % >31,1 % 60-69 <22 % 22 - 27 % 27,1- 32 % >32,1 % 70-100 <23 % 23 - 28 % 28,1- 33 % >33,1 %13 A lower value is often found in athletes. Depending on the type of sports, training intensity and physical con- stitution, values may result which are below the recommended values stated. It should, however, be noted that there could be a danger to health in the case of extremely low values. Body water The body water percentage is normally within the following ranges: Man Woman Body fat contains relatively little water. Therefore persons with a high body fat percentage have body wa

ter percentages below the recommended values. With endurance athletes, however, the recommended values could be exceeded due to low fat percentages and high muscle percentage. Body water measurement with this scale is not suitable for drawing medical conclusions, for example con

cerning age-related water retention. If necessary ask your physician. Basically, a high body water percentage should be the aim. Muscle percentage The muscle percentage is normally within the following ranges: Man Woman Bone mass Like the rest of our body, our bones are subject to the natural development, degeneration and ageing pro- cesses. Bone mass increases rapidly in childhood and reaches its maximum between 30 and 40 years of age. Bone mass reduces slightly with increasing age. You can reduce this degeneration somewhat with healthy nutrition (particularly calcium and vitamin D) and regular exercise. With appropriate muscle building, you can also strengthen your bone structure. Note that this scale will not show you the calcium content of your bones, but will measure the weight of all bone constituents (organic substances, inorganic substances and water). IMPORTANT: Please do not confuse bone mass with bone density. Bone density can be determined only by means of a medical examination (e.g. computer tomography, ultrasound). It is therefore not possible to draw conclu

sions concerning changes to the bones and bone hardness (e.g. osteoporosis) using this scale. Little influence can be exerted on bone mass, but it will vary slightly within the influencing factors (weight, height, age, gender). AMR The active metabolic rate (AMR) is the amount of energy required daily by the body in its active state. The energy consumption of a human being rises with increasing physical activity and is measured on the diagnostic scale in relation to the degree of activity entered (1– 5). To maintain your existing weight, the amount of energy used must be reintroduced into the body in the form of food and drink. If less energy is introduced than is used over a longer period of time, your body will obtain the difference largely from the amount of fat stored and your weight will reduce. If, on the other hand, over a longer period of time more energy is introduced than the total active metabolic rate (AMR) Age poor good very good 10 -100 <50 % 50 - 65 % >65 % Age poor good very good 10-100 <45 % 45 - 60 % >60 % Age low normal high 10 -14 <44% 44 - 57 % >57 % 15 -19 <43% 43 - 56 % >56 %

70 -100 <37% 37- 46 % >46 % Age low normal high 10-14 <36% 36 - 43 % >43 % 15-19 <35% 35 - 41 % >41 % 20-29 <34% 34 - 39 % >39 % 30-39 <33% 33 - 38 % >38 % 40-49 <31% 31- 36 % >36 % 50-59 <29% 29 - 34 % >34 % 60-69 <28% 28 - 33 % >33 % 70-100 <27% 27- 32 % >32 %14 calculated, your body will be unable to burn off the excess energy, and the excess will be stored in the body as fat and your weight will increase. Results in relation to time Note that it is only the long-term trend which counts. Short period fluctuations in weight over a few days are mostly the result of a loss of fluid. The interpretation of the results will depend on changes in your: overall weight and body fat, body water and muscle percentages, as well as on the period during which these changes take place. Rapid chang

es within days must be distinguished from medium term changes (over weeks) and long term changes (months). A basic rule is that short term changes in weight almost exclusively represent changes in water content, whereas medium and long term changes may also involve the fat and muscle percentages.

If your weight reduces over the short term, but your body fat percentage increases or remains the same, you have merely lost water – e.g. after a training session, sauna session or a diet restricted only to rapid weight loss.

If your weight increases over the medium term and the body fat percentage falls or stays the same, then you could have built up valuable muscle mass. If your weight and body fat percentage fall simultaneously then your diet is working – you are losing fat mass. Ideally you should support your diet with physical activity, fitness or power training. By this means, you can increase your muscle percentage over the medium term.

7. Incorrect measurement

If the scale detects an error during weighing, “ ” or “ ” appears in the display. If you step onto the scale before “0.0” appears in the display, the scale will not operate properly. Possible causes of error: – The maximum load-bearing capacity of 200 kg (441 lb, 31 St) was exceeded. Remedy: – Only weigh the maximum permissible weight. – The electrical resistance between the electrodes and the soles of your feed is too high (e.g. with heavily callused skin). – Repeat weighing barefoot. Slightly moisten the soles of your feet if necessary. Remove the calluses on the soles of your feet if necessary. – Your body fat lies outside the measurable range (less than 3% or greater than 55%). – Repeat weighing barefoot. – Slightly moisten the soles of your feet if necessary. – Your percentage of water lies outside the measur

able range (less than 25% or greater than 75%) – Repeat weighing barefoot. – Slightly moisten the soles of your feet if necessary.
