seca 808 Instruction manual and guarantee Jan 2007

1. Congratulations! English

By purchasing the seca 808 electronic personal scale, you have acquired a highly-accurate and sturdy piece of equipment. seca has been putting its experience at the service of health for over 150 years now, and as market leader in many countries of the world, is always setting new standards with its innovative developments for weighing and measuring. In addition to determining weight conventionally, the seca 808 can also calculate Body Mass Index and body composition

(proportion of body tissue made up of fat and water). For this purpose, an imperceptible, harmless AC current is passed through the body. The weight display can be switched between kilogrammes (kg), pounds (lb) and stones (st). Weight is determined within a few seconds. The scale is of a very sturdy construction and will give you long and loyal service. It is easy to operate and the large display is easy to read.

2. Safety Before using the new scale, please take a little time to read the following safety instructions. • Follow the safety instructions in the in• Do not expose the scale to excessive struction manual. moisture. • Keep the operating manual and the • Do not drop the scale or subject it to videclaration of conformity contained olent shocks. therein in a safe place. • Have repairs carried out exclusively by • You must not use this scale if you wear authorised persons. a cardiac pacemaker, an insulin pump • Use only the type of battery stated (see or other electronically-controlled medi“Changing the batteries” on page 17). cal device. Their function could be impaired.

3. Before you start… Unpacking Remove the packaging and place the scale on a firm, level surface.

Power supply The scale is powered exclusively by batteries. The LC display has a low power consumption – 8.000 weighing operations can be performed with one set of batteries. When or bAtt appear in the display, you should change the batteries. You require 4 AAA-type 1.5 V batteries. All the illustrations are on the foldout flap at the front. – Carefully turn over the scale so that the Check that the polarity is correct. base of the scale is accessible (see Fig. – Close the cover. 3). – Then turn the scale back up the right – Push the battery compartment closure way. towards “Battery” and open the cover. – Insert the new batteries in the battery compartment.

Switching the weight display The weight display can be switched between kilogrammes (kg) and pounds (lb) or between kilogrammes (kg) and stones (st) (see Fig. 2). Once you switch back on, weighing will be performed using the new unit of measurement.

4. Setting up and aligning the scale – Place the scale on a level surface. – Ensure that only the feet of the scale are in contact with the floor. The scale may not be in contact at any other point.

– If an uneven floor (e.g. thick-pile carpet) contacts the base of the scale, push on the carpet feet supplied (see Fig. 5).

5. Operation Simple Weighing – Step gently onto the scale (see Fig. 4). The vibration switch starts the scale. se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. The scale is then automatically set to zero and ready to use. – If necessary, switch the weight display (see “Switching the weight display” on page 11). – Stand on the scale and keep still. Once weight has been determined, the

scale will also try to measure body composition, which can be seen by the symbol o moving across the display. You can now simply get off the scale (the scale will briefly show an error message). – Read the weighing result off the digital display. – If a load greater than 150 kg or 330.6 lb is placed on the scale, St0P appears in the display.

Automatic switch-off/economy mode The scale switches off automatically after 20 seconds.

Weighing with measurement of BMI, body fat and body water The seca 808 can also calculate the following body data in addition to weight: Body Mass Index, body fat and body water proportion. For this purpose, an imperceptible, harmless AC electric current is passed through the body and the measured values classified by weight, gender, build and height. These data must previously have been entered in the scale (see “Storing personal data” on page 12). So that your values are determined correctly and are comparable with one another over several days, please note the following instructions: • You should perform the measurement implausible results, because body wabarefoot, otherwise there is insufficient ter is distributed differently throughout contact with the sensors (in this case the body during sleep.

Storing personal data The seca 808 can store personal data for up to four different people. In addition, it is possible to perform a measurement in so-called Guest Mode (see “Measuring in Guest Mode” on page 14). The four personal memories are each assigned to one of the four keys MENU, ▲, ▼ or SET, and can subsequently be selected using these keys when the scale is switched on. – Switch on the scale using the one of the – You can change the value in the increfour keys (MENU, ▲, ▼ or SET) to the ments shown by the graduations in the memory of which the personal data is display using arrow keys ▲ and ▼. to be assigned. – Once the correct value has been set, se(a, 8.8.8.8.8. and 0.0 appear consecbriefly press the SET key. utively in the display.

The menu for entering age appears. – You can increase or decrease the value using arrow keys ▲ and ▼. – Once the correct value has been set, briefly press the SET key. This concludes data entry for the personal data for one person.

Measuring with automatic person recognition The seca 808 can use the weight to recognise whether the person standing on the scale matches one of the stored sets of data in the four people memories. So it is not always necessary to bend down to switch on the scale using one of the keys. To do this, the measured weight is compared with the stored weights and, if it is within a certain tolerance, it is then linked to the appropriate personal memory. The current weight is then stored again and used as the basis for subsequent measurements. As a result, the scale is always updated if you lose weight continuously - while on a diet, for example. Note: When you get on the scale the first time after storing your personal data, you must first switch on the scale using the key assigned to your data. The scale can then assign your weight to your personal data. – Step gently onto the scale. The vibrastored weights.

Check whether the correct personal memory symbol is being displayed during the measurement. If necessary, switch on the scale using the MENU, ▲, ▼ or SET key assigned to your personal memory before measuring if automatic person recognition does not work.

Evaluation of body fat and body water values The body fat and body water values shown as a percentage of body weight below are guideline values from the World Health Organisation (WHO). Body fat: Women Age Underweight Healthy Zone Overweight Obese Age 20 – 40 below 21% 21 – 33% 33 – 39% above 39% Age 41 – 60 below 23% 23 – 35% 35 – 40% above 40% Age 61 – 79 below 24% 24 – 36% 36 – 42% above 42%

Underweight below 8% below 11% below 13%

Men Healthy Zone 8 – 19% 11 – 22% 13 – 25%

Overweight 19 – 25% 22 – 27% 25 – 30%

Obese above 25% above 27% above 30%

Body water Women Men Children

50 – 55% 60 – 65% 65 – 75%

Note: People with a high body fat value very often have a body water value below that of the WHO guidelines. Sportsmen and women with little body fat and high muscle mass often exhibit values above these guidelines. In infants, water makes up 75 % of body weight. This proportion then drops to 65 % by the end of the growth period and in old age is nearer 55 %. (Source: Schmidt, Thews, Physiologie des Menschen [Human physiology], 25th edition, Springer-Verlag in Berlin and Heidelberg, 1993). The measured values will only give indications of possible irregularities in the water and fat values of your body. The precision of the measurement depends on various influencing factors. If you notice deviations from the standard values, please ask your doctor for a differential diagnostic examination.

Evaluating Body Mass Index for adults: Compare the value determined with the categories quoted below which correspond to those used by WHO, 2000. • BMI below 18.5: Warning, this patient weighs too little. There could be a tendency to anorexia. An increase in weight is recommended to improve well-being and performance. If in doubt, consult a specialist. • BMI between 18.5 and 24.9: The patient is of a normal weight. He can stay as he his. • BMI between 25 and 30 (pre-obese): The patient is slightly to moderately overweight. He should cut his weight if he is already ill (e.g. diabetes, hypertension, gout, fat metabolism disorders). • BMI over 30: Weight reduction is essential. Metabolism, cardiovascular system and bones are all under strain. A consistent diet, plenty of movement and behavioural training are all recommended. If in doubt, consult a specialist.

6. Cleaning Clean the surface and the housing as required using a domestic cleaning agent or commercially-available disinfectant. Follow the manufacturer’s instructions. Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for cleaning. Such substances can damage the high-quality surfaces.

7. What do I do if… … no weight display comes on? – Is the scale switched on? – Check the batteries. … 0.0 does not appear before weighing? – Start the scale again after it switches off automatically – there must not be any load on the scale – and only its feet should be in contact with the floor. ... the message Err 2 appears when measuring body fat and body water values? – You should carry out the measurement barefoot, otherwise there is insufficient contact with the sensors. If you have very dry skin, moisten your feet slightly to improve conductivity. ... the values for body fat and body water deviate significantly from the standard values? – Stand as still as possible during measurement. – Place both feet as completely on the sensors as possible (see Fig. 6). – Have you entered your height correctly? Switch on the scale with the key assigned to your personal memory and then press one of the arrow keys ▲ and ▼. The symbol for your personal memory will flash and the entered data will be shown. Check this and amend if necessary (see “Storing personal data” on page 12). – In the following cases, measurement will give implausible results: during pregnancy or if your body contains medical implants such as artificial joints, metal plates or screws. In such cases, you should have your doctor carry out a differential diagnostic examination to obtain correct results. – People with a high body fat value very often have a below-average body water value. – Very athletic people with little body fat and high muscle mass often exhibit values above the guidelines. In this case, select the ‘Athletic’ option for your build. ... the values for body fat and body water deviate significantly between different measurements? – Wherever possible, perform measurements each day at the same time and under the same conditions, e.g. 15 minutes after getting up. – Measurements taken directly after sleeping give implausible results because body water is distributed differently throughout the body during sleep. – Measurements taken directly after strenuous physical exercise also give implausible results. Take a relatively long break before measuring. – A heavy meal or drinking alcohol also give implausible results. … one segment is illuminated constantly or not at all? – The relevant segment has a fault. Inform Servicing. … the display shows ? – Battery voltage is running low. Change the batteries in the next few days. … batt appears in the display? – Batteries are empty. Put in new batteries. … St0p appears in the display? – Maximum load has been exceeded.
