seca 769 Instruction manual and guarantee Nov 2006

1. Congratulations! English

In the seca 769 electronic personal scale, you have purchased a high-precision yet 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 accordance with national regulations, the seca 769 electronic personal scale is used primarily in hospitals, doctors’ surgeries and in-patient nursing facilities. Weight is determined within a few seconds.

In addition to the conventional determination of weight, the seca 769 also has a function for determining body mass index. For this purpose, height is entered on the keypad and the body mass index associated with the weight value is output. 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. The seca 769 can be moved on castors, and its low power consumption means that it can be used on a mobile basis with batteries for long periods.

Correct weighing – Press the Start key with no load on 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 page 15). – Stand on the scale and keep still. – Read the weighing result off the digital display. – If a load greater than 200 kg or 450 lbs is placed on the scale, St0P appears in the display. – To switch off the scale, press the Start key again.

Switching the weight display The weight display can be switched between kilogrammes (kg) and pounds (lbs) or between kilogrammes (kg) and stones (sts). – Switch on the scale using the green Start key. Weight is initially displayed in the last setting selected. – To switch the weight display between kilogrammes and pounds, press the kg/ lbs/sts key. – The kg or lbs display lights up. – To switch weight display between pounds and stones, hold down the kg/lbs/sts key for approx. 2 seconds. The lbs or sts display lights up.

Automatic switch-off/economy mode The scale automatically detects whether it is being operated on batteries or whether it is connected to the mains. – Operation on batteries: automatic shut-down after 30 seconds. – With mains operation: shut-down only via keypad.

Taring weight display (TARE) The tare function is very useful, for example for determining the weight of a child, animal or other object placed on the scale in addition to yourself. Proceed as follows: – Press the Start key with no load on the scale. – First stand on the scales yourself without the additional weight and activate the Tare function by depressing and holding the HOLD/TARE key. The display is reset to zero. 0.0 appears in the display. The note “NET” appears. – Now take the additional load onto the scale. You can leave the scale to do so, in which case ---- appears. The scale determines the weight of the additional load. You can now perform as many weighing operations as you like. – Hold the key down again to deactivate the Tare function; the scale is then back in normal weighing mode and the tare value has been erased. – The tare value is likewise erased by the scale being switched off.

Store weight value (HOLD) You can also continue displaying the weight determined once the load has been removed. This makes it possible to look after a patient first, before having to note the weight. – Press the HOLD key whilst the load is on the scale. “HOLD“ appears in the digital display. The value is stored in the display until the scale switches off automatically after 3 minutes. – The HOLD function can be switched off by pressing the HOLD key again. 0.0 appears in the display if the scale has no load on it, otherwise the current weight. The “HOLD“ display vanishes.

Body Mass Index (BMI) Body Mass Index puts height and weight in relationship to one another, providing more accurate information than ideal Broca weight, for example. A tolerance range is given which is considered ideal for health. – Press the Start key with no load on 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 for operation. – Press the FUNC key. On the display, you will see the last height entered. – You can change the value in 1 cm increments using the arrow keys. – Once the correct value is set, press the FUNC key again. The BMI function is now activated. – Step on the scale and keep still. – Read off the BMI on the digital display and compare it with the categories on page 17. – To return to normal weighing mode, press the FUNC key. – To switch off the scale, press the Start key again.

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.

5. Cleaning Clean the rubber 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.

6. What do I do if… … no weight display comes on? – Is the scale switched on? – Check the batteries. – Is the plug contact on the scale properly connected?? … 0.0 does not appear before the weighing operation? – Press the Start key again – there must not be any load on the scale … ---- appears instead of 0.0 before weighing? – Press the Start key again – there must not be any load on the scale. … 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. … the display flashes? – If you have just activated the Hold or Tare function, please wait until the scale has detected a steady weight value. The display will then stop flashing. – If there has been no activation of a function beforehand, remove the load from the scale and wait until 0.0 is displayed, then weigh again. … the display E and XX.XX appear? – Switch off the scale with the Start key and start the scale again. The scale will then work normally again. If this is not the case, disconnect the power supply by briefly removing the batteries. If this measure is equally unsuccessful, inform the Service department.
