Frequently Asked Questions - 4780 90000 Eta

How do I set up my Eta 4780 90000 scale?

Insert 3 AAA batteries with correct polarity, place the scale on a flat, hard surface, then step on to activate. Use the ▲ and ▼ buttons to set the weight unit (kg, lb, or st:lb).

How do I measure body fat?

Step barefoot onto the scale with clean, dry feet. Stand still. The scale will first display your weight, then show 'o o o o' during analysis. After a few seconds, it will display body fat, muscle, bone, water, and other readings.

What do the error messages 'Lo', 'OL', and 'Err2' mean?

'Lo' means low battery (replace all batteries). 'OL' means overload (weight exceeds 180 kg). 'Err2' means body fat percentage is out of range (< 3% or > 50%). Turn off and on or remove/reinsert batteries to reset.

Can I use this scale if I have a pacemaker or other implanted medical device?

No. Do not use the fat analysis feature if you have a pacemaker, electrocardiograph, or other implanted medical device. The bioelectrical impedance analysis may interfere with these devices.

How do I switch between weight units?

When the scale is on and displaying 0.0, press the ▲ or ▼ button to cycle through kg, lb, and st:lb. The chosen unit will be saved for future weighings.

How do I store my personal data (height, age, etc.)?

Press the □ button to enter setup mode. Use ▲ or ▼ to select a memory slot (P0-P9), then set gender, height, and age using the buttons. Press □ to confirm each step. Data is saved automatically.

Why might my measurement be inaccurate?

Inaccurate readings can result from: weighing on carpet or uneven surfaces, wet or sweaty feet, moving during measurement, not weighing at the same time of day, recent exercise, eating, or drinking. Always weigh barefoot on a hard, flat surface.

How do I clean the scale?

Use a soft, slightly damp cloth to wipe the surface. Never immerse the scale in water or use harsh chemicals. Avoid getting moisture inside the device.

What is the maximum weight the scale can measure?

The maximum weight capacity is 180 kg (396 lb or 28 st). Exceeding this will show 'OL' and may damage the scale.

How do I replace the batteries?

Open the battery cover on the bottom of the scale. Remove old batteries and insert 3 new AAA batteries with correct polarity. Close the cover. Use only alkaline batteries, and do not mix old and new batteries.

II. GENERAL INFORMATION

Why is knowledge of your weight important?

Overweight or underweight is an important indicator of your health. Overweight can increase the risk of some forms of cancer, heart diseases, diabetes, stroke, high blood pressure, arthritis, gall bladder disorders, apnoea and other diseases. Underweight brings with it risks, such as reduced immune system, osteoporosis, females can suffer from amenorrhea which causes infertility etc.

Obese people who want to lose weight and very thin people who want to gain weight should consult the treatment method and the diet with their attending physician.

For fat analysis it is essential:

• to wait approx. 15 minutes after getting up from bed because water in our body can be spread out.
  – rest for a few hours (approx. 6-8) after an unusual exhausting activity.

The fat analysis will not provide useful information to children below 10 and adults over 80 years of age, persons with fever; after undergoing dialysis; persons with osteoporosis syndromes or persons who use cardiovascular medicaments; pregnant women; athletes who have a lot of musculature; because their results may be distorted. Obese people who want to lose weight and very thin people who want to gain weight should consult their diet with their doctor.

Why is it important to know what the value of fat and water in your organism is?

Obesity (excessive amount of body fat) is a known risk for people's health that is closely connected with serious diseases such as high blood-pressure, heart diseases, diabetes, osteoarthritis and some forms of cancer. There are other, less frequent symptoms, which may be caused by obesity, such as temporary suspension of breathing during sleep and tiredness during the day. An analysis of percentage ratio of body fat or your body composition is an effective way of assessing the level of your health. The contents of water in organism is a sign of good health. If the weight is not changing and the TBW % value (total contents of water in organism) is increasing, it means that the musculature in body is increasing (which is good for health).

If the TBW % value is decreasing, it means decreasing of musculature and increasing of fat or it may indicate improper distribution of water in organism or some potential diseases relating to lack of water in the organism. In general, the more musculature, the higher the content of water in body.

BMI

The technology used in these scales, Bio-electrical Impedance Analysis (BIA) is more technologically advanced than the order Body Mass Index (BMI) method where fat % is calculated using only height and weight. BIA technology uses 5 parameters to get a more accurate resolution for the analysis (weight and biological resistance which are automatically measured by the scales together with the three personal parameters entered manually - sex, height and age). This index sets mutual ratio between the body weight and height. It can be used to determine whether the person suffers from underweight, overweight or obesity or whether his/her health condition is normal. Also with regards to heart and vascular diseases, body mass index is a relatively good risk index, particularly in healthy people. However, the index is for reference only. Experts recommend supplementing the calculation by at least measuring the waist, which makes determining disposition of the body fat more precise. BMI will not provide very reliable information for small children, elderly people and active sportsmen who have a lot of muscle mass as their results can be biased.

Minimum energy consumption KCAL

It represents minimum amount of energy consumption necessary for maintaining the basic vital functions. The data on the display show the minimum daily consumption of energy that you give out at your weight, height, age and gender.

$$ 2 3 9 \mathrm{cal} = 1 \mathrm{kJ} $$

Important notes:

1) This scale requires you to weigh yourself barefoot for the reason of correct conductivity during the body fat analysis.
2) Do not place the scale on an uneven surface or a surface covered with a carpet.
3) Do not use the fat analysis feature on this scale if you are using one of the following devices: pace maker, electrocardiograph and/or other medical device implanted in the body or device used as support.
4) Excessive drinking, eating, exercising, health conditions, used medicaments, women's menstruation cycle etc. influence the results of the analysis.
5) Here must not be a contact between feet, calves or thighs. Otherwise the measurement could be inaccurate.

III. PREPARATION FOR USE

Remove all the packing material and take the scale out. Remove all possible adhesion foils, stick-on labels or paper from the scale. Open the battery cover on the bottom of the scale, insert the battery with the correct polarity and close the cover in the opposite direction. Place the scale on flat, stable and dry surface. Switch on the scale by tapping on the board of the scale with your foot and check the displayed weight unit (kg). If you wish to set unit to lb or st:lb, adjust the with ▲ and ▼ buttons. Then put the scale of firm and flat surface (see par.

I. SAFETY WARNINGS) Fig. 2.

st = stone (American weight unit) 1 st = 6,356 kg

kg = kilogram 1 kg = 2.2 lb

lb = pound (British weight unit) 1 lb = 0.454 kg, 1 st = 14 lb

FT, In = feet; inches 1 FT = 30.48 cm, 1 In = 2.54 cm

IV. INSTRUCTIONS FOR USE

Your scale is fine electronic equipment. One of the things that are most difficult to weigh is human body as it is always in motion. If you want to obtain reliable results, always try to step with your feet at the same place on the scale and stand still. If possible, weigh yourself at the same time of a day (preferably in the morning) to obtain comparable results. Remember that excessive clothes can increase your weight as well as eating and drinking before weighing. Short-term weight fluctuation is generally attributed to loss of liquids.
