Remove all packaging and adhesive foils. Open the battery cover on the bottom, insert 3 AAA batteries with correct polarity, and close the cover. Place the scale on a flat, stable, dry surface. Tap the weighing surface to turn it on, and select your preferred weight unit (kg, lb, or st:lb) using the arrow buttons.

How do I measure body fat and other body composition metrics?

First, save your personal data (memory number, gender, height, age) by following the setup procedure. Then step onto the scale barefoot with dry feet. Stand still; the scale will automatically measure weight, body fat %, body water %, muscle mass %, bone weight, BMI, and daily kilocalorie requirement. Results cycle on the display.

What do the error codes mean?

'LO' means battery is dead. 'Err2' indicates very low or very high body fat percentage. 'Err' appears when weight exceeds the maximum 180 kg. If unusual signs appear, remove and reinsert the battery or move the scale away from electromagnetic interference.

How do I replace the batteries?

Open the battery cover on the bottom of the scale. Remove old batteries and insert 3 new AAA 1.5 V batteries with correct polarity. Close the cover. Do not mix old and new batteries or different types.

How should I clean and maintain the scale?

Clean the surface with a soft, damp cloth. Do not use harsh chemicals, abrasives, or solvents. Never immerse the scale in water. Store horizontally in a dry place away from direct sunlight and heat sources.

Who should not use the body fat analysis feature?

Do not use the body fat analysis if you have a pacemaker, electrocardiograph, or other implanted medical device. Also, avoid use during pregnancy, if you have edema, or during dialysis treatment.

Can I use the scale on a carpet?

No, the scale should be placed on a flat, hard, and stable surface. Soft or uneven surfaces like carpet can affect measurement accuracy.

Why does the scale not turn on?

Check that batteries are inserted correctly and have sufficient charge. If the display shows nothing, replace the batteries. Also ensure the scale is on a flat surface and you step firmly to activate auto step-on.

How do I switch between weight units?

Turn on the scale and wait until 0.0 appears. Press the ▲ or ▼ arrow button to cycle between kg, lb, and st:lb. The selected unit will be saved.

What is the maximum weight the scale can measure?

The maximum weight capacity is 180 kg (397 lb or 28.3 st). Do not exceed this limit to avoid damaging the scale.

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.

BMI	Underfat Healthy Overfat Obese
	< 18,5 18,5 - 27 28 - 39 > 40

Optimum energy consumption KCAL

It represents optimum amount of energy consumption necessary for maintaining the basic vital functions and balanced metabolism. The data on the display show the optimum daily consumption of energy that you give out at your weight, height, age and gender. You should also take in this amount of energy to keep your metabolism balanced. If you intend to reduce your weight, your daily energy intake should be a bit lower. However, remember to keep carbohydrates, fats and proteins balanced in your diet. 239 cal = 1 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) Tables and information concerning optimum arrangement of body characteristics is only orientational.

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 (Fig. 1). If possible, weigh yourself at the same time of the day (best in the morning) and also on the same place to get 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.

A) Regular weighing mode

Turn the scale on by stepping on the weighing surface. After a moment, the measured weight flashes and the value remains displayed for several seconds. Then the scale are switched off automatically.

B) Weighing and total body analysis mode

Setting (change) of personal data for the body fat and water analysis

Before the first analysis, it is necessary to put in personal data (sex, height and age) which will be saved to the memory. It is possible to save data of 10 persons in the scale's memory.

The input data can be set and gradually changed in the following range:

Memory Gender Height Age
0 – 9 male / female	female	80 – 220 cm2'07.5" – 7'02.5"	6 - 100

1. Turn the scale on by stepping on the weighing surface (until will show 0.0).
2. Press the ⬙ button Number of memory will start the flash on the display (e.g. 1).
3. Select the number of the memory (with button ▲or )▼ which you want to save the data for the person to be weighed.

Confirm by pressing the button.

1. Set your sex with the ▲ or ▼ button:

male / female

Confirm by pressing the button.

1. Set your height with the ▲ or button.

Confirm by pressing the button.

1. Set your age with the ▲ or button (Age)

Confirm by pressing the button.

Now all the personal data is saved (changed). Wait till 0.0 appears. Stand on the scale and wait for results.

The following data will start to show after a few seconds:

1. • Weight in set units
2. • Body fat contents in % (fat)
3. • Body water contents in % (TBW)
4. • Musculature contents in %
5. • Bone weight contents in kg
6. • Daily kilocalorie requirement (KCAL)
7. • BMI (Body Mass Index)

The results will display in a cycle. After three repetitions, the scale will automatically turn off.

Notice

There must not be a contact between feet, calves or thighs. Otherwise the measurement could be inaccurate.

For a repeated analysis of body characteristics (after saving the input data of the person to the memory – e.g. 1), proceed as follows:

1) Press the button (if you were using the scale in the regular weighing mode).
2) Wait for 0.0 on the display or choose the number of memory with the ▲ or ▼ button where your setting is saved.
3) Do not press anything after selecting the respective number of memory (wait till 0.0 appears). Step on the scale and your weight and bodily characteristics will begin to be analyzed.

Note

The scale is switched on automatically if you do not step on it within approx. 20 seconds after „0.0“ is displayed.
