Frequently Asked Questions - KFW 5028 KORONA

How to install the batteries of the Korona KFW 5028 scale?

Remove the battery protective strip or insert the batteries according to the indicated polarity. If the screen does not turn on, remove the batteries and reinstall them. Use batteries of the same type, brand, and capacity.

Why does the screen display "EE"?

The "EE" error may indicate exceeding the maximum load (180 kg) or too high electrical resistance between the electrodes and the soles of the feet (dry feet or calluses). In this case, repeat barefoot and slightly moisten the soles of the feet.

How to set user data (age, height, gender)?

Make sure the scale is in standby. Press MEM, select a memory location with ▲/▼, then press and hold SET. Follow the steps to set height, age, gender, and athlete mode. Confirm each step with SET.

Can the scale be used if you have a pacemaker or are pregnant?

No, the scale should not be used by persons with medical implants (pacemaker) or by pregnant women, as this could affect the implant's function or the measurement.

How to clean the scale?

Clean it from time to time with a damp cloth. Do not use aggressive products, never immerse the scale in water, and do not put it in the dishwasher.

Why does the displayed weight vary from day to day?

Only long-term trends matter. Short-term variations are often due to water loss or gain. Weigh yourself on an empty stomach, at the same time, and without clothes for comparable results.

How to switch from kg to lb or stone?

At the back of the scale there is a button to change the unit. Press it multiple times to toggle between kg, lb, and st:lb.

What does the message "LO" on the screen mean?

The "LO" message indicates that the batteries are almost depleted. Replace them with new batteries of the same type.

How to use the target weight analysis function?

During setup, activate the target weight analysis by selecting "Yes" after choosing "Goal". Then set the desired target weight. With each weighing, the scale will display progress as a bar graph.

Why does the scale not turn on when I step on it?

The scale must first be activated. Briefly press the scale with your foot until "0.0 kg" displays, then step on. If it does not turn on, check the batteries.

5. Initial use

Inserting the batteries

Please remove the plastic insulating strip and/or position the batteries the correct way round. If the scale fails to operate, remove the batteries completely and reinsert them.

Changing the weight unit

The scale shows the values in kg. On the back of the device, there is a button that you can use to switch the units between kilograms (kg), pounds (lb) and stone (st:lb), by pressing it several times.

Setting up the scale

Set up the scale on a level and solid surface. A solid surface is a prerequisite for a correct measurement.

6. Information

General tips

• If possible, always weigh yourself at the same time of day (preferably in the morning), after using the toilet, on an empty stomach and unclothed, in order to achieve comparable results.
• Important for the measurement: only measure body fat 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 and upright during the measurement.
• Wait a few hours after unaccustomed physical activity.
• Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute.
• Remember that only long-term trends are important. Short-term changes in weight within a few days are usually caused by a loss of fluid. Body water plays an important role towards our general wellbeing.

Limitations

When measuring body fat and other values, deviating and implausible results may occur in:

• children under approx. 10 years,
• competitive athletes and body builders,
- persons with fever, undergoing dialysis treatment or with symptoms of edema or osteoporosis,
- persons taking cardiovascular medication (affecting the heart and vascular system),
- 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).

7. Settings

You must enter personal user parameters in order to measure your body fat percentage and other physical data.

The scale has 10 user memory locations which allows, for example, you and your family members to save personal settings and retrieve them later:

User data Parameters
Memory position 1 to 10
Sex	male (23C4) female
Age 10 to 99 years
Body height 100 to 220 cm	(3’-03” to 7’-2,5”)
Athlete mode	Physical exercise leads to a specific metabolism and high muscle density. This leads to an increase in the body’s resistance. So that this increased resistance is not wrongly interpreted as fat, you can adapt the measurement parameters to suit different (sport-related) physical conditions.

Setting user data

Check that the scale is in standby mode and that there are no values or symbols in the display. If this is not the case, wait for a few seconds until the display clears automatically.

1. Press MEM and "User 1" will appear in the display.

1. Touch the scale and wait until 0,0 kg appears.

1. Step onto the scale and stand still.

1. After a few seconds, your weight will be displayed.

After displaying the weight, the scales automatically switch off.

9. Evaluation of results

Body fat percentage

The body fat values are shown in the display. The following body fat percentages are guide values (contact your physician for further information). The body fat chart that is also shown on the display (at the bottom) is only to provide more simple orientation.

A lower value is often found in athletes. Depending on the type of sports, training intensity and physical constitution, 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.

① Severely underweight ④ Overweight
② Underweight ⑤ Obese
③ Normal

Body water percentage

The body water percentage is normally within the following ranges:

Men Women

Age poor good	good very good	good Age poor	good very good	d
10-100<50	50-65>65	10-100<45	45-60>60

Body fat contains relatively little water. Therefore persons with a high body fat percentage have body water percentages below the recommended values. With endurance athletes, however, the recommended values could be exceeded due to low fat percentages and high muscle percentage.

This scale is unsuitable for measuring body water in order to draw medical conclusions concerning age-related water retention, for example. If necessary ask your physician. Basically, a high body water percentage should be the aim.

Target weight analysis

An additional feature is the ability to enter a target weight. This means that a progress check can be carried out and calculated automatically by the scale with each weighing; a percentage is then shown on the display in chart form. At each weighing, the last recorded weight is also displayed.

Results in relation to time

Remember that only long-term trends are important. Short-term fluctuations in weight over a few days are usually the result of a loss of fluid.

The interpretation of the results reflects changes in total body weight, percentage of body fat and body water as well as muscle density, and takes into account the length of time over which these changes take place. Sudden changes 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. This way you can increase your muscle percentage over the medium term.
• Body fat, body water or muscle percentages should not be added (certain elements of muscle tissue also contain body water).

10. Replacing batteries

The batteries in the scales must be replaced if the message “LO” appears in the display. If the batteries are too flat, then the scales will switch off automatically.

Note

• When changing batteries, always use batteries of the same type, brand and capacity.
  • Always replace all batteries simultaneously.
• Do not use rechargeable batteries.
• Use batteries that are free of heavy metals.

11. Storage and maintenance

The precision of the measurements and service life of the device depends on its careful handling:

Important

• The unit should be cleaned occasionally. Do not use abrasive detergents and never immerse the unit in water.

• Make sure that no liquids come into contact with the scales. Never submerge the scales in water. Never rinse them in running water.

• Do not stand any objects on the scales when not in use.

• Protect the scales from knocks, damp, dust, chemicals, drastic changes in temperature, electromagnetic fields and nearby sources of heat (ovens, heaters). Do not press the buttons violently or with pointed objects.
• Do not wash the unit in a dishwasher!

If the scale detects and error when measuring, the following is displayed.

Display Cause Remedy
EE	The maximum load capacity of 180 kg was exceeded.	Do not load the unit with over 180 kg.
Lo	The batteries are almost empty. Replace the batteries.
EE	The electrical resistance between the electrodes and the sole of your foot is too high (e.g. if you have tough calluses).	Repeat the measurement barefoot. If necessary, moisten the soles of your feet slightly. If necessary, remove the calluses from the soles of your feet.
	The fat percentage is outside the measurable range (less than 4% or greater than 55%).	Repeat the measurement barefoot or, if necessary, moisten the soles of your feet slightly.

No measurement possible

Possible errors Remedy
The scale was not activated before you stood on it. If you step on the scale before “0.0 kg” is displayed, the scale will not work correctly.	Activate the scale correctly (wait for “0.0 kg”) and repeat the measurement.
The batteries in the scale are empty. Replace the batteries.

Incorrect weight measurement

Possible errors Remedy
Scale is on carpeting. Place the scale on a level and	solid surface.
