Getting to know your device

Functions of the device

This digital scale is intended for weighing and providing a diagnosis of your personal fitness data. It is intended for private use.
The scale is equipped with the following functions, which can be used by up to 8 people:

Body weight measurement and BMI,
Body fat percentage calculation,
Body water content,
Muscle percentage,
Bone mass,
Basal and active metabolic rate.

The scale also includes the following additional features:

Switch between kilograms "kg", pounds "lbs" and stones "st",
Automatic switch-off function,
Low battery indicator,
Automatic user recognition,
LCD display of 3 user initials,
Storage of the last 30 measurements for 8 users, if the data cannot be transferred to the app.

The measurement principle

This scale works on the principle of B.I.A. (bioelectrical impedance analysis). This involves the calculation of body content in a matter of seconds, using a current that cannot be felt, is completely harmless and does not pose any risk.
When this measurement of the electrical resistance (impedance) is considered alongside constants and/ or individual values (age, height, gender, activity level), the body fat percentage and other variables in the body can be calculated. Muscle tissue and water conduct electricity well and therefore have a lower resistance. In contrast, bones and fat tissue have low conductivity as the fat cells and bones are barely able to conduct the current due to very high levels of resistance.
Please note that the values calculated by the diagnostic bathroom scale only represent an approximation of the actual medical analytical values for the body. Only a specialist doctor can precisely establish the body fat, body water, muscle percentage and bone structure using medical methods (e.g. computer tomography).

Initial use

Inserting the batteries
Remove the batteries from the protective packaging and insert the batteries into the scale ensuring that the battery polarity is correct. If the scale does not function, remove the batteries completely and reinsert them.

Positioning the scale
Place the scale on an even, hard surface; a hard surface is crucial for achieving accurate measurements.

Initial use with the app

To be able to calculate your body fat percentage and additional body values, you must save the personal user data on the scale.
The scale has 8 user memory spaces which allow, for example, you and your family members to save personal settings.
It is also possible to activate users via other mobile end devices on which the "beurer HealthManager" app has been installed or by changing the user profile in the app (see the app settings).
Keep the smartphone close to the scale in order to maintain an active Bluetooth^® connection during initial use.

Download the free "beurer HealthManager" app from the Apple App Store (iOS) or from Google Play (Android™).
Start the app and follow the instructions.
Select BF 720 in the app.

Enter the BF 720-related data.
The following settings must be set or entered in the "beurer HealthManager" app:

User data	Set values
Initials/abbreviation of name	Max. 3 letters or numbers
Height	100 to 220 cm (3'3.5" to 7'2.5")
Age	10 to 100 years
Gender	Male (), female ()
Activity level	1 to 5

Activity levels
The medium-term and long-term perspective is decisive when selecting the activity level.

Activity level	Physical activity
1	None.
2	Low: little and light physical exertion (e.g. going for walks, light gardening, simple gymnastics).
3	Medium: physical exertion, at least 2 to 4 times a week for 30 minutes each.
4	High: physical exertion, at least 4 to 6 times a week for 30 minutes each.
5	Very high: intensive physical exertion, intensive training or hard physical work for at least 1 hour every day.

Assign the user when requested to do so by the app.
For automatic personal recognition, the first measurement must be assigned to your personal user data. Follow the app instructions for this. Step onto the scale with bare feet and ensure that you are standing still with equal weight distribution and with both feet on the electrodes.
Note: Only the measurements displayed on the scale may be used for further observations.

Initial use without the app (alternative)

Note:
We recommend using the "beurer HealthManager" app for initial use and implementing all settings. Therefore, only carry out this step if initial use is to be carried out entirely without the app. If you have performed initial use with the app, go directly to the "Taking measurements" chapter.

After inserting the batteries, "USE APP" will flash in the display. Press the SET button to set the year/month/day, as well as hour/minute.
To do this, press the buttons.
Confirm with the SET button. "0.0" appears in the display.
Now press the SET button again. The display will show "P-01" or the number of the scale user memory which was most recently used.
Select your user memory (P-01 to P-08) with the buttons and press the SET button to confirm.
Implement your settings such as gender and initials, height, etc. (See "Initial use with the app" (table)). Confirm each setting by pressing the SET button.
The 4-digit user PIN appears once you have finished entering your details. This will be required for logging into the app at a later time. "0.0" will then appear in the display, along with your initials.
For automatic personal recognition, the first measurement must be assigned to your personal user data. Step onto the scale, ideally with bare feet, and ensure that you are standing still with equal weight distribution, with both feet on the electrodes.

information Note on logging into the app at a later time:
If you have carried out the initial use of the scale without the app, you can add your existing scale user memory to the "beurer HealthManager" app. This requires you to enter your 4-digit user PIN. This process is described in the app.

Usage

Taking measurements

Place the scale on an even, hard surface; a hard surface is crucial for achieving accurate measurements.

Measuring your weight, carrying out diagnostics
Step onto the scale with bare feet and ensure that you are standing still with equal weight distribution and with both feet on the electrodes.
Note: The measurement result will be incorrect if the measurement is taken with socks on.
The scale begins to take measurements straight away. First, the weight is displayed.
If a user has been assigned, the BMI, body fat, water, muscle, bone, BMR and AMR are shown. This is the case if the initials are shown.
The following appears:

Weight in kg with BMI
Body fat in % (BF)
Body water in %
Muscle percentage in %
Bone mass in kg
Basal metabolic rate in kcal (BMR)
Active metabolic rate in kcal (AMR)

Note: If two or more users have potentially been recognised, the display switches between them. Select your user by pressing the button.
If no user is recognised, only the weight and "" will be displayed. You can then use the buttons to select your user. Otherwise the measurement will not be saved.

Only measuring weight
Now step onto the scale wearing shoes. Stand still with your weight distributed equally on both feet. The scale begins to take measurements straight away.
If a user has been assigned, the BMI will be displayed. This is the case if the initials are shown.
If the user is not recognised, only the weight can be shown and no initials appear "".

Switching off the scale
The scale switches itself off automatically.

Evaluating the results

Body fat percentage
The following body fat percentages serve as a guideline (for further information please consult your doctor).

Age	Low	Normal	Moderate	High
Male
10–14	<11%	11–16%	16.1–21%	>21.1%
15–19	<12%	12–17%	17.1–22%	>22.1%
20–29	<13%	13–18%	18.1–23%	>23.1%
30–39	<14%	14–19%	19.1–24%	>24.1%
40–49	<15%	15–20%	20.1–25%	>25.1%
50–59	<16%	16–21%	21.1–26%	>26.1%
60–69	<17%	17–22%	22.1–27%	>27.1%
70–100	<18%	18–23%	23.1–28%	>28.1%
Female
10–14	<16%	16–21%	21.1–26%	>26.1%
15–19	<17%	17–22%	22.1–27%	>27.1%
20–29	<18%	18–23%	23.1–28%	>28.1%
30–39	<19%	19–24%	24.1–29%	>29.1%
40–49	<20%	20–25%	25.1–30%	>30.1%
50–59	<21%	21–26%	26.1–31%	>31.1%
60–69	<22%	22–27%	27.1–32%	>32.1%
70–100	<23%	23–28%	28.1–33%	>33.1%

Values will often be lower for fitness enthusiasts. Depending on the sporting activities performed, the training intensity and the physical constitution, the results may still be below the stated standard values. Please note, however, that there may be a risk to health in the case of extremely low values.

Body water content
The body water content in % is normally within the following ranges:

Age	Poor	Good	Very good
Male
10–100	<50%	50–65%	>65%
Female
10–100	<45%	45–60%	>60%

Body fat contains relatively little water, therefore body water content may be below the standard values in persons with a high body fat percentage. On the other hand, endurance athletes may exceed the standard values due to having low levels of fat and a high muscle percentage.
The body water calculation performed using this scale is not suitable for drawing medical conclusions, for example in the case of age-related water retention. Consult your doctor where necessary. A high body water content is generally desirable.

Muscle percentage
The muscle percentage is normally within the following ranges:

Age	Low	Normal	High
Male
10–14	<44%	44–57%	>57%
15–19	<43%	43–56%	>56%
20–29	<42%	42–54%	>54%
30–39	<41%	41–52%	>52%
40–49	<40%	40–50%	>50%
50–59	<39%	39–48%	>48%
60–69	<38%	38–47%	>47%
70–100	<37%	37–46%	>46%
Female
10–14	<36%	36–43%	>43%
15–19	<35%	35–41%	>41%
20–29	<34%	34–39%	>39%
30–39	<33%	33–38%	>38%
40–49	<31%	31–36%	>36%
50–59	<29%	29–34%	>34%
60–69	<28%	28–33%	>33%
70–100	<27%	27–32%	>32%

Bone mass
Like the rest of our body, our bones are subject to natural growth, shrinking and ageing processes. Bone mass increases rapidly during childhood and reaches its peak between the ages of 30 and 40. As we age, our bone mass then begins to reduce. You can combat this reduction to an extent with the help of a healthy diet (particularly calcium and vitamin D) and regular physical exercise. The stability of your skeleton can be further increased by means of targeted muscle build-up. Please note that this scale does not identify the total bone mass, but rather just the mineral content of the bone (without water content and without organic substances). It is very difficult to influence the bone mass, although it does fluctuate slightly within the scope of influencing factors (weight, height, age, gender). There are no recognised guidelines or recommendations.

Please do not confuse bone mass with bone density.
The bone density can only be determined by means of a medical examination (e.g. computer tomography, ultrasound). It is therefore not possible to draw conclusions on changes to bones and bone hardness (e.g. osteoporosis) using this scale.

BMR
The basal metabolic rate (BMR) is the amount of energy required by the body at complete rest in order to maintain its basic functions (e.g. when lying in bed 24 hours a day). This value is primarily dependent on weight, height and age.
It is displayed on the diagnostic bathroom scale in the kcal/day unit and is calculated using the scientifically recognised Harris-Benedict equation.
This is the amount of energy that is required by your body under all circumstances and must be re-supplied to the body in the form of food. If your energy intake is below this level in the longer term, this can result in damage to health.

AMR
The active metabolic rate (AMR) is the amount of energy that the active body consumes each day. An individual's energy requirement increases when the level of physical activity increases; the diagnostic bathroom scale calculates this by means of the activity level (1–5) that has been entered.
To maintain the current weight, the energy that the body uses must be replaced in the form of food and drink.
If less energy is taken in than is used over a long period of time, the body primarily takes the difference from the fat stores, with resulting weight loss. However, if the amount of energy taken in exceeds the calculated active metabolic rate (AMR) for a longer period, the body cannot burn off the excess energy. The excess is stored in the body as fat, leading to weight gain.

Temporal context of the results

Note: Please note that only the long-term trend is important. Brief deviations in weight within a few days are normally caused by loss of fluids.
The interpretation of the results is based on changes in total body weight, percentage of body fat, body water and muscle content, as well as on the length of time over which these changes occur.
Rapid changes within the scope of a few days are to be considered separately from medium-term changes (in the scope of weeks) and long-term changes (months).
It can be said as a basic rule that short-term changes in weight are almost entirely changes in water content, whereas medium-term and long-term changes may also relate to the fat percentage and the muscle percentage.

If your weight drops in the short term but your body fat percentage increases or stays the same, you have only lost water, for example following a training session, visit to the sauna or a diet aimed only at fast weight loss.
If your weight increases in the medium term and your body fat percentage drops or stays the same, you may have built up valuable muscle mass.
If your weight and body fat percentage both fall at the same time, then your diet is working – you are losing fat mass.
Ideally, you should support your diet with physical activity, fitness or strength training. This enables you to increase your muscle percentage in the medium term.
Body fat, body water and muscle percentages should not be totalled (muscle tissue also contains components made of body water).

Other functions

User assignment

It is possible to assign up to 8 scale users for a weight-only measurement (with shoes) and for a diagnosis measurement (bare feet).
For a new measurement, the scale assigns the measurement to the user whose most recently saved measurement falls within +/- 3kg. If two or more users have potentially been recognised, the display switches between them. Select your user by pressing the button.

Saving the assigned measurements on the scale

If the app is open and there is an active Bluetooth^® connection to the scale, newly assigned measurements are transferred immediately to the app. In this case, the values are not saved on the scale. If the app is not open, the newly assigned measurements are saved on the scale. A maximum of 30 measurements per user can be saved on the scale. If all 30 measurements are fully assigned, the synchronisation symbol in the scale display flashes and you should transfer the measured values to the app in order that you do not overwrite older measured values. The saved measurements are transferred automatically to the app when you open the app within the Bluetooth^® range.
It is possible to automatically transfer data when the scale is switched off. The synchronisation symbol on the scale display appears when new measurements are being transferred to the app. It does not appear if no new measurements have been saved or assigned for this user.

Call-up of saved measured values on the scale

If you would like to view your saved measured values on the scale, press the button when the scale is switched on and whilst you are displaying your scale user; this may need to be done several times if required in order to call up several older values.
Measured values that have already been transferred can no longer be viewed on the scale display.

Deleting scale data

If you would like to completely delete all measurements and old user data on the scale, switch on the scale and press the Mode button on the rear of the scale for approx. 6 seconds.
"CLR" will appear on the display for several seconds.
This is necessary if you would like to delete scale users who have been set up incorrectly or are no longer required, for example.
You must then carry out the actions in chapter "Usage"(on user assignment) again.

Deleting individual users

Switch on the scale, select the user using the UP button and wait until "0.0 kg" appears; press the Mode button for 6 seconds until "DEL" appears.

Replacing the batteries

Your scale is equipped with a low battery indicator. If you operate the scale with flat batteries, "Lo" will appear on the display and the scale will automatically switch off. In this case, the batteries must be replaced (3 x 1.5 V AAA).
NOTE:

When replacing the batteries, use batteries of the same type, make and capacity.
Do not use rechargeable batteries.
Use batteries free from heavy metals.

Cleaning and maintenance

The device should be cleaned from time to time.
This should be done using a damp cloth and, if necessary, a small amount of detergent.

Never use abrasive solvents or cleaning products!
Never submerge the device in water!
Do not clean the device in a dishwasher!

Do not use rechargeable batteries!
Do not disassemble, open or crush the batteries.

information General notes

Please note that measuring tolerances are possible for technical reasons, as this scale is not calibrated for use in a professional medical context.
The scale's maximum capacity is 180 kg (396 lb/28 st). The results for the weight measurement and bone mass calculation are displayed in 100-g increments (0.2 lb).
Measurements of body fat, body water and muscle content are displayed in increments of 0.1%.
The calorie requirement is indicated in increments of 1 kcal.
When supplied to the customer, the scale is set to weigh and measure in "cm" and "kg". You can change the unit settings during initial use with the app.
Place the scale on an even, hard surface; a hard surface is crucial for achieving accurate measurements.
Repairs may only be carried out by Beurer Customer Services or authorised retailers. Before submitting a complaint, please check the batteries first and replace them if necessary.

Storage and maintenance
The accuracy of the measurements and service life of the device depend on its careful handling:

The device should be cleaned from time to time. Do not use any abrasive cleaning products and never submerge the device in water.
Make sure that no liquids come into contact with the scale. Never submerge the scale in water. Never rinse it in running water.
Do not place any objects on the scale when it is not in use.
Do not press the button violently or with pointed objects.
Do not expose the scale to high temperatures or strong electromagnetic fields (e.g. mobile telephones).
Protect the device from knocks, damp, dust, chemicals, marked temperature fluctuations and nearby sources of heat (ovens, heaters).

General tips

As far as possible, weigh yourself at the same time every day (ideally in the morning), after having been to the toilet, on an empty stomach and without clothing, in order to obtain results which can be compared.
Important point regarding the measurement: the calculation of body fat may only be made when barefoot; the soles of the feet may be lightly dampened where appropriate. Results may be unsatisfactory if the soles of the feet are completely dry or have a large amount of hard skin since conductivity will be impaired.
Stand up straight and still during the measurement.
Wait a few hours after any physical exertion to which your body is unaccustomed.
Wait approx. 15 minutes after getting up so that the water stored in the body can disperse.
Remember that only the long-term trend is important. Short-term changes in weight within a few days are normally caused by loss of fluids; however, body water plays an important role in terms of well-being.

Limitations
When calculating body fat and the other values, unusual and implausible results may occur in the case of:

Children under approx. 10 years of age
Performance athletes and body-builders
Persons with a fever, persons undergoing dialysis, persons with oedema symptoms and persons suffering from osteoporosis
Persons taking cardiovascular medicine (affecting the heart and vascular system)
Persons taking vasodilative or vasoconstrictive medication
Persons with significant anatomical abnormalities in their legs compared with their overall body height (leg length significantly shorter or longer).
