For transmitters rated at a maximum output power not listed above, the recommended 

separation distance d in meters (m) can be estimated using the equation applicable to the 

frequency of the transmitter, where P is the maximum output power rating of the transmitter in 

watts (W) according to the transmitter manufacturer.

NOTE 1: 

At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE 2: 

These guidelines may not apply in all situations. Electromagnetic propagation is aff ected 

by absorption and refl ection from structures, objects and people.

Model MED-53

4.  INTENDED USE

The digital automatic blood pressure monitor is suitable for home healthcare 

environment and is a non-invasive blood pressure measurement system intended to 

measure the diastolic and systolic blood pressures and pulse rate of an adult individual 

by using a non-invasive technique in which an infl atable cuff is wrapped around the 

upper arm. The cuff circumference is limited to 22 cm-42 cm.

5.  CONTRAINDICATION

It is inappropriate for people with skin wounds on upper arms.

6.  PRECAUTIONS

1.  Before use, please read this instruction manual carefully. 

2.  In case of questions on the use of blood pressure monitor and resulting blood 

pressure values, please contact a doctor.

3.  Keep MED-53 out of the reach of children. 

4.  Do not use MED-53 near anesthetic, fl ammable or oxygen mixture, or with nitrous 

oxide.

5.  Do not forget: self-measurement means control, not diagnosis or treatment. 

Unusual values must always be discussed with a doctor. Under no circumstances a 

treatment should be altered or changed without a doctor’s prescription. 

6.  The pulse display is not suitable for checking the frequency of heart pacemakers.

7.  In cases of cardiac irregularity (I.H.B.), measurements made with this device should 

only be evaluated after consultation with a doctor.

8.  Changes to the unit by the user are not admitted.

9.  We recommend consulting a doctor before using the blood pressure monitor on 

patients with pre-eclampsia or during pregnancy.

10.  The device does not require any calibration.

11.  Tubing kinking can cause continuous cuff pressure and may result in blood fl ow 

interference and patient injury.

12.  Too frequent measurements can cause injury to the patient due to blood fl ow 

interference.

13.  Please note that, when infl ating, the functions of the limb in question may be 

impaired.

14.  During the blood pressure measurement, the blood circulation must not be 

stopped for an unnecessarily long time.

15.  If the device malfunctions remove the cuff from the arm.

16.  The user must check that the equipment functions safely and see that all its parts 

are in proper conditions before use.

17.  Please always relax a minimum moment of 1-1,5 minutes between measurements 

to allow the blood circulation in your arm to recover. Prolonged over-infl ation 

(cuff pressure exceed 300 mmHg or maintained above 15 mmHg for longer than 3 

minutes) of the bladder may cause ecchymoma of your arm.

18.  Consult your physician if you have any doubt about below cases:

1) The application of the cuff over a wound or infl ammation diseases;

2) The application of the cuff on any limb where intravascular access or therapy, or 

an arterio-venous (A-V) shunt, is present;

3) The application of the cuff on the arm on the side of a mastectomy;

4) Simultaneously used with other monitoring medical equipments on the same limb.

19.   This automatic blood pressure monitor is designed for adults and should never 

be used on infants or young children. Consult your physician or other health care 

professionals before use on older children.

20. Do not use this unit in a moving vehicle. This may result in erroneous 

measurement.

21.  Blood pressure measurements determined by this monitor are equivalent to those 

obtained by a trained observer using the cuff/stethoscope auscultation method, 

within the limits prescribed by the American National Standard Institute, Electronic 

or automated sphygmomanometers.

22. Information regarding potential electromagnetic or other interference 

between the blood pressure monitor and other devices together with advice 

regarding avoidance of such interference please see part ELECTROMAGNETIC 

COMPATIBILITY INFORMATION.

23. Please do not use the cuff other than supplied by the manufacturer, otherwise it 

may bring biocompatible hazard and might result in measurement error.

24.   The monitor might not meet its performance specifi cations or cause safety 

hazard if stored or used outside the specifi ed temperature and humidity ranges in 

specifi cations.

25.   Please do not share the cuff with other infective person to avoid cross-infection.

7.8. Pulse Arrhythmia Detection

The appearance of the symbol  

  signifi es that a certain pulse irregularity was 

detected during the measurement. The result can vary from your normal blood 

pressure. It is better to repeat the measurement. As a rule this is not a cause for 

concern; however, if the symbol 

 appears more frequently (e.g. several times 

per week on measurements performed daily) or if it suddenly appears more often 

than usual, we recommend you inform your doctor.

7.9. Traffi c Light Indication

The colored bars on the left-hand edge of the display show you the range within 

which the indicated blood pressure values lies. Depending on the height of the bar, 

the readout value is either within the normal (green), borderline (yellow and orange) 

or danger (red) range. If the values of systole and diastole fall into two different 

categories (e.g. systole in the High normal category and diastole in the Normal 

category), the graphical classifi cation on the device always shows the higher category 

(e.g. High).

The classifi cation corresponds to the 6 ranges in the Table as defi ned by the ESH and 

described on the table of the point 2. The recommendations of the European Society of 

Hypertension (ESH) allow to diagnose and treat the hypertension more effectively and 

do not contradict World Health Organization recommendations.

Please note that these standard values serve only as a general guideline, as the 

individual blood pressure varies in different people and different age groups etc., it is 

important to consult your doctor regularly for advice.

7.2. Using a mains adapter

1)   Plug the mains adapter into a 110-240 V, 50/60Hz power socket.

2)   Plug the Micro USB plug into the USB port at the left side of the device.

Micro USB port is for power supply only. The USB port can’t be used for data 

downloading.

  If you need an adapter, you may purchase it separately. B.Well recommends to use 

the B.Well Micro USB adapter for MED-53 device. Please use certifi ed Micro USB 

adapters which output is 6V DC 600 mA.

7.3. Setting time and date

a.  Once batteries are inserted and device still in OFF mode, years digit blinks on the 

display. See picture 3-1.

b.  Press “M” button to advance the year. If you keep the button depressed for more 

than 3 seconds, you can switch more quickly to the desired digit.

c.  Press “Time” button to confi rm and switch to the month value. See picture 3-2.

d.  Press “M” button to advance the month.

e.  Repeat the above described procedure to set day, hour and minutes.

See picture 3-3.

f.  At the end of the procedure, press “Time” button to confi rm current setting and 

go in OFF mode.

The display will now show clock and date. If you need to correct the time or date 

press and hold “Time” for 3 seconds until years digit blinks on the display. Every 
time batteries are changed, time and date settings are kept.

7.4. Connecting the cuff to the monitor

a.  Insert the Air tube plug fi rmly into the Air tube socket on the side of the monitor. 

Make certain that the Plug is completely inserted in order to prevent air leakage 

during use. 

  Avoid compression or restriction of the connection tubing during measurement, 

which may cause infl  ation error, or harmful injury due to continuous cuff 
pressure.

7.5. Applying the cuff

a.  Remove any garment that fi ts closely to your upper arm.

b.  Pulling the cuff end through the medal loop (the cuff is packaged like this already), 

turn it outward (away from your body) and tighten it and close the Velcro fastener.

с.  Place a cuff around a naked hand 2-3 cm higher than an elbow pole. Arrange a cuff 

on a hand so that the red tag (Artery mark) is over an elbow pole.

d.  There must be no free space between the arm and the cuff. Clothing must not 

restrict the arm. Any piece of clothing which does (e.g. a pullover) must be taken 

off. The cuff has to cover densely a hand, otherwise the result of measurement will 

be the improper.

7.6. Carrying out a measurement
Before the measurement:

  Avoid eating, smoking as well as all forms of exertion directly before the 

measurement. All these factors infl  uence the measurement result. Try and fi nd 

time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes 

before the measurement.

  Measure always on the same arm.

  Attempt to carry out the measurements regularly at the same time of day, since 

the blood pressure changes during the course of the day.

Sitting Comfortably Measurement:

a.  Be seated with your feet fl at on the fl oor, and don’t cross your legs.

b.  Place palm upside in front of you on a fl at surface such as a desk or table. Make 

sure to be sit in a comfortably position with your arms extended and back leaning 

on the seatback.

c.  The middle of the cuff should be at the level of the heart. To avoid errors in the 

measurement, it is important to remain immobile during the measurement and in 

silence.

Common sources of error:

  Movement during measurement

  The arm artery lies considerably lower (higher) than the heart

  The cuff does not fi t you in size

  Loose cuff or a sideways protruding air-pocket

Warning:

 Only use original cuffs!

With repeated measurements, blood accumulates in the respective arm, which can 

lead to false results. Correctly executed blood pressure measurements should 
therefore fi rst be repeated after a 1 minute pause.

7.7.  Taking your blood pressure reading

a.  After the cuff has been appropriately positioned, press “Start” button to start 

measure. “0” appears in “DIA” fi eld: the monitor is ready for the measurement. 

See Picture 7-1.

b.  Cuff infl ation starts and display shows increasing pressure values in “DIA” fi eld. The 

“Cuff position control” symbol is displayed throughout the entire measurement. See 

Picture 7-2. If the cuff is applied too tightly or too loosely, then the Error symbol E3 

is displayed and the “Cuff position control” symbol is blinking.

c.  As the heartbeat is detected, the “Heart beat” symbol blinks and a beeping sound 

is generated at the same rhythm of the heartbeat. When the measurement is 

completed, cuff is defl ated. The display shows the systolic / diastolic pressure 

and pulse. See Picture 7-3. WHO segments on the left of the display show 

pressure result according to WHO scale (see following dedicated paragraph for 

detailed explanation).

d.  After measurement, the monitor will turn off automatically after 1 minute of no 

operation. Alternatively, you can press the “Start” button to turn off the monitor 

manually.

During measurement, you can press the “Start” button to turn off the monitor 

manually.

NOTE:

Please consult a health care professional for interpretation of pressure 

measurements.
