ŸThe need to check that operation of the automated sphygmomanometer does not result in
prolonged impairment of patient blood circulation.
ŸNot intended to be used together with HF surgical equipment.
ŸDo not forget: self-measurement means control, not diagnosis or treatment. Unusual values
must always be discussed with your doctor. Under no circumstances should you alter the
dosages of any drugs prescribed by your doctor.
ŸThe pulse display is not suitable for checking the frequency of heart pacemakers!
ŸIn cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should
only be evaluated aer consultation with the doctor.
1. INTRODUCTION
Aention
1.2. Important information about self-measurement
ŸSubstitution of a different component might result in measurement error.
ŸCuff is replaceable only by an original.
ŸDo not use with neonatal patients.
ŸIt will cause harmful injury to the patient or effect the blood pressure due to connection tubing
kinking.
ŸToo frequent measurements can cause injury to the patient due to blood flow interference.
ŸThe application of the cuff over a wound can cause further injury.
ŸThe application of the cuff and its pressurization on any limb where intravascular access or
therapy, or an arteriovenous (A-V) shunt, is present because of temporary interference to blood
flow and could result in injury to the patient.
ŸDo not let the cuff and its pressurization on the arm on the side of a mastectomy
Electromagnetic interference
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong
electrical or electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones,
microwave cookers). These can lead to temporary impairment of the measuring accuracy.
2. IMPORTANT INFORMATION ON THE SUBJECT OF
BLOOD-PRESSURE AND ITS MEASUREMENT
2.1. How does high/low blood-pressure arise?
The level of blood-pressure is determined in a part of the brain, the so-called circulatory center, and
adapted to the respective situation by way of feedback via the nervous system. To adjust the blood-
pressure, the strength and frequency of the heart (Pulse), as well as the width of circulatory blood
vessels is altered.
124

The laer is affected by way of fine muscles in the blood-vessel walls. The level of arterial blood-
pressure changes periodically during the heart activity: During the «blood ejection» (Systole) the
value is maximal (systolic blood-pressure value), at the end of the heart’s «rest period» (Diastole)
minimal (diastolic blood-pressure value). The blood-pressure values must lie within certain normal
ranges in order to prevent particular diseases.
6 7
2.2. Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic
blood-pressure is over 160 mmHg. In this case, please consult your doctor immediately. Long-term
values at this level endanger your health due to the associated advancing damage to the blood
vessels in your body.
Should the systolic blood-pressure values lie between 140 mmHg and 160 mmHg and/or the diastolic
blood-pressure values lie between 90 mmHg and 100 mmHg, likewise, please consult your doctor.
Furthermore, regular self-checks will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 100 mmHg and/or diastolic
values under 60 mmHg, likewise, please consult your doctor. Even with normal blood-pressure values,
a regular self-check with your blood-pressure monitor is recommended. In this way you can detect
possible changes in your values early and react appropriately. If you are undergoing medical
treatment to control your blood pressure, please keep a record of the level of your blood pressure by
carrying out regular self-measurements at specific times of the day. Show these values to your doctor.
Never use the results of your measurements to alter independently the drug doses prescribed by
your doctor.
Table for classifying blood-pressure values (unit: mmHg) according to World Health Organization:
Range Systolic
Blood pressure
Diastolic
Blood-pressure
Measures
optimum between 100 and 120 between 60 and 80 Self-check
normal between 120 and 129 between 80 and 84 Self-check
high to normal between 130 and 139 between 85and 89 Consult your doctor
slight hypertension between 140 and 159 Between 90and 99 Seek medical advice
medium hypertension between 160 and 179 Between 100and 109 Seek medical advice
strong hypertension Higher than 180 Higher than 110 Urgently seek
medical advice!
Further information
ŸIf your values are mostly standard under resting conditions but exceptionally high under
conditions of physical or psychological stress, it is possible that you are suffering from so-called
«labile hypertension». Please consult your doctor if you suspect that this might be the case.
ŸCorrectly measured diastolic blood-pressure values above 120mmHg require immediate medical
treatment.

5. CARRYING OUT A MEASUREMENT
5.1. Before the measurement
ŸAvoid eating, smoking as well as all forms of exertion directly before the measurement. All these
factors influence the measurement result. Try and find time to relax by siing in an armchair in a
quite atmosphere for about ten minutes before the measurement.
ŸMeasure always on the same arm (normally le).
ŸAempt to carry out the measurements regularly at the same time of day, since the blood-
pressure changes during the course of the day.
5.2. Common sources of error
ŸNote: Comparable blood-pressure measurements always require the same conditions! These are
normally always quiet conditions.
124

ŸAll efforts by the patient to support the arm can increase the blood-pressure. Make sure you are
in a comfortable, relaxed position and do not activate any of the muscles in the measurement
arm during the measurement. Use a cushion for support if necessary.
ŸThe performance of the automated sphygmomanometer can be affected by extremes of
temperature, humidity and altitude.
ŸAvoid compression or restriction of the connection tubing.
ŸA loose cuff causes false measurement values.
ŸWith repeated measurements, blood accumulates in the respective arm, which can lead to false
results. Correctly executed blood-pressure measurements should therefore first be repeated
aer a 5 minutes pause or aer the arm has been held up in order to allow the accumulated blood
to flow away (aer at least 3 minutes).
12 13
a) The distance between the edge of cuff and the elbow
should be approx. 2~3cm
Aention
5.3. Fiing the cuff
Insert air connector into air outlet shown in
le photo and please make sure the fiing of
the air connector completely and properly to
avoid air leakage.
b) Secure the cuff with the Velcro fastener, so that it lies comfortably and not too tight, whereby 2
finger space should remain between the cuff and the arm.
c) Lay the arm on a table, with the palm upwards. Support the
arm a lile with a rest (cushion), so that the cuff rests at
about the same height as the heart. Take care, that the cuff
lies free. Remain so for 2 minutes siing quietly, before
beginning with the measurement.
d) Let legs uncrossed, feet flat on the floor, back and arm
supported.
124

5.4. Measuring procedure
Aer the cuff has been appropriately positioned, the
measurement can begin:
a) Press the ON/OFF buon, the pump begins to inflate the cuff
In the display, the increasing cuff-pressure is continually
displayed.
14 15
The measurement results are displayed, until you switch the device off. If no buon is pressed for 3
minutes, the device switches automatically off, to save the baeries.
Aention
5.5. Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (e.g. the patient feels
unwell), the “ON/OFF” power buon can be pressed at any time. The device then immediately lowers
the cuff-pressure automatically.
b) Aer reaching the inflation pressure, the pump stops and the
pressure slowly falls away. The cuff-pressure is displayed
during the measurement. When the device has detected the
pulse, the heart symbol in the display begins to blink and for
every pulse beat.
The measured systolic and diastolic blood-pressure values as well
as the pulse frequency are now displayed.
Example (Fig.): Systole 126, Diastole 85, Pulse 78
5.6. Memory – storage and recall of the measurements
The blood-pressure monitor automatically stores each of the last 120 measurement values. By
pressing the MEMORY buon, an average value of the last 3 measurements as well as the last
measurement and the further last 120 measurements (MR119, MR118, …, MR1) can be displayed one
aer the other
(MR1: Values of the last measurement) (MR2-MR120: Values of the measurement before MR1)
124

5.7. Memory– cancellation of all measurements Aention!
Before you delete all readings stored in the memory, make sure you will not
need refer to the readings at a later date. Keeping a wrien record is prudent
and may provide additional information for your doctor’s visit. In order to
delete all stored readings, press the MEMORY buon for at least 5 seconds,
the display will show the symbol «CL» and then release the buon. To
permanently clear the memory, Press the MEMORY buon while «CL» is
flashing.

6. APPEARANCE OF THE HEART ARRHYTHMIA
INDICATOR FOR EARLY DETECTION
The Symbol indicates that certain pulse irregularities were detected during the measurement.
In this case, the result may deviate from your normal blood pressure – repeat the measurement. In
most cases, this is no cause for concern. However, if the symbol appears on a regular basis (e.g. several
times a week with measurements taken daily) we advise you to tell your doctor. Please show your
doctor the following explanation Information for the doctor on frequent appearance of the
Arrhythmia indicator This instrument is an oscillometric blood pressure monitor that also analyses
pulse frequency during measurement. The instrument is clinically tested. The arrhythmia symbol is
displayed aer the measurement, if pulse irregularities occur during measurement. If the symbol
appears more frequently (e.g., several times per week on measurements performed daily) we
recommend the patient to seek medical advice. The instrument does not replace a cardiac
examination but serves to detect pulse irregularities at an early stage.
7. ERROR MESSAGES /MALFUNCTIONS
If an error occurs during a measurement, the measurement is discontinued and a corresponding error
code is displayed.
Error No. Possible cause(s)
ERR 1 No pulse has been detected.
ERR 2 Unnatural pressure impulses influence the measurement result. Reason: The arm
was moved during the Measurement (Artifact).
ERR 3 The inflation of the cuff takes too long. The cuff is not correctly seated.
124
6. Aer the completion of measurement, the “Dr Trust 360 app” displays the results automatically.
7. Choose to save and share your
measurements as per your choice.

20 21
ERR 4 The measured readings indicated an unacceptable difference between systolic and
diastolic pressures. Take other reading following directions carefully. Contact you
doctor if you continue to get unusual readings.
ERR 5 Pressure in cuff is over 290mmHg
Further Information - The level of blood-pressure is subject to fluctuations even with healthy people.
Important thereby is, that comparable measurements always require the same conditions (Quiet
conditions)! If, in spite of observing all these factors, the fluctuations are larger than 15mmHg, and/or
you hear irregular pulse tones on several occasions, please consult your doctor. For licensing, the
device has been subjected to strict clinical tests, by which the computer program used to measure
the blood-pressure values was tested by experienced specialist doctors in Germany. The same
computer program is used in every individual device and has thus also been clinically tested. The
manufacture of the devices takes place according to the terms of the European standard for blood-
pressure measuring devices (see technical data) You must consult your specialist dealer or chemist if
there are technical problems with the blood-pressure instrument. Never aempt to repair the
instrument yourself!
Other possible malfunctions and their elimination
If problems occur when using the device, the following points should be checked and if necessary, the
corresponding measures are to be taken:
Malfunction Remedy
The display remains empty when the
instrument is switched on although the
baeries are in place.
1.Check baeries for correct polarity and if necessary
insert correctly.
2.If the display is unusual, re-insert baeries or
exchange them.
The device frequently fails to measure the
blood pressure values, or the values
measured are too low (too high).
1. Check the positioning of the cuff.
2. Measure the blood-pressure again in peace and
quiet under observance of the details made in the
user manual.
Every measurement produces a different
value although the instrument functions
normally and the values displayed are
normal
1. Please read the following information and the
points listed under «Common sources of error».
Repeat the measurement.
Please note: Blood pressure fluctuates continually so
successive measurements will show some variability.
Blood pressure measured differs from those
values measured by the doctor.
1. Record the daily development of the values and
consult your doctor. Please note: Individuals visiting
their doctor frequently experience anxiety which can
result in a higher reading at the doctor than obtained
at home under resting conditions.

a Field strength from fixed transmiers, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmiers, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Dr Trust BP Check Pro - 124 is used exceeds
the applicable RF compliance level above, the Dr Trust BP Check Pro - 124 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary,
b Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances:
Recommended separation distance between portable and mobile RF communications equipment
and the Dr Trust BP Check Pro - 124
The Dr Trust BP Check Pro - 124 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Dr Trust BP Check Pro - 124
can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmiers) and the Dr Trust BP Check Pro - 124 as
recommended below, according to the maximum output power of the communications equipment.
