1. Introduction
1.1. Features
The blood pressure monitor is a fully automatic, digital blood pressure measuring device for use on the
upper arm with integrated MAM and PAD technology. This monitor enables very fast and reliable
measurement of the systolic and diastolic blood pressure as well your pulse by use of the oscillometric
method.
This device is easy to use and is proven in clinical studies to provide excellent accuracy. The large display
makes it easy to visualize operational status and cuff pressure during a measurement.
Before using, please read through this instruction manual carefully and then keep it in a safe place. For
further questions on the subject of blood pressure and its measurement, please contact your doctor.
Attention!
1.2. Important information about self-measurement
•Self-measurement means Control, not diagnosis or treatment. Your values must always be discussed
with your doctor. Never alter the dosages of any medication without direction from your
doctor.
•The pulse reading is not suitable for checking heart pacemakers!
•In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only be
evaluated after consultation with the doctor.
Electromagnetic interference
The device contains sensitive electronic components. Therefore, avoid strong electrical or electromagnetic
fields in the direct vicinity of the device (e.g. mobile telephones, microwave ovens). 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?
Your blood pressure level is determined in the circulatory center of your brain. Your nervous system allows
your body to adapt or alter blood pressure in response to different situations. Your body alters your pulse
and the width of blood vessels through changes in muscles in the walls of blood vessels.
Your blood pressure reading is highest when the heart pumps or ejects blood – this is called your Systolic
Blood Pressure. Your blood pressure reading is lowest when the heart rests (in-between beats) – this is
called your Diastolic Blood Pressure.
Note: Maintain blood pressure values within a «normal» range(s) in order to prevent particular diseases.
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 140 mmHg. If you obtain readings in this range, consult your doctor immediately. High
blood pressure values over time damage blood vessels, vital organs such as the kidney and even your heart.
When blood pressure values are too low, i.e. systolic values under 100 mmHg and/or diastolic values under
60 mmHg, 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 independently alter drug
doses prescribed by your doctor.
Table for classifying blood pressure values (units mmHg): according to World Health Organization:
☞Further information
• If your values are mostly «normal» 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». In any case, please discuss the values with your doctor.
• Correctly measured diastolic blood pressure values above 120 mmHg require immediate medical
treatment.
Range Systolic
Blood Pressure
Diastolic
Blood Pressure
Measures
Hypotension lower than 100 lower than 60 Consult your doctor
Normal range between 100 and 140 between 60 and 90 Self-check
Mild hypertension between 140 and 160 between 90 and 100 Consult your doctor
Moderate hypertension between 160 and 180 between 100 and 110 Consult your doctor
Severe hypertension higher than 180 higher than 110 Consult your doctor
immediately

2.3. What can be done, if regular increased/low values are obtained?
a) Please consult your doctor.
b) Increased blood pressure values (various forms of hypertension) over time are associated with
considerable risks to health. Blood vessels in your body are endangered due to constriction caused by
deposits in the vessel walls (Arteriosclerosis). This can result in a deficient supply of blood to important
organs (heart, brain, muscles). Additionally, the heart will become structurally damaged.
c) There are many different causes of high blood pressure. We differentiate between the common primary
(essential) hypertension, and secondary hypertension. Secondary hypertension can cause organ
malfunctions. Please consult your doctor for information about the possible origins of your own
increased blood pressure values.
d) There are lifestyle changes you can make to prevent and reduce high blood pressure. These measures
must be part of a healthy lifestyle and include:
A) Eating habits
• Strive for a normal weight as prescribed by your doctor. Reduce overweight!
• Avoid excessive consumption of common salt. (Many «packaged foods» contain high levels of salt).
• Avoid fatty foods. (Packaged foods are frequently high in fats).
B) Previous illnesses
Consistently follow any medical instructions for treating previous illness such as:
• Diabetes (Diabetes mellitus or sugar diabetes)
• Fat metabolism disorder
• Gout
C) Habits
• Eliminate smoking
• Drink only moderate amounts of alcohol
• Restrict your caffeine consumption (Coffee, tea, chocolate, etc.)
D) Physical conditioning
• After a preliminary medical examination, exercise regularly.
• Choose sports which require endurance and avoid those which require strength.
• Avoid reaching the limit of your performance.
• With previous illnesses and/or an age of over 40 years, please consult your doctor before beginning your
exercise activities. Your physician will help you develop an exercise routine that is appropriate for you.
2.4. MAM technology (Microlife Average Mode)
• «MAM technology» is a new type of concept for optimum reliability in self-measurement of blood
pressure.
• An advanced measurement accuracy is achieved by the automatic analysis of three successive
measurements.
• The new system provides reliable values for the doctor and can be used as the basis for reliable
diagnostics and medication therapy for high blood pressure.
A) Why MAM?
• Human blood pressure is not stable
• Scattering of devices
4

5
B) Key advantages
Reduction of:
• Device scattering
• Insufficient rest prior to measurement
• Movement artefacts
• Cuff positioning influences
C) Medical benefits
• Improved accuracy
• Reliable patient self-measurement data for the doctor
• Safe hypertension diagnostic
• Reliable therapy control
D) Measurement sequence
• With the full measurement cycles, the total measurement time remains less than 3 minutes, compared
to a single measurement time of 1.5 minute.
• Single results are not displayed.
• Due to the «Data Analysis» result, a 4th measurement may be applied.
2.5. PAD - Pulse Arrhythmia Detection
Appearance of the Arrhythmia indicator
The appearance of this symbol signifies that a certain pulse irregularity was detected during the
measurement. The result can vary from your normal blood pressure. 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.
Please show your doctor the following explanation:
Information for the doctor on frequent appearance of the Arrhythmia indicator
This device is an oscillometric blood pressure measuring device that also analyses the pulse
frequency during measurement. The accuracy of this device has been clinically validated.
If pulse irregularities occur during measurement, the arrhythmia symbol is displayed after the
measurement. 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 the patient to seek medical advice.
The device does not replace a cardiac examination, but serves to detect pulse irregularities at an
early stage.

5. Carrying out a Measurement
5.1. Before the measurement
• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these
factors influence the measurement result. Try to find time to relax by sitting in an armchair in a quiet
atmosphere for about 5 minutes before measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Take measurements regularly at the same time of day, since blood pressure changes during the course
of the day.
5.2. Common sources of error
Note: Comparable blood pressure measurements always require the same conditions!
These are normally always quiet conditions.
• All efforts by the patient to support their arm can increase 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.
• If the arm artery lies considerably lower (higher) than the heart, an false reading will be obtained. Each
15 cm difference in height results in a measurement error of 10 mmHg!
• Cuffs that are too narrow or too short result in false measurement values. Selecting the correct cuff is
of extraordinary importance. The cuff size is dependent upon the circumference of the arm (measured in
the center). The permissible range is printed on the cuff. If this is not suitable for your use, please
contact your dealer.
Note: Only use clinically approved Microlife Cuffs!
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after a 1 minute pause or after the arm
has been held up in order to allow the accumulated blood to flow away.
5.3. Fitting the cuff
a) Push the cuff over the left upper arm so that the tube points in
the direction of the lower arm.
b) Lay the cuff on the arm as illustrated. Make certain that the
lower edge of the cuff lies approximately 2 to 3 cm above the
elbow and that the rubber tube leaves the cuff on the inner side
of the arm.
c) Tighten the free end of the cuff and close the cuff with the
Velcro.
d) The cuff should be snug on your upper arm, but not too tight. Any
clothing which restricts the arm (e.g. pullover) must be taken off.
e) Lay your arm on a table (palm upwards) so that the cuff is at the
same height as the heart. Make sure that the tube is not kinked.
2–3 cm

Note:
If it is not possible to fit the cuff to the left arm, it can also be
placed on the right. However all measurements should be made
using the same arm.
5.4. Measurement mode selection
Clinical studies demonstrate taking multiple blood pressure readings and calculating an «average» is more
likely to determine your true blood pressure. This blood pressure monitor allows you to switch to the special
Microlife Average Mode – MAM – that automatically takes multiple readings!
MAM Mode:
a) If you would like to take a MAM measurement, please slide the
switch to the right toward no. 3.
b) MAM mode takes generally 3 measurements in succession and
calculates the result.
c) The « » symbol in the display indicates that the device is
set to the MAM mode.
Single mode:
a) If you would like to take single measurement, please slide the
switch toward no. 1.
b) Single mode only has 1 measurement.
5.5. Measuring procedure
After the cuff has been appropriately positioned, the measurement can begin:
a) Press the O/I button. The pump begins to inflate the cuff. The
rising pressure in the cuff is shown in the display.
b) After reaching the inflation pressure, the pump stops and the
pressure gradually falls. The cuff pressures are displayed. In
case that the inflation pressure is not sufficient, the monitor
automatically re-inflates to a higher level.
c) When the instrument detects a pulse, the heart symbol in the
display starts to flash and a beep is heard for every heartbeat.
d) A longer beep is sounded when the measurement has been
completed. The systolic, and diastolic blood pressures and pulse
rate now appear in the display.
e) The measurement results are displayed, until you switch the
device off. If no button is pressed for 5 minutes, the device
switches automatically off, to save the batteries.
f) When the device is set to MAM mode, generally 3 separate
measurements will take place in succession and calculates your
13

TIME

detected blood pressure value. There will be 15 seconds resting time
in-between each measurement. A count down indicates the remaining
time and a beep will sound 5 seconds before the 2nd and 3rd readings
will begin. In case that the single data of each cycle differ too much
from each other, a fourth measurement is performed before the result
will be displayed. In rare cases the blood pressure is such unstable
that even after four measurements the data vary too much. In this
case «ERR 6» is shown and no result can be given.
If one of measurement causes an error message it is repeated.
5.6. Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any
reason (e.g. the patient feels unwell), the 0/I button can be pressed
at any time.
The device immediately lowers the cuff pressure automatically.
5.7. Memory – recall of measurements
This device automatically stores the last 99 measurements. By
pressing the MEMORY button, the number of stored measurements
is displayed (e.g. 30 set). By pressing again, the last measurement,
e.g. MR30 as well as previous 29 measurements (MR29, MR28,
…MR1) can be displayed one after the other. Data obtained in
MAM mode are indicated by a « » symbol.
30 sets of stored measurements – MR30: Value of the last measurement – MR29: Value of the measurement before MR 30
5.8.Memory– cancellation of all measurements
Attention!
Before you delete all readings stored in the memory, make sure you
will not need refer to the readings at a later date.
In order to delete all stored readings, depress the MEMORY button for
at least 7 seconds, the display will show the symbol «CL» and 3 short
beep sounds will be heard to indicate deletion of stored readings.
Note:
If your last stored measurement was taken in the MAM mode, you
will see the « » symbol approximately 3 seconds during the
deletion procedure. (The display will show this symbol during
deletion of all stored measurements, if the last measurement is
taken in the MAM mode).
