1. Introduction
1.1.Features of your Microlife Premium Portable Automatic Blood Pressure
Monitor
Your Microlife blood pressure monitor with Microlife Averaging Mode and Irregular
Heartbeat Detection is a fully automatic digital blood pressure measuring device for use
by adults on the upper arm at home or in your doctor’s/nurse’s office. It enables very fast
and reliable measurement of systolic and diastolic blood pressure as well as pulse by way
of the oscillometric method. This device offers clinically proven accuracy and has been
designed to be portable and very user friendly.
Before using, please read this instruction manual carefully and then keep it in a safe
place. Please contact your doctor for further questions on the subject of blood pressure
and its measurement.
Attention!
1.2.Important information about self-measurement
• 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.
•The pulse display is not suitable for checking the frequency of heart pacemakers!
•In cases of irregular heartbeat (Arrhythmia), measurements made with this instrument
should only be evaluated after consultation with your doctor.
Electromagnetic interference:
The device contains sensitive electronic components. Avoid strong electrical or electro-
magnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave
ovens). These can lead to temporaryimpairment of the measuring accuracy.
2. Important information on blood pressure and its measurement
2.1. How does high/low blood pressure arise?
Your level of blood pressure is determined in the circulatory center of the brain and
adjusts to a variety of situations through feedback from the nervous system. To adjust
blood pressure, the strength and frequency of the heart (Pulse), as well as the width of cir-
culatory blood vessels is altered. Blood vessel width is affected by fine muscles in the
blood vessel walls.
Your level of arterial blood pressure changes periodically during heart activity: During the
“blood ejection” (Systole) the value is highest (systolic blood pressure value). At the end
of the heart’s “rest period” (Diastole) pressure is lowest (diastolic blood pressure value).
Blood pressure values must lie within certain normal ranges in order to prevent particular
diseases. 3

4
2.2. Which values are normal?
Blood pressure is very high if your diastolic pressure is above 90 mmHg and/or your
systolic blood pressure is over 160 mmHg, while at rest.In this case, please con-
sult your physician immediately. Long-term values at this level endanger your health
due to continual damage to the blood vessels in you body.
If your systolic blood pressure values are between 140 mmHg and 159mmHg and/or
the diastolic blood pressure values between 90 mmHg and 99mmHg, consult your
physician. Regular self-checks are necessary.
If you have blood pressure values that are too low, (i.e., systolic values under
105mmHg and/or diastolic values under 60 mmHg), consult your physician.
Even with normal blood pressure values, a regular self-check with your blood pres-
sure monitor is recommended. You can detect possible changes in your values early
and react appropriately.
If you are undergoing medical treatment to control your blood pressure, keep a
recordof values along with time of day and date. Show these values to your physi-
cian. Never use the results of your measurements to independently alter the
drug doses prescribed by your physician.
Which values are normal?
The following standards for assessing high blood pressure (without regard to age)
have been established by the National Institutes of Health JNCV7, 2003.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 <80
Pre-Hypertension 120-139 80-89
Hypertension
Stage 1 Hypertension 140-159 90-99
Stage 2 Hypertension >160 >100

5
☞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.” Consult your doctor.
•Correctly measured diastolic blood pressure values above 120mmHg require
immediate medical treatment.
2.3. What can be done if regular high or low values are obtained?
a) Consult your doctor.
b) Increased blood pressure values (various forms of hypertension) are associated with
considerable health risks over time. Arterial blood vessels in your body are endangered
due to constriction caused by deposits in the vessel walls (Arteriosclerosis). A deficient
supply of blood to important organs (heart, brain, muscles) can result from arterioscle-
rosis. Furthermore, the heart will become structurally damaged with increased blood
pressure values.
c) There are many different causes of high blood pressure. We differentiate between the
common primary (essential) hypertension, and secondary hypertension. The latter
group can be ascribed to specific organ malfunctions. Please consult your doctor for
information about the possible origins of your own increased blood pressure values.
d) There are measures which you can take to reduce and even prevent high blood pres-
sure. These measures must be permanent lifestyle changes.
A) Eating habits
• Strive for a normal weight corresponding to your age. See your doctor for your ideal
weight.
• Avoid excessive consumption of common salt.
• Avoid fatty foods.
B) Previous illnesses
•Consistently follow all medical instructions for treating illness such as:
•Diabetes (Diabetes mellitus or sugar diabetes)
•Fat metabolism disorder
•Gout
C) Habits
• Give up smoking completely.
• Drink only moderate amounts of alcohol.
•Restrict your caffeine consumption (coffee, tea, chocolate).

6
D) Your physical condition
•After a medical examination, and with your doctor’s approval and direction,
exercise.
• Choose sports which require stamina 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 routine. You must receive advice regarding the type and
extent of exercise that is appropriate for you.

4.7. Microlife Averaging Mode
In Microlife Averaging Mode, three measurements are auto-
matically taken in succession and the result then automatical-
ly analyzed and displayed. Because your blood pressure con-
stantly fluctuates, a result determined in this way is more reli-
able than one produced by a single measurement.
The switch on the side of the blood pressure monitor (right
above the Time/Date button but below the AC Adapter con-
nection port [AC Adapter sold separately]) allows you to select
whether you want to take a single measurement or three con-
secutive measurements in Microlife Averaging Mode. If you
slide the switch toward the 3, the unit is in averaging mode.
The resulting measurement on the display will indicate that
the measurement is from Microlife Averaging Mode because
an icon will appear when a measurement was taken
in this mode.
After pressing the START/STOP button the selected Microlife
Averaging Mode appears in the display as the symbol.
Single Mode: If you want a single measurement then slide
the switch towardthe 1 on the side of the unit. The single
measurement will take just a single reading.

5. Measurement Procedure
Please note: You should always be seated before and during measurement.
5.1. Before measurement:
• Avoid eating and smoking as well as all forms of exertion directly before meas-
urement. These factors influence the measurement result. Find time to relax by
sitting in an armchair in a quiet atmosphere for about ten minutes before meas-
urement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Always compare measurements taken at the same time of day, since blood pres-
sure changes during the course of the day.
5.2. Common sources of error:
Note: Comparable blood pressure measurements always require the same
conditions! Conditions should always be quiet.
•All efforts by the user to support the arm can increase blood pressure. Make sure
you are in a comfortable, relaxed position and do not flex 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 or higher than the heart, an erroneously
high or low blood pressure will be measured! Each 15cm (6 inch) difference in
height between your heart and the cuff results in a measurement error of 10
mmHg!
•Cuffs that aretoo narrow or too shortresult in false measurement values.
Selecting the correct cuff is extremely important. Cuff size is dependent upon the
circumference of the arm (measured in the center). The permissible range is print-
ed on the cuff. If this is not suitable for your use, please call 1-800-568-4147.
Note: Only use clinically approved 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
a1minute pause or after your arm has been held up in order to allow the accumu-
lated blood to flow away.

5.3. Fitting the cuff
a) Pass the end of the cuff through the flat
metal ring so that a loop is formed. The
Velcro™ closer must be facing outward.
(Ignore this step if the cuff has already been
prepared.)
b) Place the cuff over the left upper arm so that
the tube is closer to your lower arm.
c) Lay the cuff on the arm as illustrated. Make
certain that the lower edge of the cuff lies
approximately 3/4” to 1”(2 to 3cm) above the
elbow and that the tube is closer to the inner
side of the arm.
Important! The small white arrow (Artery
Mark) on the cuff must lie exactly over the
artery which runs down the inner side of the
arm.
d) Tighten the cuff by pulling the end and close
the cuff by affixing the Velcro™.
e) There should be little free space between the
armand the cuff. You should able to fit 2 fin-
gers between your arm and the cuff. Clothing
must not restrict the arm. Any piece of cloth-
ing which does must be removed. Cuffs that
don’tfit properly result in false measurement
values. Measure your arm circumference if
you arenot sureof proper fit. Larger cuffs are
available (Section 3B).
f) Lay your arm on a table (palm upward) so the
cuffis at the same height as your heart.
Make sure the tube is not kinked.
g) Remain seated quietly for at least two
minutes beforeyou begin the measurement.

Comment:
If it is not possible to fit the cuff to your left arm, it can also be
placed on your right arm. However, all measurements should be
made using the same arm.
Comparable blood pressure measurements always require the
same conditions (Relax for several minutes before a reading).
5.4. Measuring procedure
After the cuff has been appropriately positioned on the
arm and connected to the blood pressure monitor the
measurement can begin:
a) Press the START/STOP button. The pump
begins to inflate the cuff. In the display, the
increasing cuff pressure is continually displayed.
b) After automatically reaching an individual pressure,
the pump stops and the pressure slowly falls. The cuff
pressure is displayed during the measurement.
c) When the device has detected your pulse, the heart
symbol in the display begins to blink.
d) When the measurement has been concluded, a long
beep tone sounds. The measured systolic and diastolic
blood pressurevalues, as well as the pulse are now
displayed.
e) The appearance of this symbol signifies that an
irregular heartbeat was detected. This indicator is only
acaution. It is important that you be relaxed, remain
still and do not talk during measurements. NOTE: We
recommend contacting your physician if you see this
indicator frequently.
f) The measurement results are displayed until you
switch the device off. If no button is pressed for 1
minute, the device switches offautomatically.
g) You can take a measurement while holding this moni-
tor in your hand if you do not want or have a hard sur-
face to place the unit on. However, you should always
hold the unit in the opposite arm of the cuff. If the cuff
is on the left arm, hold the blood pressure monitor in
your right hand.

When the unit is set to the Averaging Mode setting, 3 separate measurements
will take place in succession after which your result is calculated. There is a 15
second 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 read-
ings will begin.
If one of the measurements causes an error message, it will be repeated one more time.
If any additional error occurs, the measurements will be discontinued and an error code
displayed.
Expanding the averaged measurement to see the three individual readings:
This function allows you to view the three individual measurements used to calculate the
Microlife Averaging Mode (MAM) measurement. After taking a MAM measurement hold
the memorybutton for 3 seconds until you hear a short beep. (Do not hold the button
longer than 7 seconds or you will delete all the readings in the memory.) Let go of the but-
ton and watch the screen. It will automatically scroll through the
three measurements used in the measurement.
5.5. Irregular Hearbeat Detector
This symbol indicates that certain pulse irregularities were
detected during the measurement. In this case, the result may
deviate from your normal basal blood pressure – repeat the meas-
urement. 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 Irregular Heartbeat Symbol
This instrument is an oscillometric blood pressure monitor device that also analyzes pulse
frequency during measurement. The instrument is clinically tested.
If pulse irregularities occur during measurement, the irregular heartbeat symbol is dis-
played after the measurement. If the symbol appears morefrequently (e.g. several times
per week on measurements performed daily) or if it suddenly appears moreoften than
usual, we recommend the patient to seek medical advice.
The instrument does not replace a cardiac examination, but serves to detect pulse irregu-
larities at an early stage.

16
5.6. Memory – displaying the last 99 measurements
At the end of a measurement, this monitor automatically stores each result with date and
time. This unit stores 99 memories for each of 2 users.
Viewing the stored values
With the unit off, press the "M" button. The display first shows "A", then shows an aver-
age of all measurements stored in the unit. Please note: measurements for each user
are averaged and stored separately, be certain that you are viewing the meas-
urements for the correct user.
Pressing the "M" button again displays the previous value. To view a particular stored
memory, press and hold the “M” button to scroll to that stored reading.
Memory full
When the memory has stored 99 results a new measured value is stored by overwriting
the oldest value.
Clear all values
If you are sure that you want to permanently remove all stored values, hold down the "M"
button (the instrument must have been switched off beforehand) until "CL" appears and
then release the button. If you do not want to clear the values, press the On/off button. To
permanently clear the memory, press the "M" button while "CL" is flashing.
Individual values cannot be cleared.
5.7. Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any rea-
son (e.g the patient feels unwell), the START/STOP button can be
pressed at any time. The device then immediately lowers the cuff pres-
sure automatically.

17
5.8. Battery Charge Indicator
Batteries almost discharged
When the batteries are approximately 75% used the battery symbol
will flash as soon as the instrument is switched on (if at least one of
the batteries still has some charge). Although the instrument will con-
tinue to measure reliably, you should obtain replacement batteries.
Batteries discharged– replacements required
When the batteries are discharged, the battery symbol will flash as
soon as the instrument is switched on. You cannot take any further
measurements and must replace the batteries.
1. Open the battery compartment at the back of the instrument by pushing inwards at
the arrow and pulling it out.
2. Replace the batteries – ensure they are correctly connected, as shown on the symbols
in the compartment.
3. The memory retains all values although date and time (and possibly also set alarm
times) must be reset - the year number therefore flashes automatically after the bat-
teries are replaced.
4. To set date and time, follow the procedure described in Section 4.2.
Which batteries and which procedure?
Use four new, longlife 1.5V AA batteries. Do not use batteries beyond their expiration
date. If the monitor is not going to be used for a prolonged period the batteries should
be removed.
Using rechargeable batteries
You can also operate this instrument using rechargeable batteries.
•Please use only type "NiMH" reusable batteries!
•If the batterysymbol ( ) appears, the batteries must be removed and
recharged! They must not remain inside the instrument, as they may become dam-
aged through total discharge even when switched off. The batteries must NOT be dis-
charged in the blood pressuremonitor! If you do not intend to use the instrument for a
week or more, always remove the rechargeable batteries!
•Recharge these batteries in an external charger and follow manufacturer’s instructions
carefully.

6. Error Messages/Troubleshooting
If an error occurs during a measurement, the measurement is discontinued
and a corresponding error code is displayed. We recommend you switch the
device off and take a new measurement making sure you allow time for
relaxation. (example: error no. 1)
Repeat measurement keeping arm still.
If inflation of the cuff takes too long, the
cuff is not correctly seated or the hose
connection is not tight.
Check connections and repeat.
The difference between systolic and dias-
tolic is excessive. Measure again carefully
following proper cuff procedures and
ensure measurement under quiet condi-
tions.
Error No. Possible cause(s) / Solutions
ERR 1 The tube may have loosened, or no pulse
was detected.
*Ensure cuff connections are tight with
proper cuff placement. See section (5.3)
ERR 2 Unnatural pressure impulses. Reason:
The arm was moved during the
measurement (referred to as an artifact).
Repeat measurement keeping arm still.
ERR 3
ERR 5
The cuff pressure is too high. Relax for 5
minutes and repeat the measurement.*
HI
The pulse is too low (less than 40).
Repeat the measurement.*
LO
*If this or any other problem occurs repeatedly,please consult your doctor.

19
Other possible errors and their solutions
If problems occur when using the device, the following points should be checked:
Malfunction Remedy
•Check battery installation.
•If the display is unusual, remove the batteries
and then exchange them for new ones.
Check polarity.
•Check the connection of the cuff tube and
connect properly.
1. Fit the cuff correctly on the arm. (see 5.3)
2. Before starting measurement make sure
that the cuff is not too tight and that clothing
is not exerting pressure on the arm. Take
articles of clothing off if necessary.
3. Measure blood pressure again in complete
peace and quiet.
•Please read the following information and
the points listed under “Common sources of
error”.(5.2) Repeat the measurement.
•Blood pressure changes constantly. The
observed readings may accurately reflect
your pressure.
•Recorddaily values and consult your doctor.
•Pressure readings in your doctor’s office may
be higher due to anxiety.
•Check cuff connections.
Ensure the unit has not been tampered with.
The display remains blank when the instrument
is switched on although the batteries are in
place.
The pressure does not rise although the pump
is running.
The device frequently fails to measure,
or the values measured are too low or high.
Every measurement results in different values,
although the device functions normally and
normal values are displayed.
Blood pressure values differ from those meas-
ured by my doctor
After the instrument has inflated the cuffthe
pressure falls very slowly, or not at all. (No rea-
sonable measurement possible).

20
7. Care and maintenance
a) Do not expose the device to either extreme
temperatures, humidity, dust or direct sun-
light.
b) The cuff contains a sensitive air-tight bubble.
Handle this cuff carefully and avoid all types
of stress through twisting or buckling.
c) Clean the device with a soft, dry cloth. Do not
use gas, thinners or similar solvents. Spots
on the cuff can be removed carefully with a
damp cloth and soapsuds. The cuff with
bladder must not be washed in a dish-
washer,clothes washer, or submerged
in water.
d) Handle the tube carefully. Do not pull on it.
Do not allow the tubing to kink and keep it
away from sharp edges.
e) Do not drop the monitor or treat it roughly in
any way.Avoid strong vibrations.
f) Never open the monitor! This invalidates
the manufacturer’swarranty.
g) Batteries and electronic instruments must be
disposed of in accordance with the locally
applicable regulations, not with domestic
waste.
