1. Introduction
1.1. Features of your Automatic Blood Pressure Monitor
Your blood pressure monitor with Mi rolife Averaging Mode, Irregular Heartbeat
Dete tion, and PC Link Blood Pressure Analyzer Software is a fully automati digital
blood pressure measuring devi e for use by adults on the upper arm at home or in
your do tor’s/nurse’s offi e. It enables very fast and reliable measurement of systoli
and diastoli blood pressure as well as pulse through the os illometri method. This
devi e offers lini ally proven a ura y and has been designed to be user friendly.
Before using, please read this instru tion manual arefully and then keep it in a safe
pla e. Please onta t your do tor for further questions on the subje t of blood pres-
sure and its measurement.
Attention!
1.2. Important information about self-measurement
• Self-measurement means control, not diagnosis or treatment. Unusual values
must always be dis ussed with your do tor. Under no circumstances should
you alter the dosages of any drugs prescribed by your doctor.
•The pulse display is not suitable for he king the frequen y of heart pa emakers!
•In ases of irregular heartbeat, measurements made with this instrument should
only be evaluated after onsultation with your do tor.
Electromagnetic interference:
The devi e ontains sensitive ele troni omponents. Avoid strong ele tri al or ele -
tromagneti fields in the dire t vi inity of the devi e (e.g. mobile telephones,
mi rowave ovens). These an lead to temporary impairment of the measuring a ura y.
2. Important Information on Blood Pressure and its Measurement
2.1. How does high or low blood pressure arise?
Your level of blood pressure is determined in the ir ulatory enter of the brain and
adjusts to a variety of situations through feedba k from the nervous system. To adjust
blood pressure, the strength and speed of the heart (Pulse), as well as the width of
ir ulatory blood vessels is altered. Blood vessel width is ontrolled by fine mus les
in the blood vessel walls.
Your level of arterial blood pressure hanges periodi ally during heart a tivity: During
the “blood eje tion” (Systole) the value is highest (systoli blood pressure value). At
the end of the heart’s “rest period” (Diastole) pressure is lowest (diastoli blood pres-
sure value).

3
Blood pressure values must lie within ertain normal ranges in order to prevent par-
ti ular diseases.
2.2. Which values are normal?
Blood pressure is very high if your diastoli pressure is above 100 mmHg and/or
your systoli blood pressure is over 160 mmHg, while at rest. In this ase,
please onsult your physi ian immediately. Long-term values at this level endan-
ger your health due to ontinual damage to the blood vessels in your body.
If your systoli blood pressure values are between 140 mmHg and 159mmHg
and/or the diastoli blood pressure values between 90 mmHg and 99mmHg,
onsult your physi ian. Regular self- he ks are ne essary.
If you have blood pressure values that are too low, (i.e., systoli values under
105mmHg and/or diastoli values under 60 mmHg), onsult your physi ian.
Even with normal blood pressure values, a regular self- he k with your blood
pressure monitor is re ommended. You an dete t possible hanges in your val-
ues early and rea t appropriately.
If you are undergoing medi al treatment to ontrol your blood pressure, keep a
re ord of values along with time of day and date. Show these values to your
physi ian. 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 in adults have been
established by the U.S. National Institutes of Health JNC7, 2003.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 and <80
Pre-Hypertension 120-139 or 80-89
Hypertension
Stage 1 Hypertension 140-159 or 90-99
Stage 2 Hypertension ≥160 or ≥100

+Further information
• If your values are mostly normal under resting onditions but ex eptionally high
under onditions of physi al or psy hologi al stress, it is possible that you are
suffering from so- alled “labile hypertension.” Consult your do tor.
•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 do tor.
b) In reased blood pressure values (various forms of hypertension) are asso iated
with onsiderable health risks over time. Arterial blood vessels in your body are
endangered due to onstri tion aused by deposits in the vessel walls
(Arterios lerosis). A defi ient supply of blood to important organs (heart, brain,
mus les) an result from arterios lerosis. Furthermore, the heart will be ome
stru turally damaged with in reased blood pressure values.
) There are many different auses of high blood pressure. We differentiate
between the ommon primary (essential) hypertension, and se ondary hyperten-
sion. The latter group an be as ribed to spe ifi organ malfun tions. Please on-
sult your do tor for information about the possible origins of your own in reased
blood pressure values.
d) There are measures whi h you an take to redu e and even prevent high blood
pressure. These measures must be permanent lifestyle hanges.
A) Eating habits
• Strive for a normal weight orresponding to your age. See your do tor for your
ideal weight.
• Avoid ex essive onsumption of ommon salt.
• Avoid fatty foods.
B) Previous illnesses
• Consistently follow all medi al instru tions for treating illness su h as:
• Diabetes (Diabetes mellitus or sugar diabetes)
• Fat metabolism disorder
• Gout
C) Habits
• Give up smoking ompletely.
• Drink only moderate amounts of al ohol.
• Restri t your affeine onsumption ( offee, tea, ho olate).

D) Your physical condition
• After a medical examination, and with your doctor’s approval and
direction; exercise.
• Choose sports whi h require stamina and avoid those whi h require strength.
• Avoid rea hing the limit of your performan e.
• With previous illnesses and/or an age of over 40 years, please onsult
your do tor before beginning your exer ise routine. Speak with your do tor
regarding the type and extent of exer ise that is appropriate for you.

4.3. Cuff tube connection
Insert the uff tube into the opening on
the side of the monitor indi ated by the
drawing of a uff.
4.4. Cuff holder attachment
Atta h the uff holder to the bottom of the
monitor by inserting the tabs into the slots provided.
4.5. Select the Measuring Mode: Standard or
Microlife Averaging Mode
This instrument enables you to sele t either standard (single
measurement) or Mi rolife Averaging Mode (automati triple
measurement). To sele t standard mode, push the swit h on
the side of the instrument downward to Position "1“ and to
sele t Averaging mode, upwards to Position “3”. If you sele t
1 then only one measurement will be taken. If you sele t 3,
the unit will inflate and deflate three times resulting in one
final average measurement.
4.6. Select the User
This blood pressure monitor is designed to store 120 meas-
urements for ea h of two users. In addition, there is a guest
mode in whi h results are not stored. Before taking a meas-
urement, be ertain that the orre t user has been sele ted.
a) With the unit off, press and release the TIME button to
y le through users (“1,”2,”or guest mode).
b) Press the START button to make your sele tion.
4.6. Microlife Averaging Mode Technology
• In Mi rolife Averaging Mode, three measurements are auto mati ally taken in su -
ession and the result then automati ally analyzed and displayed. Be ause your
blood pressure onstantly flu tuates, a result determined in this way is more reliable
than one produ ed by a single measurement.
• After pressing the Start/Stop button the sele ted Mi rolife Averaging Mode
appears in the display as the symbol.
• The bottom, right hand se tion of the display shows a 1, 2 or 3 to indi ate whi h of
the 3 measurements is urrently being taken.

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 dire tly before
measurement. These fa tors influen e the measurement result. Find time to
relax by sitting in an arm hair in a quiet atmosphere for about ten minutes
before taking a measurement.
• Remove any garment that fits losely to your upper arm.
• Always measure on the same arm (normally left).
• Always ompare measurements taken at the same time of day, sin e blood
pressure hanges during the ourse of the day, as mu h as 20-40 mmHg.
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 an in rease blood pressure. Make
sure you are in a omfortable, relaxed position and do not flex any of the
mus les in the measurement arm during the measurement. Use a ushion for
support if ne essary.
• If the arm artery lies onsiderably lower or higher than the heart, an erro-
neously high or low blood pressure will be measured! Ea h 15 m (6 in h) dif-
feren e in height between your heart and the uff results in a measurement
error of 10 mmHg!
• Cuffs that are too narrow or too short result in false measurement values.
Sele ting the orre t uff is extremely important. Cuff size is dependent upon
the ir umferen e of the arm (measured in the enter). The permissible range
is printed on the uff. If this is not suitable for your use, please all 1-800-
568-4147.
Note: Only use clinically approved Microlife cuffs!
•
A loose uff or a sideways protruding air po ket auses false measurement values.
• With repeated measurements, blood a umulates in the arm, whi h an lead
to false results. Conse utive blood pressure measurements should be repeat-
ed after a 1 minute pause or after your arm has been held up in order to allow
the a umulated blood to flow away.
If you de ide to take your Averaging Mode measurement again, be sure to
wait at least one minute beforehand.

5.3. Fitting the Cuff
a) The uff is pre-formed for easier use.
Remove tight or bulky lothing from your
upper arm.
b) Wrap the uff around your upper left
arm. The rubber tube should be on the
inside of your arm extending downward
to your hand. Make ertain the uff lies
approximately 1/2” to 3/4” (1 to 2 m)
above the elbow.
Important! The red strip on the edge of
the uff (Artery Mark) must lie over the
artery whi h runs down the inner side of
the arm.
TIP: Align red artery mark to pinky finger.
) To se ure the uff, wrap it around your
arm and press the vel ro together.
d) There should be little free spa e
between the arm and the uff. You
should able to fit 2 fingers between your
arm and the uff. Clothing must not
restri t the arm. Any pie e of lothing
whi h does, must be removed. Cuffs
that don’t fit properly result in false
measurement values. Measure your arm
ir umferen e if you are not sure of
proper fit.
e) Lay your arm on a table (palm upward)
so the uff is at the same height as your
heart. Make sure the tube is not kinked.
f) Remain seated quietly for at least two
minutes before you begin the measure-
ment.

8.7” - 16.5”

Comment:
If it is not possible to fit the uff to your left arm, it an
also be pla ed on your right arm. However, all measure-
ments should be made using the same arm.
Comparable blood pressure measurements always
require the same onditions (Relax for several minutes
before taking a measurement).
5.4. Measuring procedure
After the uff has been appropriately positioned on the
arm and onne ted to the blood pressure monitor, the
measurement an begin:
a) Press the START/STOP button. The pump
begins to inflate the uff. In the display, the
in reasing uff pressure is ontinually displayed.
b) After automati ally rea hing an individual pressure,
the pump stops and the pressure slowly falls. The
uff pressure is displayed during the measurement.
) When the devi e has dete ted your pulse, the heart
symbol in the display begins to blink.
d) When the measurement has been on luded, a long
beep tone sounds. The measured systoli and dias-
toli blood pressure values, as well as the pulse are
now displayed.
e) The appearan e of this symbol signifies that an
irregular heartbeat was dete ted. This indi ator is
only a aution. It is important that you be relaxed,
remain still and do not talk during measurements.
NOTE: We re ommend onta ting your physi ian if
you see this indi ator frequently.
f) The measurement results are displayed until you
swit h the devi e off. If no button is pressed for 1
minute, the devi e swit hes off automati ally.

5.5. Irregular Heartbeat Detector
This symbol indi ates that ertain pulse irregulari-
ties were dete ted during the measurement. In this
ase, the result may deviate from your normal basal
blood pressure – repeat the measurement. In most
ases, this is no ause for on ern. However, if the sym-
bol appears on a regular basis (e.g. several times a
week with measurements taken daily), we advise you to
tell your do tor. Please show your do tor the following
explanation:
Information for the doctor on frequent appearance of the Irregular
Heartbeat Symbol
This instrument is an os illometri blood pressure monitor devi e that also ana-
lyzes pulse frequen y during measurement. The instrument is lini ally tested.
If pulse irregularities o ur during measurement, the irregular heartbeat 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 re ommend the patient to seek medi al
advi e.
The instrument does not repla e a ardia examination, but serves to dete t
pulse irregularities at an early stage.

5.6. Traffic Light Indicator
The bars on the left-hand edge of the display show you the range within whi h
the indi ated blood pressure value lies. Depending on the height of the bar, the
readout value is either within the normal (green), borderline (yellow) or danger
(orange) range.
The lassifi ation is based on standards established by the National Institutes
of Health JNC7, 2003.
Refer to the hart in se tion 2.2 of this instru tion manual for details of the lassifi ations.
The traffi light bar raises a ording to your measurement.
• If your measurement has 1-2 bars, your measurement is in the green zone, or
“Normal” a ording to NIH standards.
• If your measurement has three bars, it is in the yellow zone, or “Pre-Hypertension”
a ording to NIH standards.
• If your measurement has four bars, it is in the light orange “Stage 1 Hypertension”
zone.
• If your measurement has 5-6 bars, it is in the dark orange “Stage 2 Hypertension”
zone.

5.7. Memory – Displaying the last 120 Measurements
At the end of a measurement, this monitor automati ally stores ea h result with date
and time. This unit stores 120 memories for ea h of 2 users.
Viewing the stored values
With the unit off, press the "M" button. The display first shows "A", then shows an
average of all measurements stored in the unit. Please note: Measurements for
each user are averaged and stored separately. Be certain that you are view
ing the measurements for the correct user.
Pressing the "M" button again displays the previous value. To view a parti ular stored
memory, press and hold the “M” button to s roll to that stored reading.
Memory full
When the memory has stored 120 results a new measured value is stored by over-
writing the oldest value.
Clear all values
If you are sure that you want to permanently remove all stored val-
ues, hold down the "M" button (the instrument must have been
swit hed off beforehand) until "CL" appears and then release the
button. If you do not want to lear the values, press the
START/STOP button. To permanently lear the memory, press the
"M" button while "CL" is flashing.
Individual values annot be leared.
5.8. Discontinuing a Measurement
If it is ne essary to interrupt a blood pressure measurement for any
reason (e.g the patient feels unwell), the START/STOP button an
be pressed at any time. The devi e then immediately lowers the
uff pressure automati ally.

5.9. Setting the Medication Reminder
This instrument allows you to set two alarm times at whi h an alarm signal will then
be triggered. This an be a useful aid, for instan e as a reminder to take medi ation
or to remind you to take your blood pressure at the same time ea h day.
1. To set an alarm time, press the time button (the
instrument must have been swit hed off beforehand)
and immediately afterwards the "M" button and hold
both down until the bell symbol appears in the bot-
tom left of the display. Then release both buttons.
The flashing "1" in the display indi ates that the first
alarm time an now be set.
2. Press the time button to set the hours – the hours
display flashes and pressing the "M" button allows
you to set the alarm hour. To onfirm, press the time
button.
3. The minute display will now flash. The minutes an
be set using the "M" button. To onfirm, press the
time button again.
4. The bell symbol will now flash. Use the "M" button to
sele t whether the alarm time is to be a tive (bell) or
ina tive ( rossed-out bell). To onfirm, press the time
button.
To set a second alarm time, proceed as above but
if the "1" flashes, press the "M" button to select "2"
and confirm with the time button.
• An a tive alarm time is indi ated by the bell symbol
in the display.
• The alarm sounds at the set time every day.
• To swit h-off the alarm when it is sounding, press the
START/STOP button.
• To permanently swit h-off the alarm, pro eed as
above (steps 1-4) and sele t the rossed-out bell sym-
bol. This will then disappear from the display.
• The alarm times must be re-entered ea h time the
batteries are repla ed.

5.10. Battery Charge Indicator
Batteries almost discharged
When the batteries are approximately 75% used the battery
symbol will flash as soon as the instrument is swit hed on
(if at least one of the batteries still has some harge).
Although the instrument will ontinue to measure reliably,
you should obtain repla ement batteries.
Batteries discharged– replacements required
When the batteries are dis harged, the battery symbol will
flash as soon as the instrument is swit hed on. You annot
take any further measurements and must repla e the batter-
ies.
1. Open the battery ompartment at the ba k of the instrument by pushing
inward at the two arrows and pulling it out.
2. Repla e the batteries – ensure they are orre tly onne ted, as shown on the
symbols in the ompartment.
3. The memory retains all values although date and time (and possibly also set
alarm times) must be reset - the year number therefore flashes automati ally
after the batteries are repla ed.
4. To set date and time, follow the pro edure des ribed in Se tion 4.2.
Which batteries and which procedure?
Use four new, longlife 1.5V AA batteries. Do not use batteries beyond their expi-
ration date. If the monitor is not going to be used for a prolonged period the bat-
teries should be removed.
Using rechargeable batteries
You an also operate this instrument using re hargeable batteries.
• Please use only type "NiMH" reusable batteries!
• If the battery symbol ( ) appears, the batteries must be removed and
re harged! They must not remain inside the instrument, as they may be ome
damaged through total dis harge even when swit hed off. The batteries must
NOT be dis harged in the blood pressure monitor! If you do not intend to use
the instrument for a week or more, always remove the re hargeable batter-
ies!
• Re harge these batteries using an external harger and follow manufa turer’s
instru tions arefully.

5.11. Using the AC Adapter
You may also operate this monitor using the in luded AC Adapter (output 6V
DC/600 mA with DIN plug).
Use only the in luded AC Adapter to avoid damaging
the unit.
1. Ensure that the AC adapter and able are not damaged.
2. Plug the adapter able into the AC Adapter port
on the blood pressure monitor.
3. Plug the adapter into your ele tri al outlet.
When the AC adapter is onne ted, no battery urrent is onsumed.
Note: No power is taken from the batteries while the AC Adapter is onne ted to
the monitor. If ele tri al power is interrupted, (e.g., by a idental removal of the
AC adapter from the outlet) the monitor must be reset by removing the plug from
the so ket and reinserting the AC adapter onne tion. Please onsult Mi rolife if
you have any questions regarding the AC adapter by alling 1-800-568-4147.
6. Software Functions
This unit an be used in onne tion with
your personal omputer (PC) running the
PC Link Blood Pressure Analyzer soft-
ware. Your PC will allow a apa ity of
monitoring 80 patients, ea h with 1000
data (note: overuse will lower system
effi ien y). The memory data an be
transferred to the PC by onne ting the monitor via the in luded USB able with
your PC. Note: The software does not work with Ma omputers.
6.1. Installation and Data Transmission
a) Insert CD into CD ROM drive of your PC. The installation
will start automati ally. If not, li k on SETUP.EXE.
b) Conne t the monitor via USB able with the PC. Three
hori-
zontal bars will appear on the display and last for 3 se onds.

• Che k battery installation or AC
adapter onne tion is orre t and
wall outlet is working.
• If the display is unusual, remove the
batteries and then ex hange them for
new ones.
Che k polarity.
• Che k the onne tion of the uff tube
and onne t properly.
1. Ensure the uff fits properly. (see 5.3)
2. Before starting measurement make
sure that the uff is not too tight and
that lothing is not exerting pressure
on the arm. Take arti les of lothing
off if ne essary.
3. Measure blood pressure again in
omplete pea e and quiet.
• Please read the following information
and the points listed under “Common
sour es of error”.(5.2) Repeat the
measurement.
• Blood pressure hanges onstantly.
The observed readings may a u
rately refle t your pressure.
• Re ord daily values and onsult
your do tor.
• Pressure readings in your do tor’s
offi e may be higher due to anxiety.
• Che k uff onne tions.
Ensure the unit has not been
tampered with.
The display remains blank when the instru-
ment is swit hed on although the batteries
are in pla e.
The pressure does not rise although the
pump is running.
The devi e frequently fails to measure,
or the values measured are too low or high.
Every measurement results in different val-
ues, although the devi e fun tions normally
and normal values are displayed.
Blood pressure values differ from those
measured by my do tor.
After the instrument has inflated the uff
the pressure falls very slowly, or not at all.
(No reasonable measurement possible).
