1. Introduction
1.1. F atur s of your Automatic Blood Pr ssur Monitor
Your blood pressure monitor 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
the systolic and diastolic blood pressure as well as the pulse by way of the
oscillometric method. This device offers clinically proven accuracy and has
been designed to be 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.
Att ntion!
1.2. Important information about s lf-m asur m nt
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, measurements made with this instru-
ment should only be evaluated after consultation with your doctor.
El ctromagn tic int rf r nc :
The device contains sensitive electronic components. Avoid strong electri-
cal or electromagnetic fields in the direct vicinity of the device (e.g.,
mobile telephones, microwave ovens). These can lead to temporary impair-
ment of the measuring accuracy.
2. Important information on blood pr ssur and its m asur m nt
2.1. How do s high/low blood pr ssur aris ?
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 circulatory 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),
2

pressure is lowest (diastolic blood pressure value).
Blood pressure values must lie within certain normal ranges in order to
prevent particula r diseases.
2.2. Which valu s ar normal?
Blood pressure is too high if your diastolic pressure is above 100 mmHg
and/or your systolic blood pressure is over 160 mmHg, whil at r st. In
this case, please consult your physician immediately. Long-term values at
this level endanger your health due to continual damage to the blood
vessels in your body.
If your systolic blood pressure values are between 140 mmHg and 159
mmHg and/or the diastolic blood pressure values are between 90 mmHg
and 99 mmHg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values
under 105 mmHg and/or diastolic values under 60 mmHg), consult your
physician.
Even with normal blood pressure values, a regular self-check with your
blood pressure 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 record of values along with time of day and date. Show these
values to your physician. N v r us th r sults of your m asur m nts
to ind p nd ntly alt r th drug dos s pr scrib d by your
physician.
Which valu s ar normal?
The following standards for assessing high blood pressure (in adults) have
been established by the National Institutes of Health JNC7, 2003.
3
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

+ Furth r information
If your values are mostly normal under resting conditions but exception-
ally 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 120 mmHg
require immediate medical treatment.
This d vic is not int nd d for us on childr n 12 y ars of ag or
young r.
2.3. What can b don if r gular high or low valu s ar obtain d?
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
arteriosclerosis. Furthermore, the heart will become structurally
damaged with increased blood pressure values.
c) There are many different causes of high blood pressure. We differenti-
ate between the common primary (essential) hypertension and second-
ary 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 pressure. These measures must be permane nt lifestyle
changes.
1) 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.
2) Pr vious illn ss s
Consistently follow all medical instructions for treating illness such as:
Diabetes (diabetes mellitus)
Fat metabolism disorder
Gout
4

5
3) Habits
Give up smoking completely.
Drink only moderate amounts of alcohol.
Restrict your caffeine consumption (e.g., coffee).
4) Physical constitution
• Aft r a pr liminary m dical xamination, do r gular x rcis .
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.

socket (U.S. or Canada).
d) Test that power is available by pressing
the POWER button.
Not :
No power is taken from the batteries
while the AC adapter is connected to the
instrument.
If the power is interrupted during a
measurement (e.g., by removal of the
adapter from the wall socket), the instru-
ment must be reset by removing the plug
from the instrument.
If you have any questions regarding the AC
adapter, call us at 1-800-568-4147.

4.6. S l ct m asuring mod : standard or
Microlif Av raging Mod (MAM)
This instrument enables you to select either standard
(single measurement) or measurement a
veraging
mode (automatic triple measurement).
a) To select Standard mode, push the switch on the
side of the instrument upward to Position "1."
b) To select Averaging mode, push the switch
downward to Position "3." Note the "MAM" icon
will illuminate on the display.
If you select 1, then only one measurement will be
taken. If you select 3, the unit will inflate and deflate
three times resulting in one final average.
4.7. Microlif Av raging Mod (MAM)
In Microlife Averaging Mode (MAM), three measurements are automati-
cally taken in succession and the result is then automatically analyzed
and displayed. Because your blood pressure constantly fluctuates, a
result determined in this way is more reliable than one produced by a
single measurement.
After pressing the POWER button the selected Microlife Averaging
Mode appears in the display as the MAM symbol.
The bottom, right-hand section of the display shows a 1, 2 or 3 to
indicate which of the 3 measurements is currently being taken.

5. M asur m nt proc dur
Pl as not : You should always b s at d b for and during
m asur m nt.
5.1. B for m asur m nt:
Avoid eating and smoking as well as all forms of exertion directly before
measurement. These factors influence the measurement result. Find time
to relax by sitting in an armchair in a quiet atmosphere for about ten
minutes before your measurement.
Remove any garment that fits closely to your upper arm.
Always measure on the same arm (normally left).
Compare measurements at the same time of day, since blood pressure
changes during the course of the day (as much as 20–40 mmHg).
5.2. Common sourc s of rror
Not : Comparabl blood pr ssur m asur m nts always r quir
th sam conditions. Conditions should always b qui t.
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 15 cm
(6”) difference in height between your heart and the cuff 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 extremely important. 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 call 1-800-568-4147.
A loose cuff or a sideways protruding air pocket causes false measure-
ment 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 your arm has been held up
in order to allow the accumulated blood to flow away.
10

5.3. Fitting th cuff
a) Pass the end of the cuff through the flat
metal ring so that a loop is formed. The
hook and loop material must be facing
outward. (Ignore this step if the cuff has
already been prepared.)
b)
Slide the cuff onto your upper left arm. The
rubber tube should be on the inside of your
arm extending downward to your hand.
Make certain the cuff lies approximately
1/2” to 3/4” (1 to 2 cm) above the elbow.
IMPORTANT: The red strip on the edge of
the cuff (Artery Mark) must lie over the artery
which runs down the inner side of the arm.
TIP: Align red artery mark to pinky finger.
c) To secure the cuff, wrap it around your
arm and press the hook and loop material
together. Check the size range indicator on
the cuff. The green arrow should point
within the green size range on the inside
of the cuff.
d) There should be little free space between
the arm and the cuff. You should be able
to fit 2 fingers between your arm and the
cuff. Clothing must not restrict the arm.
Any piece of clothing which does must be
removed. Cuffs that don’t fit properly
result in false measurement values.
Measure your arm circumference if you
are not sure of proper fit.
e) Lay your arm on a table so the cuff is at
the same height as your heart. Make sure
the tube is not kinked.
f) Remain seated quietly for five minutes
before you begin the measurement.

Comm nt
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. M asuring proc dur
After the cuff has been appropriately positioned the
measurement can begin:
a)
Press the POWER button. After the system check, the
monitor displays OK and
the pump begins to inflate
the cuff. On the display, the increasing cuff
pressure is continually shown.
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, the
air will automatically release from the cuff. The
measured systolic and diastolic blood pressure
values, as well as the pulse, are now displayed.
e) The measurement results are displayed until you
switch the device off. If no button is pressed for 1
minute, the device switches off automatically.

f) When the unit is set to the MAM (Microlife Averaging Mode) setting, 3
separate measurements will take place in succession, after which your
result is calculated and displayed as a single, averaged measurement
(individual results are not displayed). There is a 15 second resting time
between each measurement. A count-down indicates the remaining time
between measurements.
If one of the measurements causes an error message, it will be repeated
one more time. If any additional error occurs, the measurement will be
discontinued and error code displayed.

5.5. M mory – displaying th last 99 masur m nts
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.
Vi wing th stor d valu s
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 viewing the measurements 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.
Mmory full
When the memory has stored 99 results, a new, measured value is stored
by overwriting the oldest value.
Cl ar all valu s
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 POWER
button. To permanently clear the memory, press the
"M" button while "CL" is flashing.
Individual values cannot be cleared.
5.6. Discontinuing a m asur m nt
If it is necessary to interrupt a blood pressure measurement for any reason
(e.g., the patient feels unwell), the POWER button can be pressed at any
time. The device then immediately lowers the cuff pressure automatically
and enters sleep mode.

5.7. Hyp rt nsion risk indicator
The bars on the left-hand edge of the display show you the range within
which the indicated blood pressure value lies. Depending on the position
of the triangle indicator, the readout value is either within the normal
(green), borderline (yellow) or danger (orange, dark orange) range.
The classification is based on standards established by the National
Institutes of Health JNC7, 2003.
Refer to the chart in section 2.2 of this instruction manual for details of the
classifications.
A triangle is displayed to the right of the traffic light bar according to your
measurement.
If your triangle is in the green zone, your measurement is "Normal,"
according to NIH standards.
If your triangle is in the yellow zone, your measurement is "Pre-Hypertension."
If your triangle is in the orange zone, it is "Stage 1 Hypertension."
If your triangle is in the dark orange zone, it is "Stage 2 Hypertension.".

5.8. Irr gular h artb at d t ctor
The appearance of 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
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 on fr qu nt app aranc of th irr gular h artb at 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 the measurement, the irregular
heartbeat symbol is displayed with the measurement.
If the symbol appears frequently or if it suddenly appears more often than
usual, we recommend the patient seek medical advice. The instrument
does not replace a cardiac examination but serves to detect pulse irregu-
larities at an early stage.

5.9. Batt ry charg indicator
Batt ri s almost discharg d
When the batteries are approximately 75% used, the
battery symbol will flash a few times as soon as the
instrument is switched on (if at least one of the batter-
ies still has some charge). Although the
instrument will
continue to measure reliably, you
should obtain replacement batteries.
Batt ri s discharg d – r plac m nts r quir d
When the batteries are discharged, the battery symbol
will appear, unblinking, as soon as the instrument is
switched on. You cannot take any further measure-
ments and must replace the batteries.
1. Open the battery compartment on the bottom of the instrument.
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 will flash automati-
cally after the batteries are replaced.
4. To set date and time, follow the procedure described in Section 4.3.
Not :
Use four new, Long-Life 1.5 V 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 r charg abl batt ri s
You can also operate this instrument using rechargeable batteries.
Please use only type "NiMH" reusable batteries.
If the battery symbol ( ) appears, the batteries must be removed
and recharged. They must not remain inside the instrument, as they may
become damaged through total discharge even when switched off. The
batteries must NOT be discharged in the blood pressure monitor. If you
do not intend to use the instrument for a week or more, always remove
the rechargeable batteries.
Recharge these batteries using an external charger and follow manufac-
turer’s instructions carefully.

6. Softwar functions
This unit can be used in connection
with your personal computer (PC)
running the PC Link blood pressure
analyzer software. Your PC will allow
a capacity of monitoring 80 patients,
each with 1000 data (note: overuse
will lower system efficiency). The
memory data can be transferred to the
PC by connecting the monitor via the
included USB cable.
Note: The software does not work with
Mac computers.
6.1. Installation and data transmission
a) Insert CD into CD ROM drive of your PC. The
installation will start automatically. If not,
click on SETUP.EXE.
b) Connect the monitor via USB cable with the
PC. Three horizontal bars will appear on the
display and last for 3 seconds.
c) The bars will then flash to indicate that the
connection between computer and device is
successfully made. As long as the cable is
plugged, the bars will keep flashing and the
buttons are disabled.
During the connection, the device is completely
controlled by the computer. Please refer to the
"Help" file in the software for detailed instruc-
tions or call 1-800-568-4147.

7. Error m ssag s/troubl shooting
If an error occurs during a measurement, the measure-
ment is discontinued and a corresponding error code is
displayed (example: Error no. 2).
Error No. Possibl caus (s)/Solutions
ERR 1 The tube may have loosened, or no pulse was detect-
ed.* Ensure
cuff connections are tight with proper cuff
placement. See section 5.3.
ERR 2 Unnatural pressure impulses influenced the measure-
ment result. Reason: The arm was moved during the
measurement (artefact). Repeat measurement,
keeping still and quiet.
ERR 3 Inflation of the cuff takes too long. The cuff is not
correctly seated or the hose connection is not tight.
Re-position cuff and repeat the measurement.
ERR 5 The measured readings indicated an unacceptable
difference between systolic and diastolic pressures.
Take another reading following directions carefully.
Contact your doctor if you continue to get unusual
readings.
HI The cuff pressure is too high. Relax for 5 minutes
and repeat the measurement.*
LO The
pulse is too low (less than 40). Repeat the
measurement.*
*If this or any oth r probl m occurs r p at dly, pl as consult
your doctor.
