1. Introduction
1.1. Features of the Wrist Blood Pressure Monitor
This blood pressure monitor (with Irregular Heartbeat Detection) is a fully
automatic digital blood pressure measuring device for use on the wrist.
This monitor enables very fast and reliable measurement of your systolic
and diastolic blood pressure as well as pulse by way of the oscillometric
method of measuring. This device offers a very high and clinically tested
measurement accuracy and is designed for maximum user-friendliness.
Before using it please read through this instruction manual carefully and
keep it in a safe place. For further questions on the subject of blood pres-
sure 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 physician. You should never
alter the dosages of any medication without direction from your
physician. The pulse display is not suitable for checking the functioning of
heart pacemakers!!
In cases of irregular heartbeat, measurements made with this
instrument should only be evaluated after consultation with your
doctor.
Electromagnetic Interference: This device contains sensitive electronic
components. Avoid strong electrical or electromagnetic fields in the direct
vicinity of the device (e.g. mobile telephones microwave ovens etc.). These
can lead to temporary impairment of the monitor’s
measuring accuracy.
2. Important information about 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 circulatory blood

vessels is altered. Blood vessel width is affected by way of 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). Your blood pressure values
must lie within certain normal ranges in order to prevent particular diseases.
2.2 Which values are normal?
Blood pressure is too high if your diastolic pressure is above 100 mmHg
and/or your systolic blood pressure is over 160 mmHg while at rest. In this
case please consult your physician immediately. Long-term values at this level
endanger your health through continual damage to the blood vessels in you
body. Should your systolic blood pressure values lie between 140 mmHg and
159mmHg and/or your diastolic blood pressure values lie between 90 mmHg
and 99mmHg. Consult your physician. Regular self-checks will be 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
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. 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 reagard to
age) have been established by the U.S. National Institutes of Health JNC7 2003.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 and <80
Self-Check
Pre-Hypertension 120 - 139 or 80 - 89
Stage 1 140 - 159 or 90 - 99
Hypertension
Stage 2 ≥160 or ≥100
Hypertension

☞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
your are suffering from so-called "labile hypertension." Consult your physi-
cian.
• Correctly measured diastolic blood pressure values above 120mmHg
require immediate medical treatment.
* This device is not intended for use on children 12 years of age or
younger.
2.3 What can be done if regular high/low values are obtained?
a) Consult your physician.
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 constrictions caused by deposits in the
vessel walls (Arteriosclerosis). A deficient supply of blood to important
organs (heart brain muscles) can result. 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. Secondary hypertension can be ascribed to specific organ
malfunctions. Please consult your physician for information about the pos-
sible origins of your own increased blood pressure values.
d)There are measures you can take to reduce and even prevent high
blood pressure. These measures must be permanent 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.

6
) Previous illnesses
• Consistently follow all medical instructions for treating illness such as:
diabetes (diabetes mellitus or sugar diabetes) fat metabolism disorder
and gout.
3) Habits
• Give up smoking completely.
• Drink only moderate amounts of alcohol.
• Restrict your caffeine consumption (coffee tea and chocolate).
4) 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 physician before beginning your exercise routine. You
must receive advice regarding the type and extent of exercise that is
appropriate for you.
2.4 Irregular Heartbeat Detection
The appearance of the symbol signifies that a certain irregular
heartbeat was detected which could cause cardiovascular disease. This
indicator is only a caution. This blood pressure monitor can detect blood
pressure and pulse rate measurement with specifications even if the
patient is having an irregular heartbeat interval. 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
icon frequently.
CAUTION: An irregular heartbeat can be a serious medical condition
requiring medical attention. See your doctor if you have an irregular
heartbeat.

4. Using your Blood Pressure Monitor for the First Time
4.1. Activate the Pre-Installed Batteries
Pull out the protective strip protruding from the battery compartment.
4.2 Setting the date and time
1. After the new batteries are activated the year num-
ber flashes in the display. You can advance the year
by pressing the "M" button. To confirm and then set
the month press the time button.
2. You can now set the month using the “M” button. To
confirm and then set the day press the time button.
3. Please follow the instructions above to set the day
hour and minutes.
4. Once you have set the last minute and pressed the
time button the date and time are set and the time
is displayed.
5. If you want to change the date and time press and
hold the time button down for approx. 3 seconds
until the year number starts to flash. Now you can
enter the new values as described above.
5. Taking a Blood Pressure Measurement
5.1. Before the measurement:
• Avoid eating smoking as well as all forms of exertion directly before
your measurement. These factors influence the measurement result.
Relax by sitting in an armchair in a quiet atmosphere for about ten
minutes before your measurement.
• Always measure on the same wrist (normally left).
• Compare readings at the same time of day since your 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 the arm can increase blood pres-
sure. Make sure you are in a comfortable relaxed position and do not
activate any of the muscles in the measurement arm during the mea-
surement. Use a cushion for support if necessary.
• If the wrist artery lies considerably lower (higher) than the heart an
erroneously higher (lower) blood pressure will be measured! (Each
15cm/6" difference in height results in a measurement error
of10mmHg!)
• A loose cuff causes false measurement values.
• With repeated measurements blood can accumulate in the respective
arm which can lead to false results. Correctly executed blood pressure
measurements should therefore first be repeated after a 1 minute
pause or after the arm has been held up in order to allow the accumu-
lated blood to flow away.
5.3. Fitting the cuff
a) Remove all objects and jewelry (e.g.
wristwatch) from the wrist in use. Put the
cuff over the wrist with the monitor face
on the inside of the wrist.
b) The distance between the cuff and the
hand should be approx. 10 mm (1/2").
c) Secure the cuff with the Velcro fastener
so that it lies comfortably and not too
tight. No space should remain between
the cuff and the wrist.
