1. Introduction
1.1. Features of your blood pressure monitor
This blood pressure monitor, with integrated time/date display, is a fully automatic, digital blood pressure measuring device for use on the wrist. It enables
very fast and reliable measurement of the systolic and diastolic blood pressure
as well as pulse by way of the oscillometric method of measuring.
This device offers a very high degree of accuracy demonstrated through clinical
studies. It is also very easy to use.
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
• Caution: Self measurement of blood pressure helps your health
care professional assist in the management of your blood pressure.
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 functioning of heart
pacemakers!
•
In cases of cardiac irregularity, measurements made
with this instrument should only be evaluated by your doctor.
Electromagnetic interference:
The device contains sensitive electronic components (Microcomputer).
Therefore, avoid strong electrical or electromagnetic fields in the direct vicinity
of the device, such as cellular telephones and microwave ovens. These
devices, when in operation close to your blood pressure monitor, can lead to
temporary impairment 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 a part of the brain called the circulatory center. This part of your brain responds to a situation through feedback
with the nervous system.To adjust the 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 altered by fine muscles in the blood vessel walls.
The level of arterial blood pressure changes periodically during heart activity:
During blood ejection from the heart (Systole) the value is maximal (systolic
blood pressure value). At the end of the heart’s ‘rest period’, Diastole or diastolic blood pressure value, blood pressure falls to a low value. 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 at rest, your diastolic pressure is above 90mmHg
and/or the systolic blood pressure is over 160mmHg.
You should bring these
values to the attention of your doctor immediately. Long-term values at
this level endanger your health due to the associated advancing damage to the blood vessels in your body.
Should the systolic blood pressure values lie between 140mmHg and
160mmHg and/or the diastolic blood pressure values between
90mmHg and 95mmHg, please consult your doctor, and check your
blood pressure regularly.
With blood pressure values that are too low, i.e. systolic values under
105mmHg and/or diastolic values under 60mmHg, please 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, in consultation with your physician.
If you are undergoing medical treatment to control your blood pressure, please
keep a record of your blood pressure levels 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 discontinue or independently alter the drug doses prescribed by your doctor.
The following standards for assessing high blood pressure (without regard to age)
have been established by the National Institutes of Health JNC7.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 <80
Self-Check
Pre-Hypertension 120 - 139 80 - 89
Stage 1 140 - 159 90 - 99
Hypertension
Stage 2 >160 >100
Hypertension
☞ Further information
• If your values are mostly standard 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”. Please
consult your doctor if you suspect that this might be the case.

Warning:
• Diastolic blood pressure values above 120mmHg require immediate
medical treatment
.
2.3. What can be done if your blood pressure values are consistently
high or low?
a) Please consult your doctor.
Increased blood pressure values (various forms of hypertension) are
associated with considerable health risks. The concern is the arterial
blood vessels of your body, which are endangered due to constriction
caused by deposits in the vessel walls. (Arteriosclerosis) This can and does
cause deficient supply of blood to important organs such as the heart,
brain, and muscles. Furthermore, with long-term continuously increased
blood pressure values, the heart will become structurally damaged.
There are many different causes of high blood pressure. We differentiate
between common primary (essential) hypertension, and secondary
hypertension. Secondary hypertension (high) can be related to specific
organ malfunctions. Please consult your doctor for information about the
possible origins of your own increased blood pressure values.
Lifestyle changes may assist in the reduction of a medically established
high blood pressure prevention. These lifestyle changes should be
practiced on a continual basis:
1. Eating habits
• Strive for a healthy weight corresponding to your age.
• Avoid excessive consumption of common salt.
(Many packed foods contain large amounts of salt.)
• Avoid fatty foods.
5
2. Previous illnesses
Consistently follow any medical instructions for treating previous illness
such as:
• Sugar Diabetes (Diabetes mellitus);
• Fat metabolism disorder, and;
• Gout.
3. Habits
• Smokers should give up smoking completely.
• If you drink alcohol, do so in moderate amounts only.
• Restrict your caffeine consumption (Coffee, coke, tea, chocolate, etc.).
4. Physical constitutioning:
• After a medical examination and clearance from your doctor, exercise
regularly.
• 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 physical activities. Your
doctor will advise you regarding the physical activities that are
best for you.

5. Carrying out a measurement
5.1. Before the measurement:
• Avoid eating, smoking, and all forms of exertion before taking your
blood pressure.
All these factors influence the measurement result. Try to find time to
relax by sitting in an armchair in a quite atmosphere for about ten minutes
before measurement.
• Always measure on the same wrist (normally left).
• Attempt to measure regularly 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! Taking pressure when relaxed in a quiet environment is
important.
• All efforts to hold your arm up 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.
•
It is very important to have your blood pressure monitor at heart level.
Support your arm with a pillow. Taking your pressure with the
monitor lower than heart level results in a false high reading.
If the monitor is higher than heart level, a false low reading will result.
