Notes on use
•
In order to ensure comparable values, always measure your
blood pressure at the same time of day.
•
Before every measurement, relax for about five minutes.
•
If you want to perform several measurements on the same
person, wait ve minutes between each measurement.
•
Do not take a measurement within 30 minutes of eating,
drinking, smoking or exercising.
•
Repeat the measurement if you are unsure of the measured
value.
•
The measured values taken by you are for your information
only – they are no substitute for a medical examination. Dis-
cuss the measured values with your doctor and never base
any medical decisions on them (e.g. medicines and their
administration).
•
Do not use the blood pressure monitor on newborns or
patients with preeclampsia. We recommend consulting a
doctor before using the blood pressure monitor during preg-
nancy.
•
In the case of restricted circulation on the arm as a result of
chronic or acute vascular diseases (including vascular con-
striction), the accuracy of the wrist measurement is limited.
In this case you should avoid using an upper arm blood
pressure monitor.
•
Cardiovascular diseases may lead to incorrect measure-
ments or have a detrimental effect on measurement accura-
cy. The same also applies to very low blood pressure, diabe-
tes, circulatory disorders and arrhythmias as well as chills or
shaking.
•
The blood pressure monitor must not be used in connection
with a high-frequency surgical unit.
•
Only use the unit on people who have the specied wrist
measurement for the device.

•
Wait at least 5 minutes before taking an-
other measurement.
6. Evaluating results
Irregular heartbeat:
This device can identify potential disruptions of the heart
rhythm when measuring and if necessary, indicates this after
the measurement with the symbol .
This can be an indicator for irregular heartbeat. Irregular heartbeat
is a condition in which the heart rhythm is abnormal because of
flaws in the bioelectrical system that regulates the heartbeat. The
symptoms (skipped or premature heart beats, pulse being slow or
too fast) can be caused by factors such as heart disease, age,
physical
![](/img.php?id=3380295&img=bga.png)
make-up, excess stimulants, stress or lack of sleep. Irregular
heartbeat can only be determined through an examination by
your doctor.
If the symbol is shown on the display after
the measure-ment has been taken, repeat the measurement.
Please ensure that you rest for 5 minutes beforehand and do
not speak or move during the measurement. If the symbol
appears frequently, please consult your doctor.
Self-diagnosis and treatment based on the measurements can
be dangerous. Always follow your GP’s instructions.
Classication of measurements:
The measurements can be classied and evaluated in accord-
ance with the following table.
However, these standard values serve only as a general guide-
line, as the individual blood pressure varies in different people
and different age groups etc.
It is important to consult your doctor regularly for advice. Your
doctor will tell you your individual values for normal blood
pressure as well as the value above which your blood pressure
is classied as dangerous.
The classication on the display and the scale on the unit show
which category the recorded blood pressure values fall into. If
the values of systole and diastole fall into two different cate-
gories (e.g. systole in the ‚High normal‘ category and diastole
in the ‚Normal‘ category), the graphical classication on the de-
vice always shows the higher category; for the example given
this would be ‚High normal‘.
