and/or diastolic values under 60mmHg, likewise, please consult your doctor.
Even with normal blood-pressure values, a regular self-check with your blood-pres-
sure monitor is recommended. In this way you can detect possible changes in your
values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, please
keep a record of the level of your blood pressure by carrying out regular self-mea-
surements at specific times of the day. Show these values to your doctor. Never use
the results of your measurements to alter independently the drug doses prescri-
bed by your doctor.
Table for classifying blood-pressure values (units mmHg):
Range Systolic Blood-pressure Diastolic Blood-pressure Measures
(maximum) (minimum)
Hypotension lower than 100 lower than 60 Check with your
doctor
Normal range between 100 and 140 between 60 and 90 Self-check
Mild hypertension between 140 and 160 between 90 and 100 Consult your doctor
Moderately serious between 160 and 180 between 100 and 110 Consult your doctor

Serious hypertension higher than 140 higher than 110 Urgent!

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.
• Correctly measured diastolic blood-pressure values above 120mmHg requi-
re immediate medical treatment.
Electromagnetic interference:
The device contains sensitive electronic components (Microcomputer). Therefore,
avoid strong electrical 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 THE SUBJECT OF
BLOOD-PRESSURE AND ITS MEASUREMENT
2.1. How does high/low blood-pressure arise?
The level of blood-pressure is determined in a part of the brain, the so-called cir-
culatory centre, and adapted to the respective situation by way of feedback via 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. The latter is effected by way of
fine muscles in the blood-vessel walls.
The level of arterial blood-pressure changes periodically during the heart activity:
during the ‘blood ejection‘ (Systole) the value is maximal (systolic blood-pressure
value), at the end of the heart’s ‘rest period’ (Diastole) it is minimal (diastolic blood-
pressure value).
The 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 the systolic blood-pressure is over 160mmHg
and/or the diastolic blood-pressure is above 90mmHg. In this case, please consult
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 lie between 90mmHg and 100mmHg, like-
wise, please consult your doctor. Furthermore, regular self-checks will be necessary.
With blood-pressure values that are too low, i.e. systolic values under 105mmHg
