• When the measurement is finished, you will be given another
opportunity to change the memory to which the measured
value is to be saved. To do this, press the Memory button of
the user for whom the measured value is to be saved.
• The device switches itself off after approximately 3 minutes.
You can also switch the device off before this by pressing the
Start/Stop button.
If the acoustic signal is too weak, the microphone integrated in
the cuff will not be able to record the Korotkoff sounds of the
blood flow without errors.
In this case, the measurement values are deter-
mined according to the oscillometric procedure
(see page 38). The measurement values are in-
dicated together with the symbol
(Image 5).
In this case, check whether the cuff and the mi-
crophone are correctly seated and whether the
microphone jack has been fully inserted into the
device. Repeat the measurement. During the measurement, the
palm of the hand must be turned upwards.

11. Classification of the measured values (WHO)
The device categorises the blood pressure read-
ings according to the 1999 guidelines of the
World Health Organisation (WHO). You can de-
termine the classification after each measure-
ment using the triangle in the display and the
colour fields next to the display.
Classification
Systolic pressure
= top value
mmHg
Diastolic pressure
= bottom value
mmHg
Stage 3 hypertension
≥ 180
≥ 110
Stage 2 hypertension
160-179
100-109
Stage 1 hypertension
140-159
90-99
High-normal
130-139
85-89
Normal
120-129
80-84
Optimal
< 120
< 80
The WHO classification is stored along with the measured values
and both can be recalled from the memory.
Depending on age, weight and general health, the blood pressure
values can be different. Only a doctor can determine the right
blood pressure range for you and assess whether your blood
pressure has reached a dangerous level for you. Discuss your
blood pressure values with your doctor.
Never change the dose
of medicines prescribed by your doctor!
The pulse pressure – not to be confused with the pulse beat –
provides an indication of the elasticity of the blood vessels. A stiff
system of vessels can have a negative effect on the cardiovascu-
lar system. Studies show that the cardiovascular risk increases if
the pulse pressure value is permanently higher than 65 mmHg.
12. Pulse pressure
The heart works in two phases, the contraction phase (expulsion
phase, systole) and the relaxation phase (filling or resting phase,
diastole). The pressure difference between systole and diastole
