Dear Customer
• Important: Blood pressure measurement is not sui-
table in cases of serious arteriosclerosis (hardening
of the arteries).
• The pulse display is not suitable for monitoring the
frequency of cardiac pacemakers.
• If you suffer from disorders of heart rhythm, known
as arrythmia, you should only use this blood pres-
sure monitor in consultation with your doctor. In cer-
tain cases the oscillometric measuring method can
produce incorrect readings.
• Pregnant women should only measure their own
blood pressure in consultation with their doctor,
since the readings may be changed by pregnancy.
• You should avoid eating, drinking (alcohol), smoking
and sports before measuring your blood pressure,
as this could affect your blood pressure level.
• Don’t
move, don’t speak while measurement is
being taken.
• Make yourself comfortable in a chair and relax
before each reading.
• We recommend that you monitor your blood pres-
sure twice a day, in the morning after getting up and
in the evening after work, or as advised by your
doctor.
• Please remember: Self-measurement is not the
same as medical treatment!
You should never change the dose of medicines
prescribed by your doctor.
