☞ Further Information
The level of blood-pressure is subject to fluctuations even with healthy people. Important
thereby is, that comparable measurements always require the same conditions (Quiet
conditions)!
If, in spite of observing all these factors, the fluctuations are larger than 15 mmHg, and/or you
hear irregular pulse tones on several occasions, please consult your doctor.
You must consult your specialist dealer or chemist if there are technical problems with the
blood-pressure instrument. Never attempt to repair the instrument yourself! Any unautho-
rised opening of the instrument invalidates all guarantee claims!
7. Care and maintenance, recalivration
a) Do not expose the device to either extreme temperatures, humidity,
dust or direct sunlight.
b) The cuff contains a sensitive air-tight bubble. Handle this carefully
and avoid all types of straining through twisting or buckling.
c) Clean the device with a soft, dry cloth. Do not use petrol, thinners or
similar solvent. Spots on the cuff can be removed carefully with a
damp cloth and soapsuds. The cuff must not be washed!
The device frequently fails to
measure the blood pressure val-
ues, or the values measured are
too low (too high).
1. Check the positioning of the cuff.
2. Measure the blood pressure again in complete peace and
quiet under observance of the details made under point 5.
Every measurement results in
different values although the
device functions normally and
the values displayed are normal.
• Please read the following information and the points listed
under «Common sources of error». Repeat the measure-
ment.
The blood pressure values
measured differ from those
measured by the doctor.
• Record the daily development of the values and consult
your doctor about them.
