Malfunction
The display remains empty when the
instrument is switched on although the
batteries are in place.
The device frequently fails to measure the
blood pressure values, or the values measured
are too low (too high).
Every measurement produces a different
value although the instrument functions
normally and the values displayed are normal.
Blood pressure measured differ from those
values measured by the doctor.
☞ Further Information
The level of blood-pressure is subject to fluctuations even with healthy people. Therefore it is important
to ensure that to compare measurements always requires the same conditions (Quiet conditions)!
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 unauthorised opening of the instrument invalidates all guarantee claims!
9. Care and maintenance, recalibration
a) Do not expose the device to either extreme temperatures, humidity, dust or direct sunlight.
b) The cuff contains a sensitive air-tight compartment. 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!
