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!
7. Care and maintenance, recalibration
a) Do not expose the device to either extre me 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!
d) Do not drop the instrument or treat it roughly in any way. Avoid
strong vibrations.
e) Never open the device! Otherwise the manufacturer calibra-
tion becomes invalid!
Periodical recalibration
Sensitive measuring devices must from time to time be checked
for accuracy. We therefore recommend a periodical inspection of
the static pressure display
every 2 years
.
Your specialist dealer would be pleased to provide more exten-
sive information about this.
