Other possible malfunctions and their elimination
If problems occur when using the device, the following points should be
checked and if necessary, the corresponding measures are to be taken:
Malfunction
The display remains blank when the
instrument is switched on although
the necessary insert correctly.
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
Blood pressure values measured differ
from those values
Remedy
1.Check batteries for correct polarity and if batteries are in place.
2.If the display is unusual, re-insert batteries or
exchange them.
1.Check the positioning of the cuff.
2.Measure the blood pressure again in peace
and quiet under observance of the details
made in Section 5.
1.Please read the following information and
listed in Section 5.2
"Common sources of
error
."
Repeat the measurement.
Please note: Blood pressure fluctuates
continually so successive measurements
will show some variability.
1.Record the daily development of the
measured by the doctor and consult your
doctor.
Please note: Individuals visiting their doctor
frequently experience anxiety which can
result in a higher reading at the doctor than
obtained at home under resting conditions
.
☞ Further Information
Your level of blood pressure is subject to fluctuations even with
healthy people. Comparable measurements always require the same
conditions (Quiet conditions)! If, in spite of observing all these factors,
the fluctuations are larger than 15mmHg, and/or you hear irregular
pulse tones, please consult your doctor. For licensing, this device has
been subjected to strict clinical tests. The computer program used to
measure the blood pressure values was tested by experienced specialist physicians in Germany. The same computer program is used in
every individual device, and has also been clinically tested. The manu-
facture of the devices takes place according to the terms of the
European standard for blood pressure measuring devices (see technical
data) under the supervision of the Technical Monitoring Association
Essen (RWTüV-Essen). You must consult Microlife 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 warranty claims!
8. 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 bub-
ble. 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 gasoline, thinners or similar solvents. 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 anyway. Avoid strong vibrations.
e)Never open the device! Otherwise the
manufacturercalibration becomes invalid!
