7. 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 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) Handle the tube carefully. Do not pull on it. Likewise, this is
not to be buckled or laid over sharp edges.
e) Do not drop the instrument or treat it roughly in any way.
Avoid strong vibrations.
f) Never open the device! Otherwise the manufacturer
calibration becomes invalid!
g) Remove the batteries if the device will not be used for a
long time. Do not use batteries beyond their date of expiry.
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 extensive information about this.
8. Guarantee
The ‘as easy as 123’ blood-pressure monitor is guaranteed for 2 years from date of purchase. This
guarantee includes the instrument and the cuff. The guarantee does not apply to damage caused by
improper handling, accidents, not following the operating instructions or alterations made to the instrument
by third parties. Please retain your proof of purchase to confirm the start of your 2 year guarantee period.
Other possible malfunctions and their eliminations
If problems occur when using the device, the following points should be checked and if necessary, the
corresponding measures are to be taken:
☞ 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)!
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!

ERR 3 Inflation of the cuff takes too long. The cuff is not correctly seated or the hose connection is
not sealed
ERR 5 The measured results have indicated an unacceptable difference between the systolic and
diastolic pressure. Take another measurement, carefully following the instructions. Contact
your doctor, if you still obtain unusual results.
LO Below 40 pulses per min.
HI 200 or more pulses per min.
Malfunction Remedy
The display remains empty when the instrument
is switched on although the batteries are in
place.
1. Check whether the batteries are installed with the
correct polarity and correct if necessary.
2. If the display is unusual, remove the batteries and
then exchange them for new.
The pressure does not rise although the pump is
running.
• Check the connection of the cuff tube and connect
properly if necessary.
The device frequently fails to measure the blood
pressure values, or the values measured are too
low (too high).
1. Fit the cuff correctly on the arm.
2. Before starting the measurement make sure that the
cuff is not fitted too tightly and that there is no
rolled-up sleeve exerting pressure on the arm above
the measuring position. Take off articles of clothing if
necessary.
3. Measure the blood pressure again in complete peace
and quiet.
Every measurement results in different values
although the device functions normally and the
values displayed.
• Please read the following information and the points
listed under «Common sources of error». Repeat the
measurement.
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.
