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:
Malfunction
The display remains empty when the instrument is 1. Check whether the batteries are
switched on although the batteries are in place.
The pressure does not rise although the pump
is running.
The device frequently fails to measure the
blood pressure values, or the values measured
are too low (too high).
Every measurement results in different values
although the device functions normally and
the values displayed.
The blood pressure values measured differ from
those measured by the doctor.
Further information
The level of blood-pressure is subject to fluctuations even with
healthy people. Important thereby is, that comparable measure-
ments always require the same conditions (Quiet conditions)!
You must consult your specialist dealer or chemist if there are tech-
nical problems with the blood-pressure instrument. Never attempt to
repair the instrument yourself!
Any unauthorised opening of the instrument invalidates all guarantee
claims!

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 neces-
sary.
3. Measure the blood pressure again
in complete peace and quiet.
