Other possible errors and their solutions
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 batteries are in place.
The pressure does not rise although
the pump is running.
The device frequently fails to
measure blood pressure values or
the values measured are too low or
high.
Every measurement results in a dif-
ferent value, although the device
functions normally and normal val-
ues are displayed.
Blood pressure values differ from
those measured by my doctor.
After the instrument has inflated the
cuff the pressure falls very slowly, or
not at all (no reasonable measure-
ment possible).

Remedy
1. Check batteries for the correct
polarity.
2. If the display is unusual,
remove the batteries and
exchange them for new ones.
Check the connection of the cuff
tube and connect properly.
1. Check the positioning of the cuff.
2. Measure blood pressure again
in peace and quiet, carefully
following the details in Section 5.
Please read the following infor-
mation and points 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.
Record the daily development of
the measured values and consult
your doctor.
Please note: Individuals visiting
their doctor frequently experience
anxiety, which can result in a
higher reading than at home
under resting conditions.
1. Check cuff connections.
2. Ensure the unit has not been
tampered with.
