The display remains blank when the instru-
ment 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,
or the values measured are too low or high.
Every measurement results in different val-
ues, although the device functions normally
and normal values are displayed.
Blood pressure values differ from those
measured by my doctor.
fter the instrument has inflated the cuff
the pressure falls very slowly, or not at all.
(No reasonable measurement possible).
