Other possible errors and their solutions
If problems occur when using the device, the following points should be checked:
Malfunction
Remedy
• Check battery installation or AC adapter
connection is correct and wall outlet is work-
ing.
• If the display is blank, remove the batteries
and then exchange them for new ones.
Check polarity.
• Check the connection of the cuff tube and
connect properly.
• Ensure the cuff fits properly. (Section 5.3)
• Before starting measurement make sure
that the cuff is not too tight and that
clothing is not exerting pressure on the
arm. Take articles of clothing off if necessary.
• Measure blood pressure again in complete
peace and quiet.
• Please read the following information and
the points listed under “Common sources of
error”. (Section 5.2) Repeat the
measurement.
• Blood pressure changes constantly. The
observed readings may accurately reflect
your pressure.
• Record daily values and consult your doctor.
• Pressure readings in your doctor’s office
may be higher due to anxiety.
• Check cuff connections.
• Ensure the unit has not been tampered with.
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 values,
although the device functions normally and
normal values 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 measurement possible).
