7. Error Messages/Malfunctions

If an error occurs during a measurement, the measurement is
discontinued and a corresponding error code is displayed.
(Example: Error no. 1)
Error No. Possible cause(s)
ERR 1 The systolic pressure was determined but afterwards the cuff pressure fell below 20 mmHg.
The tube may have become unplugged after the systolic blood pressure was measured. Further
possible cause: No pulse has been detected.
ERR 2 Unnatural pressure impulses influence the measurement result. Reason: The arm was moved
during the measurement (Artefact).
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 readings indicated an unacceptable difference between systolic and diastolic
pressures. Take another reading following directions carefully. Contact you doctor if you
continue to get unusual readings.
ERR 6 Single data differ too much during MAM mode even after 4 cycles. No average result can be displayed.
HI The pressure in the cuff is too high (over 300 mmHg) OR the pulse is too high (over 200 beats
per minute). Relax for 5 minutes and repeat the measurement.*
LO The pulse is too low (less than 40 beats per minute). Repeat the measurement.*
* Please consult your doctor, if this or any other problem occurs repeatedly.
Other possible malfunctions and possible 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 empty 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
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.

Remedy
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.
• Check the connection of the cuff tube and connect properly if
necessary.
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.
• Please read the following information and the points listed
under «Common sources of error». Repeat the measurement.
• Record the daily development of the values and consult your
doctor about them.
