6. Error messages / Troubleshooting
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.
This situation can occur, for example, if the tube becomes unplugged after the systolic blood
pressure has been 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 reading indicated an unacceptable difference between systolic and diastolic
pressures. Take another reading following directions carefully. Contact your doctor if you con-
tinue to get unusual readings.
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 their eliminations – If problems occur when using the device, the fol-
lowing 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.
