HI
The pressure in the cuff is too high (over 300 mmHg) OR the pulse is too high (over

Further Information
The level of blood-pressure is subject to fluctuations even with healthy people. Important thereby is,
that comparable
measurements always require the same conditions (Quiet conditions)!
If, in spite of observing all these factors, the fluctuations are larger than 15mmHg, and/or you
hear irregular pulse tones on several occasions, please consult your doctor. You must consult
your specialist dealer or chemist if there are technical problems with the blood-pressure
instrument. Never attempt to repair the instrument yourself! Any unauthorised opening of the
instrument invalidates all guarantee claims!
Malfunction
Remedy
The display remains empty when the
instrument is switched on although the
batteries are in place.
1. Check whether the batteries are installed with
the correct polarity and correct if necessary.
2. If the display is unusual, re-insert batteries or
exchange them.
The device frequently fails to measure
the blood pressure values, or the values
measured are too low (too high).
1. Check the positioning of the cuff.
2. Measure the blood pressure again in complete
peace and quiet under observance of the details
made under point 5.
Every measurement results in different
values although the device functions nor-
mally and the values displayed are normal.
• Please read the following information and the
points listed under «Common sources of error».
Repeat the measurement.
The blood pressure values measured differ
from those measured by the doctor.
• Record the daily development of the values and
consult your doctor about them.
