In such cases, repeat the measurement. Ensure you do not
move or speak.

Technical alarm – description
Should the recorded blood pressure (systolic or diastolic) lie
outside the limits specified in the section "Technical specifica-
tions", the technical alarm will appear on the display indicat-
ing either " " or "Lo". In such cases, you should seek medical
assistance and check the accuracy of your procedure.
The limit values for the technical alarm are factory set and
cannot be adjusted or deactivated. These alarm limit val-
ues are accorded second priority under the standard
IEC 60601-1-8.
The technical alarm is a non-locking alarm and must not be
reset. The signal shown on the display will disappear auto-
matically after about 8 seconds.
