• the pump pressure is higher than 300 mmHg (
on the display)
• pumping up takes longer than 160 seconds (
the display)
• there is a system or device error (
pears on the display)
• the batteries are almost empty
• the data could not be sent to the PC (
display).
In such cases, repeat the measurement. Ensure you do not
move or speak. If necessary, re-insert or replace the batteries.
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 indicating
either " " or " Lo Lo ". In such cases, you should seek medical as-
sistance and check the accuracy of your procedure.
The limit values for the technical alarm are factory set and can-
not be adjusted or deactivated. These alarm limit values 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 automati-
cally after about 8 seconds.
