Technical alarm – description
Should the recorded blood pressure (systolic or diastolic)
lie outside the limits specified in the section “Technical
specifications”, the technical alarm will appear on the dis-
play indicating either “ ” or “ ”. 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 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 auto-
matically after about 8 seconds.
9. Cleaning and storing the instrument

otherwise liquid can enter it and cause demage.
• When storing the device, make sure that no heavy objects
are placed on top of it. Remove the batteries. The cuff
tube should not have any sharp kinks.
