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 “ Hi” 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.
7. Cleaning and care
• Clean your blood pressure monitor carefully using a
slightly damp cloth only.
• Do not use any detergents or solvents.
• Never hold the instrument under water as otherwise liquid
can penetrate and damage the instrument.
• Never place any heavy objects on the instrument.
