Technical alarm – description
Should the recorded blood pressure (systolic or diastolic) lie
outside the limits specified in the section “Technical speci-
fications”, the technical alarm will appear on the display
indicating either “ ” or “ Lo”. In such cases, you should seek
medical assistance and check the accuracy of your proce-
dure.
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.
10. Cleaning and storing the instrument
• Clean your blood pressure monitor carefully using a
slightly damp cloth only.
• Do not use detergents or solvents.
• On no account must you immerse the computer in water,
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.
