If the display shows one of the follo-wing error messages, this means that the
unit was unable to accurately determine blood pressure.
Error messages
Possible causes and solutions
ERR 1
Measurement of the systolic blood pressure was completed.
Either the connection with the hose has been interrupted or no pulse could be
determined.
Check the connections between the cuff and the main unit.
ERR 2
Non-physiological pressure has been detected.
Cause: the arm was moved during the measurement.
Repeat the measurement, keeping your arm still.
ERR 3
If the cuff takes too long to inflate, it is possible that the cuff is incorrectly
positioned or that the connection with the hose is not airtight.
Check the connections and repeat the measurement.
ERR 4
The difference between systolic and diastolic pressure is abnormally high.
Repeat the measurement under relaxed conditions, following the instructions
exactly.
If the same error occurs repeatedly with further readings, please contact
MEDISANA.
ERR 5
An average value could not be calculated due to unstable conditions while the
readings were being taken.
Repeat the measuring process, keeping your arm still and not speaking.
• Remove the batteries before cleaning the unit.
• Never use strong detergents or hard brushes.
• Clean the unit with a soft cloth, moistened with mild soapy water. Do not let
water enter the unit. After cleaning, only use the unit when completely dry.
• Remove the batteries from the unit if you do not wish to use it for an
extended period of time, otherwise there is a risk of battery leakage.
• Do not expose the unit to direct sunlight, and protect it from dust and
moisture.
• Only inflate the cuff when it is in position around the upper arm.
• Servicing and calibration
The unit has been calibrated by the manufacturer for a period of two years'
use. In the case of commercial use, the unit must be serviced and recali-
brated at least once every two years. This calibration will be charged for and
can be carried out by an appropriate authority or an authorised service
centre - in accordance with the regulations for users of medical equipment.
