The bar graph in the display and the scale on the unit indicate the
range of the blood pressure which has been recorded.
If the values for systolic and diastolic pressure are in two different
WHO ranges (e.g. systolic in the high-normal range and diastolic
pressure in the normal range) the graphic WHO classification on
the unit indicates the higher range (high-normal in the example
described).
6. Saving, retrieving and deleting results
• The results of each successful measurement are stored together
with date and time. With more than 60 items of measured data,
the earliest items of data measured are lost.
• To recall measurements, press the memory button M. The device
first shows the number of used memory spaces and then changes
automatically to the average of all stored measurements ( A ).
• By pressing the memory button M again, the most recent individ-
ual measurements are displayed with the date, time and graphic
WHO classification, while the blood pressure values and the pulse
are displayed in turn.
• You can clear the memory by holding down the memory button M
for 3 seconds.
7. Error messages/troubleshooting
In case of faults, the " Er _" message appears in the display.
Error messages can occur when
• Er1 or Er2 : the blood pressure values are unusually high or low,
• Er3 or Er4 : the cuff is fastened too tightly or loosely,
• Er5 : the pump pressure is higher than 300 mmHg,
• Er6 : pumping up takes longer than 3 minutes,
• Er0 , Er7 , Er8 or ErA : there is a system or unit error,
• the batteries are almost empty, the batteries must be replaced.
In the above cases, you must repeat the measurement.
Reinsert the batteries if necessary, or else replace them.
8. 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.
