The bar graph in the display and the scale on the unit in-
dicate 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. error messages/troubleshooting
In case of faults, the "Er_" message appears in the display.
Error messages can occur when
• the blood-pressure values are unusually high or low (Er1
or Er2 appears in the display),
• the cuff is too tight or too loose (Er3 or Er4 appears in the
display),
• the inflation pressure is higher than 300 mmHg (Er5 ap-
pears in the display),
• inflation takes longer than 3 minutes (Er6 appears in the
display),
• there is a system or device error (ErA, Er0, Er7 or Er8 ap-
pears in the display),
• the batteries are almost empty
In such cases, repeat the measurement. Ensure you do not
move or speak.
If necessary, re-insert or replace the batteries.

7. Cleaning and care
• Clean your blood pressure computer carefully using only a
slightly moistened cloth.
• 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.
