Error Messages/Trouble-Shooting; Cleaning And Care; Technical Details - Beurer medical BM 44 Mode D'emploi

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. error messages/trouble-shooting

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 295 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
appears 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.
