Preparing to measure your blood pressure
➡ Set the pressure selector switch
'DRUCKVORWAHL' to the desired cuff
pressure which should be at least 30 to
40 mmHg higher than the systolic
(upper) blood pressure reading. If you
are not sure of this value, set the selec-
tor switch to 150 mmHg for the first
measurement.
If this pressure is insufficient, the unit
will switch over to the next higher pres-
sure setting automatically.
