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 pres-
sure reading. If you are not sure of this value, set the sel-
ector switch to 150 mmHg for the first measurement.
If this pressure is insufficient, the unit will switch over to
the next higher pressure setting automatically.
