essary to change the setting direction if you would like to move the limits up or down.
“SPO2 ALM HI”
Here you can set an upper limit for oxygen saturation. If, during a measurement, the set limit is exceeded, the satura-
tion value appears yellow and a signal sounds (if the alarm is activated).
“SPO2 ALM LO”
Here you can set a lower limit for oxygen saturation. If, during a measurement, the set limit is undercut, the saturation
value appears yellow and a signal sounds (if the alarm is activated).
“PR ALM HI”
Here you can set an upper limit for the pulse rate. If, during a measurement, the set limit is exceeded, the pulse rate
appears yellow and a signal sounds (if the alarm is activated).
“PR ALM LO”
Here you can set a lower limit for the pulse rate. If, during a measurement, the set limit is undercut, the pulse rate ap-
pears yellow and a signal sounds (if the alarm is activated).
“Alarm”
Here you can activate (“on”) or deactivate (“o”) the alarm. If you have activated the alarm and the set upper or lower
limit is exceeded or undercut, a signal sounds.
“Pulse Sound”
Here you can activate (“on”) or deactivate (“o”) the pulse tone. If you have activated the pulse tone, a signal sounds at
every beat during the measurement.
•
To exit the alarm menu, use the function button to select the “Exit” menu item and confirm by pressing and holding down the function button.
8.4 Displaying measurement values in real time on a PC (“USB”)
Note
You can create a printout at any time during measurement
data recording by using the print function. The printout shows
the trend of the current measurement up to that point.
Note
You can view the measurement data of up to four devices at
once in the software program. In the software program, you
can enlarge the view of the individual measurement data by
selecting the corresponding measurement position number.

9. Evaluating measurement results
WARNING
The following table for evaluating your measurements does NOT
apply to people with certain pre-existing conditions (e.g. asthma,
heart failure, respiratory diseases) or whilst staying at altitudes
above 1500 metres. If you have a pre-existing condition, always
consult your doctor to evaluate your measurements.
Decline in oxygen saturation depending on altitude
Note
The following table informs you of the eects of various altitudes on oxygen
saturation value and its impact on the human body. The following table does
NOT apply to people with certain pre-existing conditions (e.g. asthma, heart
failure, respiratory diseases etc.). People with pre-existing conditions can show
signs of illness (e.g. hypoxia) at lower altitudes.
