•
Start the "SpO -Manager" program on your PC.
•
Options
•
Click the magnifying glass symbol in lower section of the program. The "New Session" window opens.
•
Please enter your user data. To confi rm the user data, click "ok". The program now displays that the pulse oximeter is connected to the computer
and that the program is ready to receive the measurement data ("Device connected : wating for data ...").
•
Switch on the pulse oximeter.
•

Here you can set whether the setting value runs up or down when setting the alarm limits in the alarm menu. It is nec-
essary to change the setting direction if you would like to move the limits up or down.
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).
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).
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).
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).
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.
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.
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.

10. Maintenance/cleaning
IMPORTANT:
o not use high-pressure sterilisation on the pulse oximeter!
D
Under no circumstances should you hold the pulse oximeter under water, as this can cause liquid to enter and damage the pulse oximeter.
•
Clean the housing and the interior rubber surface with a soft cloth dampened with medical alcohol after each use.
•
If a low battery status appears on the display of the pulse oximeter, change the batteries.
•
If you are not going to use the pulse oximeter for more than one month, remove both batteries from the device to avoid possible leaking.
11. Storage
IMPORTANT:
Store the pulse oximeter in a dry place (relative humidity ≤95 %). If the humidity is too high it may shorten the service life of the pulse oximeter or dam-
age it. Store the pulse oximeter in a place where the ambient temperature is between -40°C and 60°C.
12. Disposal
Dispose of the device in accordance with Directive 2002/96/EC – WEEE ("Waste Electrical and Electronic Equipment"). If you have any queries,
