middle of the channel.
Check the flow prong on the patient and the connec-
tion on the MiniScreen unit. When measuring during
CPAP therapy, check the connection of the CPAP
adapter hose on the CPAP mask and on the
MiniScreen Pro unit.
Signal amplitudes are very small or do not
appear.
Check the corresponding sensors on the patient and
their connections to the MiniScreen Pro unit. Whilst
doing so, check that the tube hoses and the black
pressure pads of the thorax sensors are intact. A
leaking sensor can cause inaccurate readings in the
thorax channel. The pressure pads should be
attached
to the patient securely without over
tightening the belt and the tube hoses should be
routed in such a way that they cannot kink.
Check all cables and connectors on the MiniScreen
Pro unit and the PC.
Pulse oximeters not responding.
The channels for oxygen saturation and pulse
frequency are registering 50% and 30 P/min respec-
tively despite the patient being connected.
First check that the finger sensor is seated correctly
on the patient and remove any nail polish that may
be present. A small red light should be present in the
sensor when the finger is inserted. If the light doesn't
switch on when the sensor is applied to the finger,
then you need to check the connection at the
MiniScreen Pro unit and any intermediate extensions.
Printout not working.
The printer prints characters on the page but in no
apparent format.
The wrong printer or printer driver has been installed.
The printer is not responding to the print command.
Check the printer cable and the connections to the
printer and PC. The printer should be switched on
and operational, i.e. the control LED’s on the printer
should be lit.
Cannot establish connection to the MiniScreen.
The USB cable is not connected correctly.
Check the connection of the USB cable to the
MiniScreen Pro and the PC.

The USB interface can be activated in the
MiniScreen Pro software. Select the "Device
connection" tab followed by menu "Settings"
.
