Problem Solution
Do not see SpO
2
 numeric area or waveform area 
on the main screen
1.   Check that the SpO
2 
is set to display in the Screen Setup menu. 
For more information, see 
27.11The Other Settings.
2. Check that if the SpO
2 
parameter switch is enabled. If not, enable 
the SpO
2
 measurement.For more information, see 3.11.1Switching 
On or Off a Parameter
.
3. Check that the cable connections of SpO
2
 sensor and the extension

sensor and the 
extension cable are tight. Replace the SpO
2
 sensor or the extension 
cable if needed.
2. Reconnect the SpO
2
 sensor if the alarm SpO2 Sensor Off appears. 
3. Check the PI value. If the PI value is too low, adjust the SpO
2
 sensor, 
or apply the sensor to the site with better perfusion.
4. Move the sensor to the place with weaker light, or cover the sensor 
with shade cloth if the alarm 
SpO2 Sensor Off appears.

2
 sensor and NIBP cuff are placed on the same limb. 
Change a monitoring site if necessary.
2. Check the PI value. If the PI value is too low. Adjust the SpO
2
 sensor, 
or apply the sensor to the site with better perfusion.
3. Check the sensor and its application site.
