Troubleshooting

Note:

 If these solutions do not correct the problem with your device, please contact Nonin Technical 

Service at (800) 356-8874 (USA and Canada), +1 (763) 553-9968, or +31 (0)13 - 79 99 040 (Europe).

Pulse Quality LED does not 
blink green.

Inadequate pulse signal

or

the sensor site is poorly perfused

or

the sensor is not correctly positioned.

Reposition the sensor.

The sensor is restricting blood 
circulation at the sensor site.

Remove the restriction to increase 
blood circulation at the sensor site 

or

 relocate the sensor.

Circulation is reduced due to excess 
pressure between the sensor and a 
hard surface.

Allow the sensor and the application 
site to rest comfortably on the 
surface.

Excessive ambient light.

Reduce ambient light.

Excessive patient motion.

Reduce patient motion.

The patient is wearing nail polish or 
artificial nails.

Remove nail polish or artificial nails.

Performance degradation from:
• arterial catheter
• blood pressure cuff
• infusion line.

Reduce or eliminate the source.

The Pulse Quality display is 
blinking red and the SpO

2

 and/

or Pulse Rate displays are 
dashes.

Inadequate pulse signal at sensor site.

Assess the patient. Reposition 
sensor 

or

 select an alternate sensor 

site.

Inadequate pulse signal due to 
excessive motion.

Reduce patient motion. Reposition 

or

 relocate the sensor.

SpO

2 

Sensor failure.

Replace the SpO

2 

sensor.

Numeric display segments are 
missing.

Defective LEDs.

Discontinue use of the device.

The lower CO

2

 bar is not 

illuminated.

The CO

2

 sensor is not plugged in.

Plug the CO

2

 sensor in.

Only the third and sixth CO

2

 

bars are illuminated.

The CO

2

 sensor has become 

disconnected.

Reconnect the CO

2

 sensor.

The airway adapter tube is not 
connected to the CO

2

 sensor.

Verify that the airway adapter tube is 
connected, with windows toward the 
sensor.

The light path is blocked.

Replace the airway adapter tube.

The CO

2

 sensor lamp is burned out.

Replace the CO

2

 sensor.

Degradation of device 
performance.

Electromagnetic interference (EMI).

Remove the device from the EMI 
environment.
