: No Sensor Sensor is not plugged in to the
Spectrum.
Plug the sensor into the monitor.
SpO
2
: Sensor Off
(Masimo SET
®
Only)
Sensor may not be connected to
the patient.
Check patient connection.
SpO
2
: Interference Noise detected on the pulse
signal prevents pulse
discrimination.
Decrease patient motion, check
sensor.
SpO
2
: Pulse Search Hardware settings are being
adjusted in order to discriminate
a pulse waveform.
Change to site where pulse is
stronger if patient is
vasoconstricted. Change or
readjust sensor if loose.
SpO
2
: No Pulse (Nellcor
Only)
No detectable pulse is measured Check to patient connection and
patient status.
SpO
2
: Failure The system has detected an
unrecoverable failure of the
SpO
2
system.
Power cycle unit. If message
reappears, contact Customer
Support.
SpO
2
: Low Perfusion
(Masimo SET Only)
Patient perfusion is low. Check to patient connection and
patient status.
SpO
2
: Too Much Light
(Masimo SET Only)
There is too much ambient room
light for the sensor to function
properly
Minimize the room light around
the patient. Check sensor.
SpO
2
: Unrecognized
Sensor (Masimo SET Only)
The sensor is not recognized by

2
: Board Fault Masimo SET board failed to
operate properly.
See Proper Service Menu:
Suggestion.
SpO
2
: Sensor Fault Defective Sensor. Replace Sensor.
SpO
2
: Motion (Nellcor
Only)
Motion is detected Decrease patient motion, check
sensor.
SpO
2
: Check Sensor
(Nellcor Only)
The SpO
2
module has sensed a
poor connection or a bad sensor
Reconnect the same sensor. If
problem persists, replace sensor
Unable to obtain SpO
2
reading
Patient has poor perfusion. Switch limbs / Notify physician.
Sensor not on Patient. Reapply sensor.
Cables loose / not connected. Check connections, switch cable.
Ambient light. Switch limbs and cover sensor
with opaque material.

Check sensor placement, move
as necessary.
