Perfusion may be too low for the N-560 to track the pulse. Check
the patient. Test the N-560 on someone else. Change the sensor
site. Try another type of sensor.

•
Electromagnetic interference may be preventing the N-560 from
tracking the pulse. Remove the source of interference (e.g.,
isolate the electromagnetic source or stabilize the sensor site). See
the caution in the EMI (Electro-magnetic Interference) section on
page 79.
•
The sensor may be too tight, there may be excessive ambient
light, or the sensor may be on an extremity with a blood pressure
cuff, arterial catheter, or intravascular line. Reposition the sensor,
as necessary.
