Unable to obtain a green
blinking Pulse Quality
indicator.
Low animal pulse strength, sensor
site is poorly perfused, or sensor is
not correctly positioned.
Reposition sensor on the animal.
Sensor is attached too tightly, or tape
or other items are restricting pulse
quality at sensor site.
Reapply sensor, select an
alternate sensor site, or remove
restrictive material from the
sensor site.
Circulation is reduced due to excess
pressure between the sensor and a
hard surface.
Allow sensor and sensor site to
rest comfortably on the surface.
Excessive ambient light.
Reduce ambient light.
Excessive animal motion.
Reduce animal motion.
Interference from:
• arterial catheter
• blood pressure cuff
• electrosurgical procedure
• infusion line
Reduce or eliminate interference.
Pulse Quality indicator
blinks red and the SpO
2
and/
or pulse rate displays show
dashes.
Inadequate signal at the sensor site.
Examine animal. Reposition
sensor or select an alternate
sensor site.
Excessive motion at the sensor site
may be prohibiting the device from
acquiring a consistent pulse signal.
Eliminate or reduce the cause of
the motion artifact or reposition
the sensor to a sensor site where
motion is not present.
A sensor failure.
Replace sensor.
Segments of the SpO
2
or
pulse rate displays are
missing.
Defective LED displays.
Displayed values may not be
reliable. Discontinue use of the
device.

There is a system fault that must be
corrected.
Turn the device off and on. If the
problem persists, contact Nonin
Technical Service.
Disruption in the device
performance.
Electromagnetic interference (EMI).
Remove the device from the EMI
environment.
Displays and indicators are
off, but a continuous audible
alarm is sounding.
There is a system fault that must be
corrected.
Turn device off and on. If problem
persists or device does not turn
on, replace or recharge the
batteries. If the problem persists,
contact Nonin Technical Service.
