Possible Cause
Possible Solution
The device will not turn on.
Batteries are depleted.
Replace all 4 batteries.
Batteries are installed incorrectly.
Verify correct battery orientations.
Refer to Figure 3: Installing
Batteries.
Metal contact in battery compartment
is missing or damaged.
Contact Nonin Technical Service.
A dash appears in the left
digit of the SpO
2
display.
Sensor fault exists. Sensor may have
become dislodged from the device or
from the animal.
Verify sensor is correctly
connected to the device and the
animal. Replace sensor if
condition persists.
Dashes appear in the middle
digits for both the SpO
2
and
pulse rate displays.
No signal is detected because sensor
is not plugged in.
Verify sensor connections.
Sensor failure.
Replace sensor.
The displayed pulse rate
does not correlate to the
pulse rate displayed on the
ECG monitor.
Excessive motion at sensor site may
be prohibiting device from acquiring a
consistent pulse signal.
Eliminate or reduce the cause of
the motion artifact or reposition
the sensor to a new sensor site
where motion is not present.
Animal may have an arrhythmia
resulting in some heart beats that do
not yield a pulse quality signal at the
sensor site.
Examine animal. Condition may
persist, even though both
monitors are functioning properly,
if the animal's arrhythmia
persists.
Non-specified sensor is being used.
Replace sensor with a Nonin-
branded sensor.
ECG monitor may not be functioning
properly.
Examine animal.
Replace ECG monitor or refer to
ECG monitor operator's manual.
An erratic pulse rate display
and/or an amber Pulse
Quality indicator during the
concurrent use of
electrosurgical equipment
(ESU).
ESU may be interfering with pulse
oximeter performance.
Examine animal. Move the
device, cables, and sensors as
far away from the ESU as
possible or refer to the ESU
operator's manual.
Pulse Quality indicator
blinks amber with each
pulse.
Quality of pulse signal at sensor site is
marginal.
Examine animal. Reposition
sensor or select an alternate
sensor site.
