Possible Solution
The device won’t turn on.
The batteries are depleted.
Replace all 6 batteries.
The batteries are installed incorrectly.
Verify battery orientation, illustrated
inside the battery compartment or on
the device label.
The Low Battery indicator is
steadily lit or flashing.
The battery level is low or critically low.
Replace all six batteries of the 9847.
An incorrect battery installation.
Verify correct battery orientation.
A dash appears in the leftmost
position of the SpO
2
display.
A SpO
2
sensor fault exists (disconnect,
failure, misalignment, or incompatibility
with the monitor).
Verify that the sensor is correctly
connected to the device and the
patient; replace sensor if the
condition persists.
A non-compatible SpO
2
sensor is being
used.
Replace the sensor with a Nonin-
branded PureLight sensor.
The middle digits display
dashes in both the SpO
2
and
pulse rate
displays.
No SpO
2
signal is detected.
Verify the sensor connection.
A sensor failure.
Replace the sensor with a Nonin-
branded PureLight sensor.
The displayed pulse rate does
not correlate to the pulse rate
displayed on the ECG monitor
when used together.
Excessive motion at the sensor site may
be prohibiting the device from detecting
a consistent pulse signal.
Eliminate or reduce the cause of the
motion
or
reposition the sensor to a
new sensor site.
The patient may have an arrhythmia
resulting in some heart beats that do not
detect a pulse quality signal at the
sensor site.
Assess the patient.
A non-compatible sensor is being used. Replace the sensor with a Nonin-
branded PureLight sensor.
The ECG monitor may not be
functioning properly.
Assess the patient.
An inconsistent Pulse Rate or
a yellow Pulse Quality display
during the use with
electrosurgical unit (ESU).
The ESU may be interfering with the
pulse oximeter performance.
Assess the patient. Move the device,
cables, and sensors as far away
from the ESU as possible.
The Pulse Quality LED is
blinking yellow with each
pulse.
The quality of the pulse signal at the
sensor site is inadequate.
Assess the patient. Reposition
sensor
or
select an alternate sensor
site.
