Safety Information
Safety Warnings
Warnings are identified by the WARNING symbol shown above.
Warnings alert you to potential serious outcomes (death, injury, or
adverse events) to the patient or user.
WARNING: The sensor extrapolates from the date and time
provided by the N-600x when recording the sensor event record
to the sensor . The accuracy of th e date/time is the responsibility of
the N-600x. It is recommended that the N-600x user set the time/
date to the correct value before a sensor event record-enabled
sensor is connected, and that this date/time not be changed while
the sensor remains connected. Since a sensor with sensor event
record data can be transported from one monitor to another,
having discrepancies in the date/time between monitors and the
sensor event record data will affect the order the sensor event
record data appears. To eliminate this possible problem, all
monitors within an institution should be set to the same time.

Safety Information
Cautions are identified by the CAUTION symbol shown above.
Cautions alert you to exercise care necessary for the safe and effective
use of the N-600x pulse oximeter.
Caution: When connecting the N-600x to any instrument, verify
proper operation before clinical use. Both the N-600x and the
instrument connected to it must be connected to a grounded
outlet. Accessory equipment connected to the pulse oximeter’s
data interface must be certified according to IEC Standard 60950
for data-processing equipment or IEC Standard 60601-1 for
electromedical equipment. All combinations of equipment must
be in compliance with IEC Standard 60601-1-1 systems
requirements. Anyone who connects additional equipment to the
signal input port or signal output port (N-600x data port
connector) configures a medical system and is therefore
responsible for ensuring that the system complies with the
requirements of system standard IEC Standard 60601-1-1 and
the electromagnetic compatibility system standard IEC S tandard
60601- 1-2. The N-600x accuracy may degra de if it is connected to
secondary I/O devices when the instrument is not connected to
earth reference.
Caution: Federal law (U.S.A.) restricts this device to sale by or on
the order of a physician.
Caution: Dispose of battery in accordance with local
requirements and regulations.

Symbols, Controls, Displays and Indicators
The N-600x algorithm automatically extends the amount of data
required for measuring SpO
2 and pulse rate depending on the
measurement conditions. During normal measurement conditions the
averaging time is 6 to 7 seconds. During conditions such as those
caused by low perfusion, interference (e.g., external interference like
ambient light), or a combination of these, the N-600x algorithm
automatically extends the amount of data required beyond 7 seconds.
If the resulting dynamic averaging time exceeds 20 seconds, the pulse
search indicator is lit solid and SpO
2 and Pulse Rate will continue to
be updated every second. As these conditions extend, the amount of
data required continues to increase. If the dynamic averaging time
reaches 40 seconds, the pulse search indicator begins flashing, the
SpO
2 and pulse rate displays flash zeros indicating a loss-of-pulse
condition.
WARNING: Failure to cover the OXIMAX sensor site with opaque
material in high ambient light conditions may result in inaccurate
measurements.

flashes when the alarm silence duration has been set to Off.
Lights whenever the N-600x algorithm detects the incoming signal
quality is degraded.
Note: Degradation can be caused by ambient light, electrical noise,
electro-surgical interference, patient activity, or other causes.
An intermittently lit Interference Indicator is common during
patient monitoring, and indicates the N-600x algorithm is
dynamically adjusting the amount of data required for measuring

SpO2 or pulse rate limit violation.
Note: If a Medium Priority Alarm is not
silenced within 2 minutes by pressing the
ALARM SILENCE Key, the monitor increases
the urgency level of the audible alarm signal by
alternating a piezo tone with the primary alarm
tone. See Piezo Tone on page 20.

Low Priority Alarm
-pitched, slow-pulsing tone indicating an
Low
OXIMAX sensor disconnect, low battery, or
monitor failure.
Note: If a Low Priority Alarm is not silenced
within 2 minutes by pressing the ALARM
SILENCE Key, the monitor increases the
urgency level of the audible alarm signal by
alternating a piezo tone with the primary alarm
tone. See Piezo Tone on page 20.
Piezo Tone A high-pitched piezo tone is sounded if there is
no user response to an audible alarm, or if the
monitor detects a failure of the primary
speaker. See High, Medium, and Low Priority
Alarms in Ta ble 3.

Setting Up the Monitor
WARNING: To ensure patient safety, do not place the pulse
oximeter in any position that might cause it to fall on the patient.
WARNING: As with all medical equipment, carefully route
patient cabling to reduce the possibility of patient entanglement
or strangulation.
WARNING: Ensure that the speaker is clear of any obstruction.
Failure to do so could result in an inaudible alarm tone.
WARNING: Disconnect the N-600x and Nellcor OXIMAX sensor
from the patient during magnetic resonance imaging (MRI)
scanning. Objects containing metal can become dangerous
projectiles when subjected to the strong magnetic fields created
by MRI equipment. Also, induced currents could potentially
cause burns.
Setting Up the Monitor
WARNING: To ensure accurate performance and prevent device
failure, do not subject the N-600x to extreme moistur e, such as
direct exposure to rain. Such exposure may cause inaccurate
performance or device failure.
WARNING: Do not use an N-600x pulse oximeter, OXIMAX sensor,
cables, or connectors that appear damaged.
N-600x Operator’s Manual 21
Setting Up the Monitor
WARNING: Do not lift the pulse oximeter by the pulse oximetry
cable or power cord because the cable or cord could disconnect
from the pulse oximeter, causing the pulse oximeter to drop on
the patient.
WARNING: The N-600x is not defibrillator-proof. However, it
may remain attached to the patient during defibrillation or while
an electrosurgical unit is in use, but the readings may be
inaccurate during the defibrillation and shortly thereafter.
WARNING: In the USA, do not connect the pulse oximeter to an
electrical outlet controlled by a wall switch, because the pulse
oximeter may be accidentally turned off.
WARNING: Use only the Nellcor pulse oximetry cable DOC-10
with the N-600x pulse oximeter. Use of another pulse oximetry
cable will have an adverse effect on performance. Do not attach
any cable that is intended for computer use to the O
XIMAX sensor
port. Do not connect any device other than a Nellcor -approved
OXIMAX sensor to the OXIMAX sensor connector.
WARNING: The N-600x should not be used adjacent to or
stacked with other equipment. If adjacent or stacked use is
necessary, the N-600x should be observed to verify normal
operation in the configuration it is to be used.
Note: The monitor incorporates watchdog timers which reset the
monitor in the event of software errors.
