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
N-600x Operator’s Manual 1

Safety Cautions
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.

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

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.

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.

Operating the Battery
WARNING: Dispose of battery in accordance with local
requirements and regulations.
Operating on Battery Power
The N-600x monitor has an internal battery that can be used to power
the monitor during transport or when AC power is not available. A
new, fully charged battery provides at least 7 hours of monitoring
time under the following conditions:
• No audible alarms sound
• No analog or serial output devices are attached to the
N-600x
Operating the Battery
• Default display brightness setting
The monitor cannot be used when the battery is depleted unless the
monitor is connected to an AC power source. A warning message
displays and must be cleared by pressing the ALARM SILENCE
button before the monitor can be used for patient monitoring.
The pleth and blip displays include a battery fuel gauge indicator that
shows the remaining charge (operating hours). When the monitor is
fully charged, all four bars are lit on the indicator.
Caution: If the N-600x monitor is stored for a period of three
months or longer, notify service personnel to place the monitor in
"Shelf-mode" prior to storage. The monitor can be placed in
"Shelf-mode" by qualified service personnel using the procedures
indicated in the N-600x Service Manual. Recharge the battery
when it has not been charged for three or more months.
N-600x Operator’s Manual 27
Operating the Battery
Caution: Replace the battery if fewer than four bars are lit after
fully charging the battery. To charge a low or fully depleted
battery, connect the monitor to AC power outlet. A full charge of
a fully depleted battery takes 8 hours to charge while the monitor
is turned off. A full charge of a fully depleted battery takes 12
hours while the monitor is in the normal operating mode.
Caution: If the monitor is operated on an AC power source with a
depleted battery and the AC power is subsequently lost, the
monitor will shut down immediately.
When all of the following conditions are present for 15 minutes, the
N-600x automatically shuts down:
• Monitor is running on battery power
• No buttons have been pressed
• No pulse has been detected (for example, when a patient
is not connected to the O
XIMAX sensor or the OXIMAX
sensor is disconnected from the monitor)
• No alarms are present (other than low battery or a
non-correctable error)
Note:Whenever the monitor is connected to AC power source, the
battery is being charged. We recommend the monitor remain
connected to an AC power source when not in use. This ensures a
fully-charged battery when the monitor is needed.
28 N-600x Operator’s Manual
Low Battery Indicator
The Low Battery Indicator lights and a low priority alarm begins to
sound when approximately 15 minutes of monitoring time is
available on the existing battery charge. Refer to Table 4 for a
description of the low and critical battery conditions.
A low battery audible alarm can be cancelled by pressing the
ALARM SILENCE button. The low battery indicator and display
screen message continues to display. Connecting the monitor to an
AC power source silences the audible alarm, but the low battery
indicator remains lit as long as the battery is in the low voltage
condition. After the 15-minute period of low battery condition, a high
priority alarm sounds for about 10 seconds before the monitor shuts
off.
If the monitor backlight is turned off during a low battery condition,
the backlight cannot be turned back on.
Operating the Battery
Nellcor recommends that a qualified service personnel replace the
internal battery every 24 months. Replaced batteries should be
disposed of in accordance with local ordinances.
Caution: The pulse oximeter default settings will return to
factory default setting if the battery becomes fully discharged or
is replaced. Qualified service personnel will have to reset the
institutional defaults, following the instructions in the
N-600x Service Manual.
Note: If the AC voltage selector switch on the monitor rear panel
does not match your AC voltage source, the monitor may run on
battery power, even though it is connected to an AC power source,
which eventually results in a low priority alarm and a lighted low
battery indicator. Ensure that the switch setting matches your AC
voltage.
Note: As the battery is used and recharged over time, the amount of
time between the onset of the low battery alarm and the instrument
shut-off may become shorter.

Turning On the Monitor
Before using the monitor in a clinical setting, verify the monitor is
safe and working properly. Proper working condition is verified each
time the N-600x is turned on as described in the following procedure.
Caution: If any indicator or display element does not light when
the pulse oximeter is turned on, do not use the pulse oximeter.
Instead, contact qualified service personnel, your local Nellcor
representative, or Nellcor’s Technical Services Department.
Note: Physiological conditions, medical procedures, or external
agents that may interfere with the monitor’s ability to detect and
display measurements, include dysfunctional hemoglobin, arterial
dyes, low perfusion, dark pigment, and externally applied coloring
agents such as nail polish, dye, or pigmented cream.
Note: The monitor automatically launches the Power-On Self-Test
(POST), which tests the monitor circuitry and functions.
Using the Monitor
Caution: During POST (immediately after power-up), confirm
that all indicators light, all display segments turn on, and the
pulse oximeter speaker sounds a sequence of three ascending
tones. After the POST process complete, verify that a single onesecond tone sounds.
1. Turn on the monitor by pressing the ON/STANDBY button.
2. Ensure all of the front panel indicators illuminate.
N-600x Operator’s Manual 43
Using the Monitor
3. Once the display test portion of POST completes, the software
version displays for approximately five seconds and a sequence
of three ascending tones sound.
Note:The software version shown above is only a sample. Check your
monitor for the current software version installed.
The software version is often needed when calling Nellcor’s
Technical Services Department or your local Nellcor representative
for technical assistance. Record the software version number and
have it available prior to contacting technical assistance.
4. If the monitor detects an internal problem during the POST
process, an error tone sounds and the monitor displays an error
code (EEE) and the corresponding number (see Troubleshooting
on page 139).
5. Upon successful completion of the POST, the monitor sounds a
one-second tone indicating the monitor has passed the test.
44 N-600x Operator’s Manual
WARNING: If you do not hear the POST pass tone, do not use
the pulse oximeter.
WARNING: Ensure the speaker is clear of any obstructions.
Failure to do so could result in an inaudible alarm tone.
Note:In addition to serving as the POST pass verification, the POST
pass tone also functions as an audible confirmation that the speaker is
performing properly. If the speaker does not function, the alarm
warning sounds cannot be heard.
OXIMAX Sensor Attached
WARNING: Do not use any other cables to extend the length of
the DOC-10 Pulse Oximetry Cable. Increasing the length of the
DOC-10 cable will degrade signal quality and may lead to
inaccurate measurements.
Using the Monitor
When an O
XIMAX sensor is connected to the monitor, a “SENSOR
TYPE: . . .” message is displayed 4 to 6 seconds at the bottom of the
monitor display. The message identifies the type (model) of O
XIMAX

2, pulse rate, or
both. Trend data is stored at 2- or 4-second intervals and linked to the
response mode. When the TREND softkey is pressed, “READING
TRENDS” displays at the bottom of the N-600x screen, indicating
that the monitor is formatting the trend data to be displayed.
N-600x Operator’s Manual 73
Using Monitor Trend Data
The monitor stores up to 48 hours of 4-second trend data or 24 hours
of 2-second trend data. The amount of trend data displayed on the
screen is determined by using the ZOOM softkey. The settings
available are 20 and 40 seconds, 15 or 30 minutes, and 1, 2, 4, 8, 12,
24, 36, or 48 hours. All trend data are displayed in a graphical format
except the 20 and 40 second trend displays, which are shown in
tabular format.
The trend display can be viewed throughout the 48 hours of trend
data. Selecting the 1-hour trend display allows you to view one hour
of trend information. By using the scrolling feature, any one hour of
trend data can be viewed up the 48 hours of trend information. The
ADJUST DOWN button scrolls the display to the left and the
ADJUST UP button scrolls the display to the right.
When the data displays, the most recent readings are on the right side
of the graph. The numbers below %SpO
2 indicate the highest and
lowest parameter values at the cursor position (vertical dotted line on
the display). See Table 7.
Trend data is further explained in Specifications on page 177.
Trend data information may be retrieved through the N-600x data
port or cleared using options available in a display menu.
Caution: Monitor trend data will be lost if the main battery fails
or is removed.

Storing Trend Data
Using Monitor Trend Data
Whenever the N-600x is turned on, it stores the monitor %SpO2 and
pulse rate readings in memory every 2- or 4-seconds (regardless of
whether the N-600x is monitoring a patient or not). The N-600x can
store up to 48 hours of 4-second trend data or 24 hours of 2-second
trend data. The 48/24 hours of stored trend data can be downloaded to
a printer or a portable computer. Up to 50 alarm limit changes can be
stored in the trend data. If more than 50 alarm limit changes occur
during the 48/24 hours of trend data collection, the additional alarm
limit changes will take space reserved for trend data.
Caution: Changing alarm limit settings uses up trend memory
space. Change alarm limits only as needed.
Note: Trend memory always contains the most recent 48 hours of
data, with newly collected data overwriting the oldest data on a
rolling basis. The N-600x continues to record data points as long as
the monitor is powered on, with “blank” data points collected if no
O
XIMAX sensor is connected to the monitor or patient. “Blank” data
overwrites older patient data if the memory becomes full. Therefore,
if you want to save old patient data, it is important that you turn your
monitor off when you are not monitoring a patient, and that you
download the trend memory before it fills up and overwrites the old
data with new data (or “blank” data).

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.
The adhesive O
XIMAX sensors are capable of storing patient alarm
event data. A sensor event record allows alarm event history to travel
with the patient on the sensor’s memory chip for quick assessment at
every point of care where O
XIMAX monitors are used.
Patient (alarm event) data is stored on the memory chip of adhesive
O
XIMAX sensors (single-patient-use OXIMAX sensors only). The alarm
event data is stored (recorded) with the limit/threshold settings that
were active at the time of the event on the recording monitor. These
events can be viewed on the next O
XIMAX sensor monitor when the
patient moves to a new point of care.
An event occurs when the %SpO
2 value exceeds either the upper or
lower alarm limit for at least 15 seconds. Alarm events are grouped
and recorded to the memory chip every 5 minutes. The maximum
number of events that can be stored in an O
XIMAX sensor is typically
100.
N-600x Operator’s Manual 85
Using OXIMAX Sensor Event Records
Event records can only be viewed after an OXIMAX sensor containing
patient alarm data (event records) has been connected to an O
monitor with SENSOR enabled. Event records are designed to view
patient events from prior areas of care or transport (history) while
monitor trend should be used to view data or events from a patient
currently being monitored.
The monitor’s SENSOR EVENT RECORD indicator lights when an
O
XIMAX sensor containing event data is connected to the OXIMAX

Patient alarm event data is accessed by pressing the TREND softkey
on the main menu and selecting the SENSOR softkey option. Sensor
event record can be viewed in graphical form (GRAPH) or in a
summary table (TABLE).
