Cautions
This equipment complies with International Standard EN 60601-1-2:2001 for electromagnetic
compatibility for medical electrical equipment and/or systems. This standard is designed to provide reasonable protection against harmful interference in a typical medical installation. However, because of the proliferation of radio-frequency transmitting equipment and other sources
of electrical noise in healthcare and other environments, it is possible that high levels of such
interference due to close proximity or strength of a source might disrupt the performance of this
device. Medical electrical equipment needs special precautions regarding EMC, and all equipment must be installed and put into service according to the EMC information specified in this
manual.
Portable and mobile RF communications equipment can affect medical electrical equipment.
If this pulse oximetry system fails to respond as described, discontinue use until the situation is
corrected by qualified personnel.
Cardiogreen and other intravascular dyes may affect the accuracy of SpO
measurements.
The oximeter sensor might not work on cold extremities due to reduced circulation. Warm or
rub the finger to increase circulation, or reposition the sensor.
This system might misinterpret motion as good pulse quality. Minimize finger motion.
Some nail polish colors or artificial nails can reduce light transmission and affect SpO
Before using any sensor, carefully read the Directions for Use, which contain specific application
information for each sensor.
Inspect the sensor application site at least every 6 to 8 hours to ensure correct sensor
alignment and skin integrity. Pa tient sensitivity to sensors may v ary due to medical status or skin
condition.
Do not place liquids on top of this pulse oximetry system.
Do not immerse the pulse oximetry system or sensors in any liquids.
Do not use caustic or abrasive cleaning agents on the unit or sensors.

General Information about Bluetooth Technology
Bluetooth is a technology that enables automatic wireless connections between a
variety of electronic comm un icatio ns and comp uting devi ces, making it possible to
connect any compatible devices without cables or wires. The technology is based on
a radio link that offers fast and reliable transmissions of v o ic e, video, and data.
Bluetooth uses a license-free, globally available frequency range in the ISM band—
intended to ensure communication compatibility worldwide.
Nonin’s use of Bluetooth Wireless Technology allows SpO
plethysmographic data to be transmitted through a Bluetooth radio to a compatible
Bluetooth-enabled device. Nonin’s system removes the connection from the sensor
cable to the display unit, giving patients increased ability to move freely—without
being hindered by cables. Nonin’s patient module uses a class II Bluetooth radio
with a battery life of about 120 hours and a range of about 30 feet (spherical radiu s).
The display unit has a minimum ope rating battery life of 18 hours.

software is recommended). If you wish to create your own software, contact
NONIN for the data format.
NOTE: Only SpO
The memory in the system functions much like an “endless loop” tape. When the
memory fills up, the unit begins overwriting the oldest data with the new data.
Each time the system is turned on, the current time/date info rmation (if the clo ck
is set properly) is stored in memory, starting a new recording session. (See “Displays,
Indicators, and Controls” for more information about setting the clock.) Only
recording sessions greater than one minute in length are stored in memory.

Real-Time Patient Data Output
The system provides real-time data output capability via the RS232 connector port.
A null modem cable must be connected from the display unit to the receiving
computer.
The information from the system in the real-time mode is sent in an ASCII serial
format at 9600 baud with 8 data bits, no parity, and 1 stop bit. The data are output
at a rate of once per second (on separate lines).
Real-time data may be printed or displayed b y devices other than t he pulse oximet er.
Upon power up, a header is sent identifying the format and the time and date.
Thereafter, the data are sent once per second by the system in one of the following
formats:
• If DIP switch 8 is in the DOWN position, the data will be displayed as follows:
SPO2=XXX HR=YYY
where XXX is the SpO
• If DIP switch 8 is in the UP position, the data will be displayed as follows:
where XXX and YYY are the fast-responding SpO
• If there are no data from the oximeter, the formats will appear as follows:
Nonin’s Avant 4000 Digital Pulse Oximetry System includes an event marker
feature. Events are indicated by a single “*” whenever ON /STANDBY is pressed
to enter Battery Capacity Display mode. (ON/STANDBY ma y be pressed again to

Printing Options
The Avant 4000 Digital Pulse Oximetry System features printing capabilities
that allow printing on demand or in real-time. These printing options are controlled by DIP switch 4, which is found under the battery cover at the back of
the unit.
• When DIP switch 4 is in the UP position, real-time (once per second) data
output is available via the RS232 connector port, using a null modem cable.
• When DIP switch 4 is in the DOWN position (default), the Pr in t-on-Demand
mode is activated, allowing you to print only when desired.
To print displayed data on demand, press the ON/STANDBY button.
Important Notes
• Event markers are not available in Print-On-Demand mode.
• Print functions are available only with a 9600 baud serial ASCII printer.
