Cautions
This equipment complies with International Standard EN 60601-1-2:2001 for
electromagnetic compatibility for medical electrical equipment and/or systems. This stan-
dard 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 interference due to close proximity or strength of a source
might disrupt the device's performance.
If this pulse oximetry system fails to respond as described, discontinue use until the situa-
tion 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
accuracy.
Before using any sensor, carefully read the Directions for Use, which contain specific appli-
cation information for each sensor.
Inspect the sensor application site at least every 6 to 8 hours to ensure correct sensor
alignment and skin integrity. Patient sensitivity to sensors may vary 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.
Do not gas sterilize or autoclave this pulse oximetry system.
Batteries might leak or explode if used or disposed of improperly.
Follow local governing ordinances and recycling instructions regarding disposal or recy-
cling of the device and device components, including batteries. Use only NONIN-
approved battery packs, and remove batteries if the system is not used within 30 days.
When using the 300PS-UNIV battery charger, ensure that the AC cord is plugged into a
grounded outlet.
Do not fasten the patient module too tightly around the patient's wrist. Inaccurate readings
and patient discomfort could result.
Caution: Exposure to Radio Frequency Radiation. The radiated output power of the display unit
is far below FCC radio frequency exposure limits. Nevertheless, the device must be used in
such a way that the potential for human contact during normal operation is minimized. To
avoid the possibility of exceeding FCC radio frequency exposure limits, remain at least
20cm (8 inches) away from the display unit's internal antenna during normal operation. The
wrist-worn patient module has been tested and meets allowed limits for exposure.
