zThis equipment is for use in the medical field, and measurement results only serve as a
reference for any relevant treatment.
zConnect the probe correctly; please see the directions for use of any accessories.
zPlease follow the doctor’s suggestions when starting to monitor the vital sign
parameters.
zWhen connecting this device to other peripherals, make sure that you are qualified to
operate this device. Any peripheral must be certified according to the protocol of IEC
950 and IEC 601-1-1. Any input/output device should follow the protocol of IEC
601-1-1.
zConsidering the probe is a sensitive device so please strictly follow the probe
application instructions.
zThe malfunction of probe may cause inaccurate data which serves as a foundation to
treat patients, so make sure to pay more attention to the probe and inspect it usually.
zThe worn-out data cables may cause inaccurate data which is used as a reference to
treat patients, so please pay attention to the data cable and check it frequently.
zDo not touch the AC adapter with wet hands. Otherwise，You may suffer electric shock.
zThe disposable accessories should not be cycled.
zThis device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
Cautions
zClean the probe with an H2O solution and a neutral detergent. Don’t submerge the
probe. Do not use in autoclave (sterilizer).
zThis device is intended for use by persons trained in professional health care. The
operator must be thoroughly familiar with the information in this manual before using
the device.
zBefore cleaning or disinfecting the probe, unplug it from the oximeter to prevent probe
or oximeter from being damaged, and to protect user under safety situation.
zTo avoid an electrical hazard, never immerse the unit in any liquid or attempt to clean it
with liquid cleaning agents. Always disconnect the device from AC adapter before
performing cleaning of maintenance.

zApplication of this device may influence the measuring accuracy in the background of
electromagnetic areas such as electro-surgery environment.
zSpO2measurements may be adversely affected in the presence of high ambient light.
Shield the probe area (with a surgical towel, for example) if necessary.
zDyes introduced into the bloodstream, such as methylene blue, indocyanine green,
indigo carmine, and fluorescein, may adversely affect the accuracy of the SpO2
reading.
zAny condition that restricts blood flow, such as use of a blood pressure cuff or extremes
in systemic vascular resistance, may cause a failure to determine accurate pulse rate
and SpO2readings.
zRemove fingernail polish or artificial fingernails before applying SpO2probes.
Fingernail polish or artificial fingernails may lead to inaccurate SpO2readings.
zHazards arising from software errors have been minimized. Hazard analysis conforms
to meet ISO14971: 2000 and EN60601-1-4: 1996. Significant levels of dysfunctional
hemoglogins, such as carboxyhemoglogin or methhemoglobin, will spawn an affection
of the accuracy of the SpO2measurement.
zOptical cross-talk can occur when two or more probes are located in adjoining area. It
can be eliminated by covering each site with opaque material. Optical cross-talk may
adversely affect the accuracy of the SpO2readings.
zObstructions or dirt on the probe’s red light or detector may cause a probe failure. Make
sure there are no obstructions and the probe is clean.
zThe AC adapter and accessories used with the device should be complied with the
requirement of IEC60601-1.
zFor routine equipment maintenance, please refer to the service procedures at the
associated section as indicated in the manual.
zAs to the other concerns for attention, please carefully look through the specific chapter
in this instruction.

Fig.5-1 Placement of the probe
Note：If the finger is not in the probe, “Finger Out！！” will be shown.
Warnings!
zThe measurement would not be performed if the following instances come across
in operation:
zShock
zLow temperature of hand
zHave taken vascular activity medicine
zAnemia
zcarboxyhemoglobin
zmethemoglobin
zmethylene blue
zIndigo carmine
zOnly use the SpO2probes provided by manufacturer for SpO2measurements.
Other SpO2probes may cause improper performance.
zDo not use the SpO2probe with exposed optical components.
zExcessive patient movement may cause inaccurate measurements.
zTissue damage can be caused by incorrect application or use of probe, for
example by wrapping the probe too tightly. Inspect the probe site to ensure skin

V1.0M122 PULSEOXIMETEROPERATOR＇SMANUAL
15
integrity and correct positioning and adhesion of the probe. More frequently
inspection should be taken depend on different patients if necessary.
zInaccurate measurements may be caused by:
zIncorrect application or use of probe
zSignificant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or
methemoglobin)
zIntravascular dyes such as indocyanine green or methylene blue
zExposure to excessive illumination, such as surgical lamps (especially ones with a
xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or
direct sunlight
zHigh-frequency electro surgical interference and defibrillators
zVenous pulsations
zPlacement of a probe on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line.
zThe patient has hypotension, severe vasoconstriction, severe anemia, or
hypothermia
zThere is arterial occlusion proximal to the probe
zThe patient is in cardiac arrest or is in shock
zLoss of pulse signal can occur in any of the following situations:
zThe probe is too tight
zThere is excessive illumination from light sources such as a surgical lamp, a
bilirubin lamp, or sunlight
zA blood pressure cuff is inflated on the same extremity as the one to which an
SpO2probe is attached
Note：SpO2probe should obviate the light source, e.g. radial lamp or infrared lamp.
The measured results are recorded into the memory of the oximeter, and Store up to
72-hours SpO2% and Pulse rate value, the time interval is 4 seconds. When the
memory is full, a prompt window of “Space Expire!” appears. To recorded the
newest measurements, you can delete the old ones for free space.
