● When 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.
● Considering the probe is a sensitive device, please strictly follow the probe application
instructions.
● The malfunction of the 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.
● The 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.
● Do not touch the AC adapter with wet hands. Otherwise, you may suffer electric shock.
● The disposable accessories should not be cycled.
● Clean the probe with an H2O solution and a neutral detergent. Do not submerge the probe.
Do not use the probe in autoclave (sterilizer).
● This 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.
● Before cleaning or disinfecting the probe, unplug it from the pulse oximeter to prevent
probe or pulse oximeter from being damaged, and to protect user under safety situation.
● To 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 the AC adapter before
performing cleaning of maintenance.
● Alarm must be set up according to different situations of individual patient. Make sure that
chime sound can be activated when alarm function begins to work.
Cautions:
Notes:
● Application of this device may influence the measuring accuracy in the background of
electromagnetic areas such as electro-surgery environment.
● SpO2measurements may be adversely affected in the presence of high ambient light.
Shield the probe area (with a surgical towel, for example) if necessary.
● Dyes introduced into the bloodstream, such as methylene blue, indocyanine green, indigo
carmine, and fluorescein, may adversely affect the accuracy of the SpO2reading.
● Any 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.
● Remove fingernail polish or artificial fingernails before applying SpO2probes. Fingernail
polish or artificial fingernails may lead to inaccurate SpO2readings.
● Hazards 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.
● Optical 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.

● Obstructions 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.
● The AC adapter and accessories used with the device should be complied with the
requirement of IEC60601-1.
● For routine equipment maintenance, please refer to the service procedures at the
associated section as indicated in the manual.
● As to the other concerns for attention, please carefully look through the specific chapter in
this instruction.
● Federal law restricts this device to sale by or on the order of a physician.
This pulse oximeter is designed and tested in compliance with the EMC standard, complying
with the international standard for the EMC of the electronic medical device - IEC 60601-1-2.
However, because of the proliferation of radio frequency transmitting equipment and
other sources of electrical noise in the health-care and home environments (e.g. cellular
phones, mobile two-way radios, electrical appliances), it is possible that high levels of
such interference due to close proximity or strength of a source, may result in disruption of
performance of this device.
This apparatus complies with the IEC 60601-1-2 international standard. The requirements of
this international standard are: CISPR11, GROP1, and CLASS B.

◆Only use the SpO2probes provided by manufacturer for SpO2measurements. Other
SpO2probes may cause improper performance.
◆Inaccurate measurements may be caused by:
◆Do not use the SpO2probe with exposed optical components.
◆Excessive patient movement may cause inaccurate measurements.
◆Tissue damage can be caused by incorrect application or use of the probe, for example
by wrapping the probe too tightly. Inspect the probe site to ensure skin integrity and correct
positioning and adhesion of the probe. More frequently inspection should be taken depend
on different patients if necessary.
Fig.5-1 Placement of the probe
CHAPTER 5 Take a Measurement
Before taking a measurement:
Note: If there is no finger in the probe, “Finger Out!!” will be shown.
Warnings!
◆The measurement would not be performed if the following instances come across in operation:
• Shock
• Low temperature of hand
• Have taken vascular activity medicine
• Anemia
• carboxyhemoglobin
• methemoglobin
• methylene blue
• Indigo carmine
● Select the suitable probe in terms of type and dimension.
● Plug probe into SpO2socket on top panel of pulse oximeter.
● Clip the patient finger to the rational position of the probe as the illustration as Fig.5-1.
• Incorrect application or use of probe
• Significant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or methemoglobin)
• Intravascular dyes such as indocyanine green or methylene blue
• Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon
light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight

◆Loss of pulse signal can occur in any of the following situations:
• Placement of a probe on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line.
• The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
• There is arterial occlusion proximal to the probe
• The patient is in cardiac arrest or shock
• The probe is too tight
• There is excessive illumination from light sources such as a surgical lamp, a bilirubin
lamp, or sunlight
• A blood pressure cuff is inflated on the same extremity as the one to which an SpO2
probe is attached

ALARM PRIORITY:
There are three-level priorities for selection.
High priority: indicates the patient is in a dangerous situation.
Medium priority: indicates the warnings should be paid attention to.
Low priority: indicates the technical alarm caused by the device itself.
Alarms of the pulse oximeter include technical and physiological alarms. All the three priorities
are divided by built-in module and can not be changed by user.
Warnings!
When an alarm occurs, check patients’ conditions immediately.
● Check the parameter which is alarming.
● Check patient’s condition.
● Search for the source of the alarm.
● Make the alarm mute if necessary.
● Check the alarm when no warning.
