Worn-out data cables may also cause inaccurate data, so if the data is used as a reference
to treat a patient, pay special attention to data cable and check it more frequently.
Do not tangle the SpO cable with the wires of ES (Electrosurgery) equipment.

Single use accessories should never be reused.
Only use SpO sensors specified by the manufacturer. Other SpO

improper performance.
Unplug the sensor from the monitor before cleaning or disinfecting to prevent sensor or
monitor from being damaged, and to prevent user under safety situation.
Alarm must be set up according to different situation of individual patient. Make sure that
audio sound can be activated when alarm occurs.
To avoid an electrical hazard, never immerse the unit in any fluid or attempt to clean it with
liquid cleaning agents. Always take out the batteries before cleaning.
If oximeter becomes accidentally wet during use, stop operation of the oximeter until all
affected components have been cleaned and permitted to dry completely. Contact your local
representative if additional information is required.
Remove the batteries from this unit or unplug the SpO
use it for a long period of time (approximately one month).
Notes:
Optical cross talk can occur when two or more sensors are located in adjoining areas. It can
be eliminated by covering each site with opaque material. Optical cross talk may adversely
affect the accuracy of the SpO readings.
2
Obstructions or dirt on the sensor's red light or detector may cause a sensor failure. Make
sure there are no obstructions and the sensor is clean.
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 SpO
readings.
Hazards arising from software errors have been minimized. Hazard analysis conforms
to meet ISO14971: 2000 and EN60601-1-4: 1996. Significant levels of dysfunctional
hemoglobin, such as carboxyhemoglogin or methhemoglobin, will spawn an affection of the
accuracy of the SpO measurement.

The pulse oximeter can monitor only one patient synchronously.
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.
All the waveforms have been uniformed.
The material of the device has no nature latex.
Inaccurate measurements may be caused by:
Significant levels of dysfunctional hemoglobin (such as carbonyl - hemoglobin or
methemoglobin);
Intravascular dyes such as indocyanine green or methylene blue;
High ambient light. Shield the sensor area if necessary;
Excessive patient movement;

High-frequency electrosurgical interference and defibrillators;
Venous pulsations;
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line;
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia;
The patient is in cardiac arrest or is in shock;
Fingernail polish or false fingernails;
Weak pulse quality (low perfusion);
Low hemoglobin;

1.5 Electromagnetism Interference

This 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.
