1 Introduction
1.1 Brief Introduction
Thank you for purchasing the Hand Held Pulse Oximeter. The
device is designed to measure SpO2and PR, delivering visual
and audio alarm, sensor o alarm, data storage and review
etc. Please read this manual carefully before using it.
1.2 Safety Information
Conception of Warning, Precaution and Notice
The Warning, Precaution and Notice in this document means:
ØWarning - Indicates a potential hazard or unsafe
practice that, if not avoided, will result in death or
serious injury.
ØCaution - Indicates a potential hazard or unsafe
practice that, if not avoided, could result in minor
personal injury or product/ property damage.
ØNotice - Provides application tips or other useful
information to ensure that you get the most from
your product.
WARNINGS
• Before putting the system into operation, verify that the
equipment, connecting cables and accessories are in
correct working order and operating condition.
• To avoid explosion hazard, do not use the Oximeter in
the presence of ammable anesthetics, vapors or liquids.
• Do not open the equipment housings; electric shock

Oximeter SerieSOximeter SerieS PULSE OXIMETER INSTRUCTION MANUAL

hazard may exist. All servicing and future upgrades must
be carried out by trained personnel and authorized by
our company only.
• The Pulse Oximeter is specied for use by medical
professionals only.
• Prolonged use of the probe/sensor or the patient’s condition
may require changing the sensor site periodically. Change
the sensor site and check skin integrity, circulatory status,
and correct alignment at least every 4 hours. Prolonged use
may cause blisters, skin deterioration, and discomfort.
• When connecting this Oximeter to any instrument,
verify proper operation before clinical use. Refer to
the instrument’s user manual for full instructions. The
equipment connected to the Pulse Oximeter’s data
interface must be certied according to the respective
IEC standards, i.e., IEC950 for data processing equipment
or IEC 601-1 for medical electrical equipment. All
combinations of equipment must be in compliance with
IEC601-1-1 systems requirements.
• Sensor malfunction may cause inaccurate data, possibly
resulting in patient injury or death, so pay close
attention to the sensor and inspect it often.
• The physiological data and alarm messages displayed
on the equipment are for reference only and cannot be
directly used for diagnostic interpretation.
• Do not rely exclusively on the audible alarm system
for patient monitoring. Adjustment of alarm volume
to o may result in a hazard to the patient. Remember
that alarm settings should be customized according

Oximeter SerieSOximeter SerieS PULSE OXIMETER INSTRUCTION MANUAL
8
to dierent patient situations and always keeping the
patient under close surveillance is the most reliable way
for safe patient monitoring.
• 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 the data cable and check it more
frequently.
• When using the equipment with electrosurgical units
(ESU), make sure the patient is safe.
• Do not come into contact with the patient during
debrillation. Otherwise serious injury or death could
result.
• Single-use accessories should never be reused. To avoid
inadvertent disconnection, route all cables in a way to
prevent a stumbling hazard. Wrap and secure excess
cabling to avoid risk of entanglement or strangulation
by patients or personnel.
CAUTIONS
• Autoclaving, ethylene oxide sterilizing, or immersing the
sensors in liquid may cause inaccurate readings.
• To ensure patient safety, use only parts specied in this
manual.
• The operator must be thoroughly familiar with the
information in this manual before using the device.
• Magnetic and electrical elds are capable of interfering
with the proper performance of the equipment. For this
reason make sure that all external devices operated in
the vicinity of the equipment comply with the relevant

Oximeter SerieSOximeter SerieS PULSE OXIMETER INSTRUCTION MANUAL
9
EMC requirements. Mobile phones, X-ray equipment or
MRI devices are a possible source of interference as they
may emit higher levels of electromagnetic radiation.
• Unplug the sensor from the Oximeter before cleaning or
disinfecting it. If liquid is accidentally spilled on the unit,
clean and dry thoroughly before reuse.
• Do not try to use the SpO2and NIBP measurement on
the same arm at the same time. This could potentially
aect measurement accuracy.
• At the end of its service life, the equipment must
be disposed of in compliance with the guidelines
regulating the disposal of such products. If you have any
questions concerning disposal of the equipment, please
contact your distributor.
• Always install or carry the equipment properly to avoid
damage caused by drop, impact, strong vibration or
other mechanical force.
NOTES
• Put the equipment in a location where you can easily see
the screen and access the operating controls.
• Keep this manual in the vicinity of the equipment so that
it can be obtained conveniently when needed.
• The software was developed in compliance with
IEC60601-1-4. The possibility of hazards arising from
software errors is minimized.
• SpO2measurements may be inuenced by high ambient
light, especially sunlight. Shield the sensor area if necessary.

• Dyes introduced into the bloodstream, such as
methylene blue, indocyanine green, indigo carmine,
and uorescein, may inuence the accuracy of the SpO2
reading.
• Any condition that restricts blood ow, such as use of
a blood pressure cu or extremes in systemic vascular
resistance, may cause a failure to determine accurate
pulse rate and SpO2readings.
• Remove ngernail polish or articial ngernails before
applying SpO2sensors. Fingernail polish or articial
ngernails may cause inaccurate SpO2readings.
• 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 aect the accuracy of the SpO2readings.
• 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.
• 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 specic chapter in enclosed
instructions.
• This manual describes all features and options. This
model may not have all accessories mentioned in this
manual.
• Federal Law restricts this device to sale by or on the
order of a physician.
