Precautions for use
Read and follow all safety instructions before using the Wrist Oximeter.
Contraindications
zDo not use the Wrist Oximeter in a magnetic resonance imaging (MRI) environment.
zExplosion Hazard: Do not use the Wrist Oximeter in an explosive atmosphere or in the
presence of flammable anesthetics or gasses.
Warnings!
zThe wrist Oximeter is intended only as an adjunct in patient assessment. It must be used
in conjunction with other methods of assessing clinical signs and symptoms.
zGeneral operation of the Wrist Oximeter might be affected by the presence of an
electrosurgical unit (ESU).
zAs with all medical equipment, carefully route patient cables and connections to reduce
the possibility of patient entanglement or strangulation.
zDo not use the wrist oximeter when the alarms are required!
zDiscontinue use of adhesive tape strips if the patient exhibits an allergic reaction to the
adhesive material

WRISTPULSEOXIMETER V2.0W1

zUse the Oximeter only within the specified temperature ranges: 5℃～40℃
humidity≤80% for operating, and -20℃~50℃humidity≤93% for storage and
transportation.
zWhen you simultaneously measure blood pressure, attach the sensor to a different
arm’s finger.
zDo not stretch the adhesive tale while applying the pulse oximeter sensor.
zEnsure that the wrist band fits comfortably on the patient’s arm. Do not over-tighten the
wrist band.
zPulse oximeter readings might be affected while patients are being defibrillated.
zDo not use the unit under conditions of shocks and vibrations. Do not use it, either, with
the patient connected to such medical electrical equipment as a cardiac pacemaker and
other electrical stimulators. And keep away from MRI, CT etc. It may cause burning and
adversely affect MRI measurement.
zSpO2measurements may be adversely affected in the presence of high ambient light.
Shield the sensor area (with a surgical towel, or direct sunlight, for example) if
necessary.
zThe device should not be used adjacent to or stacked with other equipment. If adjacent
or stacked use is necessary, the device should be observed carefully to verify normal
operation.
zThe use of accessories, sensors, and cables other than those listed in this manual may
result in increased emission and /or decreased immunity of this device.
zDO NOT USE THE OXIMETER FOR TREATMENT, we are not responsible for
contretemps happened during measuring.

Cautions!
zBefore using any sensor, carefully read the direction for use.
zDo not, under any circumstance, perform any testing or maintenance on the wrist
oximeter while it is being used to oximeter a patient.
zVerify that all visible indicators appear during the start-up (initialization) sequence. If any
indicator does not appear, do not use wrist oximeter. Contact Choice Customer support
for assistance.
zPortable and mobile RF communications equipment can affect medical electrical
equipment.
zIf the wrist oximeter fails to respond as described, refer to “Troubleshooting” or
discontinue until the situation has been corrected by qualified personal.
zDo not remove any covers other than the battery cover when replacing batteries. There
are no user- serviceable parts inside.
zBatteries might leak or explode if used or disposed of improper. Disposed of the used
batteries according to the applicable local regulations.
zFollow local governing ordinances and recycling instructions regarding disposal or
recycling of the device and device components including batteries.
zDo not immerse the wrist oximeter or sensors in water or any other liquids.
zDo not place or pour liquids on top of the wrist oximeter.
zThe wrist oximeter is a precision electronic instrument. It must be repaired by trained
Choice personnel only.
zThe wrist oximeter is designed to determine the percentage of arterial oxygen saturation
of functional hemoglobin. Significant levels of dysfunctional hemoglobin may affect the
accuracy of the measurement.

WRISTPULSEOXIMETER V2.0W1

zCheck the pulse oximeter sensor application site frequently to determine the positioning
of the sensor and the circulation and skin sensitivity of the patient. Patient sensitivity
varies depending on medical status or skin condition.
zDyes introduced into the bloodstream,such as methylene blue, indocyanine
green ,indigo carmine, patent blue (PBV), and fluorescein may adversely affect the
accuracy of the SpO2reading.
zThis device has not been tested for immunity to electromagnetic disturbances.
zSome nail polish color or artificial nails can reduce light transmission and affect SpO2
accuracy.
Warning!
DO NOT use the wrist oximeter when the alarms are required!
Unpacking and inspecting the wrist oximeter
Contact the carrier immediately if the shipping carton for the wrist oximeter is damaged.
Confirm that the items listed below are packed with the wrist oximeter:
Model MD300W wrist oximeter
Standard accessories:
zOne 1.5V AAA alkaline Battery.
zWrist oximeter instruction manual
zFinger-clip sensor
zOne reusable wristband
