Precautions for use
Read and follow all safety instructions before using the Wrist Oximeter.
Contraindications
DO NOT use the Wrist Oximeter in a magnetic resonance imaging (MRI) environment.
Explosion Hazard: Do not use the Wrist Oximeter in an explosive atmosphere or in the presence of
flammable anesthetics or gas.
Warnings!
General operation of the Wrist Oximeter might be affected by the presence of an electrosurgical unit
(ESU).
The wrist oximeter has no alarms. It will not sound if the amount of oximeter in your body is low or if
your pulse rate is too high or too low.
Do not use the wrist oximeter when the alarms are required！
Discontinue use of adhesive tape strips if the user exhibits an allergic reaction to the adhesive
material.
Do not place the wrist oximeter in liquid or clean it with agents containing ammonium chloride，
isopropyl alcohol，or products that are not listed in this instructions manual.
The wrist oximeter must be able to measure your pulse properly to give you an accurate reading. Do
not put the device on the same arm when using a blood pressure cuff or monitor.

Do not stretch the adhesive tape while applying the pulse oximeter sensor.
Ensure that the wrist band fits comfortably on the user’s arm. Do not over-tighten the wrist band.
Pulse oximeter readings might be affected while users are being defibrillated.
Radios and cell phones or similar devices may affect the wrist oximeter and should be kept at least 7
feet away from the device.
Use in emergency vehicles with communication systems may affect accuracy.
SpO2measurements may be adversely affected in the presence of high ambient light.
The 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.
The 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.
DO NOT use the oximeter for diagnosing or treating any illnesses.
Cautions!
Before using any sensor, carefully read the direction for use.
Do not, under any circumstance, perform any testing or maintenance on the wrist oximeter before
and after it is being used.
Verify 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.
Field strengths from fixed transmitters，such as base stations for radio (cellular/cordless) telephones
and land mobile radios，amateur radio，AM and FM radio broadcast towers and TVbroadcast towers
may affect accuracy.

If the wrist oximeter fails to respond as described, refer to “Error code”or discontinue until the
situation has been corrected by qualified personal.
Do not remove any covers other than the battery cover when replacing battery. There are no user-
serviceable parts inside.
Battery might leak or explode if used or disposed of improperly. Remove the battery if the oximeter
will be stored for more than 1 months.
Follow local governing ordinances and recycling instructions for disposal or recycling of the device
and device components including batteries.
The wrist oximeter is a precision electronic instrument and must be repaired by trained personnel
only.
The wrist oximeter measures arterial oxygen saturation of functional hemoglobin. Significant levels
of dysfunctional hemoglobin(caused by sickle cell anemia, carbon monoxide，etc.) could affect the
accuracy of the measurement.
Check the pulse oximeter sensor application site frequently to determine the positioning of the
sensor and the circulation and skin sensitivity of the user. If there is any discomfort on your
measured application，relocate the sensor to another finger.
Do not tamper with, or hang lanyard from the flexible circuit.
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.
