2.The device might misinterpret excessive movement as good pulse strength. Limit
nger movement as much as possible when using the device.
3.Do not use the device on the same hand/arm when using a blood pressure cu or
monitor.
4.The device has no alarms of blood oxygen saturation and pulse rate, and it will not
sound if the amount of oxygen in your blood is too low or your pulse rate is
abnormal.
If the measurement of SpO2 and pulse rate is not in the normal range, please
contact your health care professional.
5.Do not place the device in liquid or clean it with agents containing ammonium
chloride or products that are not listed in this Operation Manual.
6.Any of the following conditions may reduce the performance of the device:
a)Flickering or very bright light;
b)Excessive Movement;
c)Weak pulse quality (low perfusion);
d)Low hemoglobin;
e)Nail polish, and/or arti cial nails;
f)Any tests recently performed on you that required an injection of intravascular dyes
7. The device may not work if you have poor circulation. Rub your nger to increase
circulation, or place the device on another nger.
8.The device measures oxygen saturation of functional hemoglobin. High levels of
dysfunctional hemoglobin (caused by sickle cell anemia, carbon monoxide, etc.)
could a ect the accuracy of the measurements.
9.Do not use the device in a combustible environment (oxygen enriched environ
ment).
10.Do not use the device outside the speci ed operating temperature range, and do
not store the device outside the speci ed storage temperature ranges
