Considerations1.If the product cannot be opened, Please replace a new battery, this product require AAA betteries. Make sure the battery are a high quality brand alkaline battery.2.Ito not use oximeter in places where there are anesthetic gas, oxygen, hydrogen and other flammable gases, flammable chemicals and explosive hazards, otherwise there is a risk of explosion or fire.3.In order to ensure measurement accuracy and prevent instrument failure, when using oximeter, there should be no high-voltage cable, X-ray machine, ultrasonic instrument, electrotherapy machine and other high-power equipment around. So as not to interfere with the use.4.Blood oximeter should be avoided in the too large pressure, temperature and humidity beyond the usual standard, poor ventilation, too large dust content, or there are corrosive or explosive gases and chemicals in the place of use or storage.5.If the product cannot be opened, Please replace a new battery, this product require AAA betteries. Make sure the battery are a high quality brand alkaline battery. 6.Please do not use the information displayed by oximeter as the sole basis for clinical diagnosis. Oximetry is only used as an adjuvant in diagnosis. It must be used in conjunction with the clinical manifestations and symptoms and with the doctor's diagnosis.7.When moving oximeter, it should be handled with care to avoid excessive vibration and falling.8.Please do not open the cover of oximeter by yourself. The instrument cover can only be opened by an authorized professional maintenance personnel.9.Please do not use sharp hard objects (such as pen nib, nails) for key operation, otherwise it may cause permanent damage to the surface of the key!10.Please ensure that your hands are clean.

Please do not use this product in the environment where alarm is required.13.Ensure that the battery has enough power when using it. Otherwise, startup anomalies or measurements may occur.What makes this Pulse Oximeter outstanding among the others?1.Bluetooth Pulse oximeter can be accurate and reliable measure including Blood oxygen level(Spo2), heart rate(PR) and perfusion index(PI). This is one of the most important parameters to monitor ICU patients, and it must be highly accurate, stable and intolerable to mistake. This delicate BT pulse oximeter for personal use is crafted by this manufacturer under the hospital grade at the same accuracy & stability level.2.“All-in-one” integrated portable instrument, small in volume, light in weight, easy to carry, and convenient to use. Measured in anytime, anywhere. Insert your fingertip into the instrument, the device runs automatically when you wear it. And can get readings result in just 5 seconds on the large LED display.
