Do not use the oximeter immediately after it has been transferred from a cold environment to
a warm or humid environment.
Do not press the buttons on the front panel with sharp materials. The flexible circuit connects
the two parts of the device and should not be twisted or pulled.
Remove the batteries if the device is to be stored for more than a month, otherwise leakage
may occur.
The product lanyard is made of anti-allergic material. if the lanyard causes an allergic reaction,
stop using it. Do not wear a lanyard around your neck.
The device does not have low voltage alarm function, only shows low voltage, please replace
the battery when the battery power is used up.

PRINCIPLES OF OPERATION OF THE PULSOXYMETER
The finger pulse oximeter is used to measure blood saturation, i.e. SpO2 oxygenation and pulse in
real time. It allows you to examine the level of hypoxia in the body, which is dangerous to human
health and life.
The principle of operation of the pulse oximeter is that, according to the technology of scanning and
recording capacitive pulses, it measures the radiation absorbed by red blood cells with two
wavelengths: infrared and red. Based on the measurement, using the method of transmission
spectrophotometry, it measures the differences in the optical properties of oxygenated and non-
oxygenated hemoglobin and calculates the degree of hemoglobin saturation with oxygen (SpO2).
