 Warm up the temperature monitoring unit for more than 20 minutes after power-on to
enable the temperature monitoring unit to reach thermal equilibrium.
 If there is no suitable indoor environment (including areas directly facing indoor and
outdoor areas, and outdoor doorways), set up a temporary passage with stable ambient
temperature for temperature monitoring.
 The factors such as sunlight, wind, cold air, and air conditioning cold and warm air can
easily affect the surface temperature of human body and the working status of the terminal,
which will cause the temperature deviation between the monitored temperature and the
actual temperature.
 Influencing factors of temperature monitoring
Wind: Wind will take away the heat from the forehead, which will affect the accuracy of 
temperature monitoring.
Sweating: Sweating is a way for the body to automatically cool down and dissipate 
heat. When the body sweats, the temperature will also decrease.
Room temperature: If the room temperature is low, the surface temperature of human 
body will decrease. If the room temperature is too high, the human body will start to
sweat, which will affect the accuracy of temperature monitoring.
The temperature monitoring unit is sensitive to light waves with a wavelength of 10um 
to 15um. Avoid using it in the sun, fluorescent light sources, air conditioning outlets,
heating, cold air outlets, and glass surfaces.
