Installation Notes
1)The positioning sticker is attached to the position to be installed.
2)Punch a 6mm hole at the 2 marked positions of the positioning sticker and drive the rubber plug into the wall.
3)Drive in the screws, and pay attention to about 4mm exposed. Then hang the CO2 meter up.
4）Connect one end of the USB cable to the USB power adapter, and the other end （round connector）to the power input port on the side of the device(input voltage ：DC5V)
Working method:
Under normal working conditions, don't do any settings, just plug USB port to the power adapter and the DC round head into the device. You can test the current CO2 value and temperature and humidity in real time.
Automatic calibration:
During the first use, please Turn on device and keep more than 24 hours, the device will automatically calibrate.
(Do not power off and restart halfway when calibrating)
