         Installation Notes    

         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     

               calibration)
