   (PM2.5),Temperature and Humidity. it combines sensors  

   real-time monitoring of Carbon dioxide (CO2),  

   PM2.5,temperature and humidity on its display.  

   Considerations  

   Please read the instructions carefully before using this  

   device.  

   Please keep the manual handy for quick reference and  

      troubleshooting  

     Precautions   

     Avoid covering the air intake areas during use to avoid   

     inaccurate measurements.   

     Avoid use of solvents to clean the product as residual   

     fumes will skew air quality readings.   

     Avoid water or other liquids near the product to avoid   

     electrical damage.   

     Do not allow unauthorized modifica tion or repair of   

     this product.   

     Features:   

     CO2 indicator   ：   

     -Big screen display   

     -Support test variables:Carbon dioxide(CO2),PM2.5,   

     temperature and humidity   

     -Support CO2 exceeding alarm   

     -CO2 alarm threshold can be set   

     Green: 400ppm to 1000ppm   

     Yellow: 1001ppm to 2000ppm   

     Red: 2001ppm to 5000ppm   

     PM2.5 indicator:   

     Green: 0~74 ug/m³   

     Yellow: 75~299 ug/m³   

         Red: 300~999 ug/m³    

       Time setting    

       After turn on, the device auto accesses the interface    

       which can show CO2 current value, PM2.5,    

       temperature, humidity, and time. In this state, when you    

       long-press set button, the digits of hour will flash, press    

       up button to increase digits or press down button to    

       decrease digits, and press set button to confirm and    

       switch to next option.    

       CO2 alarm threshold Setting    

       After setting time, the digits of CO2 will flash, then you    

       can press up button to increase CO2 alarm threshold,    

       or press down button to decrease CO2 alarm threshold.    

       (CO2 alarm threshold can be set to 800ppm, 900ppm,    

       1000ppm, 1100ppm, 1200ppm, 1300ppm, 1400ppm,    

       1500ppm, 1600ppm, 1700ppm, 1800ppm, 1900ppm,    

       2000ppm). After setting CO2 alarm threshold, press set    

       button to confirm setting.    

       Turn off/on CO2 alarm sound    

       Single press set button, to turn on/turn off the alarm    

            sound.    

         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      

           3)Drive in the screws, and pay attention to about 4mm      

                  exposed. Then hang up the device.       

             Working method       

             Under normal working conditions, we suggest don't do       

             any setting. You can test the current CO2/PM2.5 value       

             and temperature and humidity. (Factory default CO2       

             alarm threshold is 1000PPM)       

             Automatic calibration       

             During the first time use, please turn on device and keep       

             it working for more than 24 hours, the device will       

             automatically calibrate. (Do not power off and restart       

                     halfway when calibration)       

               About Charging        

               When low battery icon is displayed, the device needs to        

               be charged.        

               Insert the included or another compatible micro USB        

               charging cable into the device.        

               Attach the other end to a USB DC charger (such as a        

               smart phone charger that outputs DC 5V at >=1000mA.        

               Fully charge for at least 2-3 hours before use.        

               Avoid charging with a USB computer port which only        

               outputs 500mA.
