* The sensor is calibrated at the factory and by default set to a manual calibration mode. If required, initiate the CO2 calibration by pressing the red button located at the front of sensor for at least 3 seconds.

Automatic / Manual calibration:

Open the lid of sensor compartment and choose the switch position to either automatic or manual.
In case the auto-calibration mode is used, the sensor needs to be exposed to fresh air at least once per month (at around 400ppm CO2 i.e. outside air or room with good air exchange).
