The sensor comes factory calibrated, but when recalibration is needed it can be done in the following steps:
1) Screw out top part of the sensor;
2) Small dipswitch on the PCB board should be set in MAN position;
3) Press and hold CALIBR. button till red LED starts to blink;
4) Now sensor should be left in the fresh air outdoor environment during the calibration process for 30 minutes without any person nearby.
5) When the calibration process is finished, screw on the sensor's top part back.
A brief video of the process can be found here.
