In case the instrument additionally encloses CO2 sensor the meaning of the LEDs signals changes as

stated below, in the table 3.

Permanent ON

RADON < 100% • AlarmTH

CO2 < 1000ppm

Permanent ON

CO2 >= 1000ppm

Tab. 3. - LEDs signals for Smart Radon Sensor with CO2 Sensor.

The meaning of all other signals stays unchanged.
