Cleaning Method:
1) Open the air quality sensor door.
2) Clean the lens and dust inlet/outlet with a lightly moistened cotton swab.
Afterwards, dry the lens and dust inlet/outlet with a dry cotton swab.
3) Close the air quality sensor door.
Note:
When the humidity level in the room is very high, it is possible that condensation develops on the
air quality sensor. As a result, the air quality light may indicate that the air quality is bad even though it is
good. In this case, you have to clean the air quality sensor on a periodically basis, i.e. every 2 months.
