indicator to display the concentration of PM2.5, the PM2.5 sensor may be
defective.

• Did an odour already exist around the time you inserted the power
supply plug?
¼ The basic sensitivity of the odour sensor will be determined by odour
levels in the first minute (approx.) after the power supply plug is inserted
every time. ►Page 10
To adjust the basic sensitivity of the odour sensor, unplug the power supply
when the air is clean (odour-free), wait at least 5 seconds, then re-insert the
power supply plug and turn the unit on again. This process adjusts the
reference odour level that determines the sensitivity of the odour sensor.

¼ Contact the place of purchase.
• Depending on the degree of air impurity, Streamer operation may turn OFF.

during ECONO MODE.

FAN setting button on the unit?
