, “HI” is displayed.
• [– – –] is displayed for about 1 minute immediately after operation start regardless of the PM2.5
concentration.
• °C (current indoor temperature)
Displays the current room temperature in the range of 0°C to 39°C. (Steps of 1°C)
When the temperature is below 0°C, “0” is displayed. When the temperature is above
39°C, “39” is displayed.
• [– – –] is displayed for about 30 seconds immediately after operation start regardless of the indoor
temperature.
• % (current indoor humidity)
Displays the room humidity in the range of 20% to 90%. (Steps of 1%)
When the humidity level is below 20%, “20” is displayed. When the humidity level is above 90%,
“90” is displayed.
• [– – –] is displayed for about 30 seconds immediately after operation start regardless of the indoor
humidity.
AIR MONITOR indicator [white] (estimate values)
The display on the unit may
differ from that of the other
hygrometers or thermometers.
• This is because the humidity,
temperature and volume of
PM2.5 become uneven even
in the same room due to the
flow of air. Please use the
AIR MONITOR indicator as a
rough estimate.

Indicates the intensity of odours in 3 colours: Blue,
Orange and Red.
• Blue indicates that the air is clean.

• After operation is started, the lamp will light blue
for the first minute (approx.) regardless of odour
level.
• If odour intensity levels are unchanging, the sensor
may not respond even if there is a strong odour in the
air.
• The sensor may not respond to some odours such as
pet odours (excluding ammonia), garlic odour, etc.
• As odour perception varies by person, in some cases an odour
may be sensed even when the lamp is Blue.
If the odour bothers you, switch to manual airflow rate, and
select a high airflow rate.

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. Insert the power supply plug when
the air is clean (odour-free).
