SETTING UP:

1.Open the battery cover at the back of the air quality monitor.

2.Checking the correct polarization, insert 1 x D, Mono 1.5V Alkaline battery into the battery compartment and replace the cover.

3.When the battery is inserted, all the segments of the LCD will light up briefly and a “beep” will sound.

4.Press the SET key to manually enter a time initially.

Note:

•The equivalent CO2 ppm will only be displayed after 30 minutes.

•The air quality sensor will take up to 5 days after inserting battery to condition itself for the room it is placed. If the unit is placed into another room, there might be a reconditioning time of several days as well.

INSTALLING AND REPLACING THE BATTERY IN THE AIR QUALITY MONITOR

°C/°F TEMPERATURE UNIT SETTING

The default temperature reading is set to °C (degree Celsius). To select °F (degree Fahrenheit):

1.The “°C” will be flashing, use the + key to toggle between “°C” and “°F”.

2.Confirm with the SET key to confirm all settings.

AIR QUALITY ALERT SETTING

Press and hold the ALERT button for about 3 second to enter the air quality alert setting mode, the air quality monitor has 3 alert settings (default: ALL):

2.Confirm with the SET key and the exit the manual settings.

Note:

If the air quality alert has been set to “ALL” or “LED”:

•Equivalent CO2 ppm > 1500ppm:

LED alert blinks at a slower speed (1.5s) and no alert sound.

•Equivalent CO2 ppm > 2000ppm:

LED alert blinks at faster speed (0.5s) and has alert sound. (Alert will sound only if the air quality setting has been set to ALL).

Note about the air quality alert:

•The air quality alert will sound for a maximum duration of 30 minutes. To stop the alert, press any key.

AIR QUALITY INDICATOR

The air quality indicator is located on the bottom of the LCD. It changes from GREEN to RED by measuring the Equivalent CO2 ppm.

* The air quality value shown, after sensor conditioning, may differ +/- 250 ppm.

Note:

A 9-level bar graph is used to indicate “GREEN” to “RED” air quality level in the surrounding environment:

Levels	Equivalent CO2 ppm
GREEN (level 1)	450	– 600ppm
Level 2	650	– 800ppm
Level 3	850	– 1000ppm
Level 4	1050 – 1200ppm
Level 5	1250 – 1500ppm
Level 6	1550 – 1800ppm
Level 7	1850 – 2100ppm
