b) Setting Threshold Value 1
If the measured CO
2
 concentration is below threshold value 1 (factory settings 800ppm),
the green LED is lit. When the CO
2
 concentration set as threshold value 1 is exceeded, the
green LED goes out and the yellow LED lights up.
Set threshold value 1 as follows:
• Briefly press the „MODE“ button repeatedly (from the normal operating mode) until
„ALARM 1“ flashes on the display.
• Briefly press the button „ENTER“; the medium display line shows the display for
threshold value 1.
• Set threshold value 1 with the arrows „“ and „“. Below 1000ppm, the step width is
50ppm, above 1000ppm it is 100ppm.
• Briefly press the „ENTER“ button to save the setting.
¼
Threshold value 1 always needs to be set lower than threshold value 2!
c) Setting Threshold Value 2
If the measured CO
2
 concentration is below threshold value 2 (factory settings 1200ppm),
the green LED is lit. When the CO
2
 concentration set as threshold value 2 is exceeded, the
yellow LED goes out and the red LED lights up. A signal sound can also be emitted (for
muting the sound signal, see chapter 9 a).
Set threshold value 2 as follows:
• Briefly press the „MODE“ button repeatedly (from the normal operating mode) until
„ALARM 2“ flashes on the display.
• Briefly press the button „ENTER“; the medium display line shows the display for
threshold value 2.
• Set threshold value 2 with the arrows „“ and „“. Below 1000ppm, the step width is
50ppm, above 1000ppm it is 100ppm.
• Briefly press the button „ENTER“ to save the setting.

Threshold value 2 always needs to be set higher than threshold value 1!
