• For proper functioning, it is therefore necessary to ensure maximum
ventilation at least once a day. Otherwise, the device is using a faulty basis
for automatic calibration and an incorrect display may occur. In this case, a
restart under fresh air conditions or a manual calibration as described
below is recommended.
• Note: The product is not suitable for a location where ideal ventilation is
not possible (in permanently closed rooms).
10.2 Manual calibration of the CO
2
sensor
• For the whole calibration process, place the device outdoors. Choose a
shady and dry place. Wait 15 minutes, the device must adapt to the envi-
ronment.
• Use a pin to press the RESET button at the bottom. Wait until the normal
display appears (see point 6. “Operation”).
• Then press and hold the DOWN/CALIBRATE button for 2 seconds to enter
the manual calibration mode. The CAL symbol flashes.
• Wait approx. 20 minutes, until the normal display with a CO
2
concentra-
tion of 400 ppm (fresh air) appears. The calibration is completed and the
device returns to normal state. Now you can use the device again as usual.
• During the manual calibration operation, press the DOWN/CALIBRATE but-
ton to exit the calibration mode.
11. Care and maintenance
• Clean the device with a soft damp cloth. Do not use solvents or scouring
agents.
• Turn off the device if you do not use it. Press the POWER/LIGHT sensor
