red LED will stay on. It signifies that the alarm is now in Calibration Mode.

7.12.6. After calibrating on CO gas, the 3 LEDs will flash 3 times at the same time to indicate the Calibration was sucessful.
NOTE:
1. The unit has a minimum CO concentration for calibrating (250 PPM minimum). If the calibration is carried put on a concentration
lower than 250 PPm, the unit will not change its previous calibration values.
2. When the co concentration on the lcd is bigger than 30 PPm, the unit will stop entering into calibration mode to prevent
mis-operation.
3. If the user accidentally enters into Calibration Mode by chance, just press the TEST button to exit the Calibration Mode.
7.13. When the CO Alarm raises an Alarm

8.2. To maintain your alarm in proper working order it is recommended that you:
• Test the alarm by pressing the TEST button at least once a month.
• Clean your CO alarm regularly to prevent dust build up. This can be done with a vacuum cleaner with the brush attachment once a
month. Clean gently around the grilles and sides.
