Detection methods                                                                            

Carbon monoxide gas from inside the space surrounding the alarm into the machine, after testing the output of carbon monoxide density, in the air just switched on, the screen display 0 to 30 PPM is normal (1 PPM = one over one million of the air volume)

1, after installed the battery, will hear a "drop" sound, red lights flashing.(for battery installed correctly)

2, when the alarm, the red light flashing quickly, and send out alarm.Restored to monitor state (carbon monoxide concentration decreases.
