Product questions

    Mine shows a green light on and the red light is flashing. What does this mean? No beeping, and nothing jhappens when I push the reset button.

    The green power indicator shows that the unit is powered on and the red light blinking every 3 seconds indicates it is operating properly.
    The alarm will indicate it has detected unsafe levels of CO.
    Continuous appearance of the red indicator and continuous sounding of the alarm indicates potentially dangerous levels of CO.
    Continuous appearance of the red indicator and intermittent sounding of the alarm indicates potentially dangerous levels of combustible gases.
    If the unit begins beeping once every 5 seconds or the red light is not flashing every 3 seconds there is a problem with the unit and it should be restarted by unplugging it.
