Reset Feature
If the alarm is sounding, pressing the button will silence the alarm for several minutes.
After the duration, if the CO condition that caused the alert continues, the alarm will
reactivate. If the CO level keeps from 70ppm to 200ppm, the duration is around 5 minutes.
If the CO level keeps over 200ppm, the duration is zero, i.e. the unit will sound soon. If the
CO level keeps below 70ppm, the unit will not reactivate longer.
Alarm Memory Feature
If you leave home for long time and during the period the unit ever alarms, after you return

You should check the possible CO source and resolve it. Pressing the button again, the
unit will return to normal condition or return to normal condition in one minute
automatically.

move away from the open door/window until the emergency services responders
have arrived, the premises have been aired out, and your alarm remains in its
normal condition.
Never restart the source of a CO problem until it has been fixed. NEVER IGNORE
THE ALARM!
The CO sensor sensitivity and setting is:
30ppm, alarms within 120 minutes
50ppm, alarms within 60~90 minutes
100ppm, alarms within 10~40 minutes
300ppm, alarms within 3 minutes
This carbon monoxide alarm is designed to detect carbon monoxide gas from ANY
source of combustion. It is not designed to detect any other gas.
Fire departments, most utility companies will perform CO inspections, some may charge
for this service.
Battery Replacement
