If there is still problems:
(1) Ensure there are no fuel burning appliances in the vicinity which could be leaking
CO gas (e.g. even from next door).
(2) Ensure there are no fumes in the area (e.g. paint, thinners, hair spray, chemical
cleaners aerosol sprays etc).
(3) Ensure there is no outdoor source of CO in the vicinity (e.g. a car with engine
running, heavy traffic, heavy air pollution, barbecue fumes etc).
(4) Ensure there is no source of hydrogen such as batteries being charged (e.g. on
boats or in UPS’s, Uninterruptible Power Supplies).
(5) Ensure there is not excessive smoke or fumes from devices such as Egyptian
shisha , hookah or hubbly bubbly pipes, especially those that use coal or charcoal to
heat the tobacco.
(6) Press the test/hush button to silence the alarm.
If the unit continues to sound it is possibly defective and should be replaced (see
section 11 “Getting the CO Alarm Serviced”).
