Remove the screw, if it has been used, that is holding the
battery door located on the bottom of the unit. Slide the
battery door in the direction of the arrows to release it.
Remove the battery and replace it with one of the
following approved replacement batteries:
Carbon-Zinc Type
Gold Peak 1604P
Alkaline Type
Energizer 522
Duracell MN1604 or MX1604
Gold Peak 1604A

These batteries can be purchased at your local retailer.
It’s recommended that the battery be replaced at least
every six months.
Replace the battery door and re-install the screw if it is
used.
NOTE: Constant exposures to high or low humidity may reduce
battery life.
To keep the CO alarm in good working order, follow
these simple steps:
• Test the CO alarm once a week by pressing the
Test/Reset button.
• Vacuum the alarm cover once a month to remove
accumulated dust. Use the soft brush attachment of the
vacuum cleaner, and unplug the CO alarm from the
electrical outlet before vacuuming.
• Instruct children never to touch, unplug or otherwise
interfere with the unit. Warn children of the dangers of
CO poisoning.
• Never use detergents or solvents to clean the CO alarm.
Chemicals can permanently damage or temporarily
contaminate the sensor.
M a i n t e n a n c e
• Avoid spraying air fresheners, hair spray, paint or other
aerosols near the CO alarm.
• Do not paint the CO alarm. Paint may seal the vents
and interfere with proper sensor operation.
• Do not mount the CO alarm directly above or near a
diaper pail.
Move the Smoke/CO Alarm to another location prior to
performing any of the following:
• Staining or stripping wood floors or furniture
• Painting or wall-papering
• Using adhesives
Storing the unit in a plastic bag during any of the above
projects will protect the sensors from damage.
WARNING: Reinstall the Smoke/CO Alarm as soon as
possible to assure continuous protection.
The following is a list of substances which, at high levels,
can affect the sensor and may cause a nuisance alarm that
is not a carbon monoxide alarm:
Methane, propane, iso-butane, ethylene, ethanol, alcohol,
iso-propanol, benzene, toluene, ethyl acetate, hydrogen,
hydrogen sulfide, sulfur dioxides, most aerosol sprays,
alcohol based products, paints, thinners, solvents,
adhesives, hair spray, after shave, perfume, auto exhaust
(cold start) and some cleaning agents.
