Part One – Your Kidde CO Alarm
Never ignore a CO unit’s alarm. A true alarm is an indication of
potentially dangerous levels of carbon monoxide. CO alarms are
designed to alert you to the presence of carbon monoxide before
an emergency and before most people would experience symp-
toms of carbon monoxide poisoning.
How to Replace the Battery in Your Model KN-COB-LCB-A
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 batter-
ies:
•
Energizer 522
•
Duracell MN1604
•
Ultralife lithium U9VL
Replace the battery door and re-install the screw if it is used.
Any of these batteries can be purchased where you bought the
alarm or at your local hardware store.
Constant exposures to high or low humidity may reduce battery
life.
We recommend you replace your 9V battery at least every six
months.
How to Care for Your CO Alarm
To keep your CO alarm in good working order, you must follow
these simple steps:
• Test the CO alarm once a week by pressing the Test/Reset but-
ton.
• Vacuum the alarm cover once a month to remove accumulated
dust. Use the soft brush attachment of your vacuum cleaner,
and unplug the CO alarm from the electrical outlet before vac-
uuming.
• 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 contami-
nate the sensor.
• 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 inter-
fere with proper sensor operation.
