Kidde KN-COB-DP-LS - Manual (Page 16)

Battery Replacement
NOTE: This CO alarm is not battery operated. However, these alarms
are equipped with 9 volt battery backup – the 9 volt battery is to supply
short term back-up during a power outage.
When replacing the battery, use one of the following approved brands:
• Duracell MN1604 or MX1604
• Energizer 522
• Gold Peak GP1604A
These batteries can be purchased where you bought the alarm or at a
local hardware store. Use of a different battery may have a detrimental
effect on the alarm operation.
The 9 volt battery is not rechargeable. If the 9 volt battery is missing,
disconnected, or if the battery’s power is low, a red LED flash will occur
once every 15 seconds, accompanied by an audible beep. If this
happens, the battery must be replaced. (For model KN-COP-DP-LS
with digital display: “Lb” will be displayed alternately with the current
CO reading once every second).
To replace battery:
If present, the screw holding the battery door will need to be removed.
Slide the battery door toward the back of the alarm to release it.
Remove the battery and replace it with one of the approved replacement
batteries. Reinstall the back door and attach the screw, if desired.
IMPORTANT: Constant exposures to high or low humidity may reduce
battery life. A good safety measure is to replace the battery at least once
a year, or at the same time as you change your clocks for daylight saving
time.
After installing or changing the battery, reinstall your alarm. Test your
alarm by using the Test/Reset button and check that the green LED is on.
Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
