7. Maintenance
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, “Lb” will be displayed
alternately with the current CO reading once every second accompanied
by an audible beep every 15 seconds. If this happens, the battery must
be replaced.
To replace battery:
Remove back door by sliding it down and out. Remove battery by
unsnapping it from the battery clip. Install a new battery by connecting
it to the battery clip and place into the recessed battery cavity. Reinstall
the back door of the unit.
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 display 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.
• Avoid spraying air fresheners, hair spray, paint or other aerosols near
the alarm.
• Do not paint the unit. Paint will seal the vents and interfere with
proper sensor operation.
