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, “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.
Do not disconnect the battery by pulling the battery with one hand and
the alarm with the other, as this may break the wires connecting the
battery to the CO alarm and void the warranty.
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.
