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 the 900-0234 with digital
display:
“Lb” will be displayed alternately with the current CO reading
once every second).
To replace battery:
Remove the screw, if it has been used, that is holding the battery door
located on the back of the unit. 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 replace
the screw, if it has been used.
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.
