CHAPTER 4: TESTING AND MAINTENANCE
WEEKLY TESTING
Push and hold the Test/Silence button until a loud
alarm sounds— 4 beeps, pause, 4 beeps. This
sequence should last for 10 seconds. If the Alarm ever
fails to test properly, replace it immediately. If the Alarm
is not working properly, refer to “Limited Warranty”.
•
Test/Silence button is the only proper way to
test the CO Alarm. NEVER use vehicle exhaust!
Exhaust may cause permanent damage and
voids your warranty.
• DO NOT stand close to the Alarm when the
horn is sounding. Exposure at close range
may be harmful to your hearing. When test-
ing, step away when horn starts sounding.

To keep the CO Alarm in good working order:
• Test it every week using the Test/Silence button.
• Vacuum the CO Alarm cover at least twice a
year, using the soft brush attachment. Test the
alarm again after vacuuming.
Household cleaners, aerosol chemicals and other con-
taminants can affect sensor. When using any of these
materials near Alarm, make sure room is well ventilated.
DO NOT spray cleaning chemicals or insect sprays
directly on or near the Alarm. DO NOT paint over the
Alarm, this may permanently damage the Alarm. DO
NOT expose the Alarm to strong fumes such as
painting or fumigat
ing.
THE LOW (OR MISSING) BATTERY WARNING:
NOTE: You should replace the battery immediately to
continue your protection.
LOW BATTERY SILENCE FEATURE. If AC power is on,
press the Test/Silence button to silence the low battery
“chirp” for up to 8 hours. The alarm will continue to
operate as long as AC power is supplied. However,
replace the battery as soon as possible, to maintain
protection in event of a power outage.
Choosing a replacement battery: This unit requires
one standard 9V alkaline battery. The following alkaline
batteries are acceptable as replacements. This list sup-
plements the list on the carbon monoxide alarm battery
door: Eveready #522 (Energizer); Duracell #MN1604,
MX1604 (Ultra). You may also use a Lithium battery like
an Ultralife U9VL-J for longer service between battery
changes. These batteries are available at many local
retail stores. Replacement batteries are commonly
available at local retail stores.
Use only the alkaline or lithium replacement batteries
listed. The unit may not operate properly with other
batteries. Never use rechargeable batteries since they
may not provide a constant charge.
Disconnect AC power before changing battery.
Shock hazard exists if AC power is miswired.
The horn will “chirp” once a
minute and the word “bat” will
flash on and off on the display.
