Test/Reset Button
The test/reset button is used to
test the unit’s electronics and to reset
the unit during alarm
(see figure 3).
•Test the unit - To test,
press and release the test/reset button, you should
hear one short beep – followed by 5 seconds of
silence – followed by 4 short beeps with a
corresponding red LED flash. Familiarize yourself
and family members with the alarm pattern.
Test the unit weekly! If at any time your unit
does not perform as described replace it
immediately.
Note: After the test/reset button is pressed, the alarm
sounds and the red alarm light flashes. This does not
indicate that carbon monoxide is present.
Due to the loudness of the alarm we suggest you place your
fingers over the sounder opening when testing your Kidde CO
Alarm.
• Reset the unit - If the alarm is sounding, pressing
the test/reset button will terminate the alarm. If
the CO condition that caused the alert in the first
place continues, the alarm will reactivate.
Reactivation times depend on the amount of CO
that caused the CO alarm to initially alarm and the
amount of CO present after resetting the alarm
(see page 11, Alarm Instructions/Emergency
Response).

Since batteries are not installed in the unit at the factory, you
will need to install them. Your Kidde unit will continue to
remind you to change the batteries for up to seven days after
low batteries are detected.
WARNING: Your Kidde CO alarm will not be
operational and will not monitor for CO levels without
the installation of three charged AA batteries.
Your Kidde CO alarm monitors for battery failure such as
bad or corroded connections, sudden battery failure and
other causes. If the alarm senses any form of battery
failure, the unit will start chirping an audible alarm
every 30 seconds, the green and red alarm light will
flash.
The battery error warning will continue until new batter-
ies are placed in the unit, or until the remaining batteries
become completely exhausted.
Three AA batteries have been included with your pur-
chase. When replacing the batteries, we recommend use of
the following for a minimum of one year normal operation:
• Duracell MN1500 • Camelion Mignon LR6-AM3-1.5
• Energizer E91 • Rayovac LR6
These batteries can be purchased at your local retailer.
