USING THE SILENCE FEATURE
NEVER disconnect the power to your Alarm to silence the horn—use the
Silence Feature. Disconnecting the Alarm removes your protection!
•  The Silence Feature is intended to temporarily silence the horn while 
you identify and correct the problem. 
•  To use the Silence Feature, press the Test/Silence button until the horn
is silent.
•  If the Test/Silence button is pressed while the Alarm is in the silence
mode, the alarm will start sounding again.
WHEN THE CO ALARM IS SILENCED...
The CO Alarm will remain silent for up to 4 minutes. While the Alarm is
silenced, it will continue to monitor the air for CO. After 4 minutes, if CO levels
remain potentially dangerous the horn will start sounding again.
The Silence Feature is intended to temporarily silence the Alarm horn. It will
not correct a CO problem.
IF THE CO ALARM SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the 
number of your local emergency service here:
_______________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window. 
Do a head count to check that all persons are accounted for. Do not re-
enter the premises, or move away from the open door or window until the
emergency services responder has arrived, the premises have been aired
out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour 
period, repeat steps 1-3 and call a qualified appliance technician to 
investigate for sources of CO from fuel-burning equipment and appliances,
and inspect for proper operation of this equipment. If problems are identi-
fied during this inspection have the equipment serviced immediately. Note
any combustion equipment not inspected by the technician, and consult
the manufacturers’ instructions, or contact the manufacturers directly, for
more information about CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operating in an attached 
garage or adjacent to the residence. Write down the number of a qualified
appliance technician here:

IF YOUR CO ALARM SOUNDS
WHAT TO DO IF CARBON MONOXIDE IS DETECTED
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. In other words, when your CO Alarm sounds, you
must not ignore it!
USING THE PEAK CO MEMORY
The CO Memory Feature lets you check the highest level of CO recorded.
To check CO Memory:
1. Press the Display button until the peak CO level is displayed.
To clear CO Memory:
1. While checking CO memory, press or hold the Display 
button until “CLEAR” is displayed.
2. Press or hold the Display button until the CO Memory is
cleared.
NOTE: The highest CO level will be saved, even after an AC power interruption,
until you clear it. DO NOT clear the CO Memory reading if you plan to call
someone to investigate a CO problem! Clear the CO Memory reading only
after the investigator has checked your home.
USING THE REMOTE CONTROL TEST/SILENCE FEATURE
Using the VOLUME or CHANNEL buttons on most remote controls, you can
test or silence this CO Alarm from up to 12 feet (3.6 meters) away.
To Test or Silence the Alarm:
1. Make sure you have a clear path between you and
the Alarm, free of any obstructions.
2. Point the remote at the front of the Alarm.
3. Press the VOLUME or CHANNEL button for at least 
5 seconds.
If the Alarm does not respond to your remote control:
You may be standing too far away.
Your remote may not be compatible.
You did not hold the button on your remote for at
least 5 seconds.
AC power must be present to Silence the low battery chirp.
SILENCING THE LOW BATTERY WARNING
This Silence Feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours if AC power is present. You can silence the low battery warning
“chirp” two ways:
1. Manually: Press the Test/Silence button on the Alarm cover until you see
the Green LED flicker, acknowledging the button-press.
2. Using Your Remote Control: Standing no further than 12 feet (3.6 meters)
away from the Alarm, aim your IR remote at the Alarm and press the
CHANNEL or VOLUME button for at least 3-5 seconds.
The display will flash “SILENCE” for 8 hours while the low battery warning
“chirp” silence feature is activated. After 8 hours, the low battery “chirp” will
resume. 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.
