NORMAL OPERATION
In normal operation, the alarm will blink the green LED off once approximately every
20 seconds. The display will indicate the current CO readings (if higher than 30ppm)
or three dashes (Model CD-9685).
SERVICE/TROUBLE CONDITION
Periodically, the alarm's measurement circuit is tested. If an error is detected, the
alarm will sound a double "beep" and the yellow LED will flash on twice approximately
every 40 seconds. This is an indication of circuit malfunction and that the alarm required
immediate servicing.
When AC power is lost, the green LED is off.
IF THE ALARM SOUNDS:
1. Operate the Test/Reset button to silence the alarm.
2. Call your emergency services, fire department or 911;
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.
CLEANING YOUR ALARM
You can clean the interior of your alarm by using your vacuum cleaner hose and
vacuuming through the openings around the perimeter of the alarm.
The outside can be wiped with a damp cloth. Do not use any household cleaning
agents, ammonia based cleaners, paints, varnishes or any other chemical on or near
your alarm. AFTER CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM
