BATTERY INSTALLATION/REPLACEMENT
Once chirps with corresponding FAULT indicator (yellow LED)
flashing once every 40 seconds indicates that the battery is low
battery, you must replace with battery specified, please see
"8. SPECIFICATIONS
please perform the following steps:
5.1
Take down the unit from screw heads of the wall.
5.2
Open battery compartment.
5.3
Remove the old batteries and replace by new batteries.
5.4
Put the battery into the battery box.
5.5
Hook the alarm over the screw heads onto keyholes at the back
of the unit.
5.6
Test alarm using the TEST/SILENCE button, if the testing alarm is
ok, means the product can work normally.
WARNING! Use only the battery specified. Use of different
battery may have a detrimental effect on the CO alarm. A good
safety measure is to replace the battery at least once a year.
CAUTION: Please replace new 2pcs same type batteries in the
meantime.
CAUTION: Test the alarm for correct operation using the
TEST/SILENCE button, whenever the battery is replaced!

GENERAL MAINTENANCE
To keep your CO alarm in good working order, please follow these simple steps:
6.1
Verify the unit's alarm sound and indicators operation by enable the TEST/SILENCE button once a week.
6.2
Remove the unit from the wall and clean the alarm cover and vents with a soft brush attachment once a month to
remove dust and dirt.
6.3
Never use detergents or other solvents to clean the unit.
6.4
Avoid spraying air fresheners, hair spray, or other aerosols near the CO alarm.
6.5
Do not paint the unit. Paint will seal the vents and interfere with the sensor's ability to detect CO. Never attempt to
disassemble the unit or clean inside. This action will void your warranty.
6.6
As soon as possible, place the CO alarm back in its proper location to assure continuous protection from carbon
monoxide poisoning.
6.7
When household cleaning supplies or similar contaminants are used, the area should be ventilated.
WARNING! The following substances can affect the sensor and may cause false actions: methane, propane,
isobutene, isopropanol, ethylene, benzene, toluene, ethyl acetate, hydrogen sulfide, sulfur dioxides, alcohol-based
products, paints, thinner, solvents, adhesives, hair sprays, after shaves, perfumes, and some cleaning agents.
WARNING! Your CO alarm will not be operational and will not monitor for CO levels without battery.
WARNING! This apparatus is designed to protect individuals from the acute effects of carbon monoxide exposure. It
will not fully safeguard individuals with specific medical conditions. If in doubt consult a medical practitioner.

CARBON MONOXIDE (CO) OVERVIEW
7.1
Toxic effects
Carbon monoxide (CO) is a colorless, odorless, nonirritating gas classified as a chemical asphyxiant and whose toxic
action is a direct result of the hypoxia produced by a given exposure. CO is rapidly absorbed through the lungs,
diffuses across the alveolar capillary membrane, and is reversibly bound with hemoglobin as carboxyhemoglobin
(COHb) however, a minute amount is present in the plasma. The affinity of hemoglobin for CO is over 200 times its
affinity for oxygen. This reduces the oxygen carrying capacity of the blood, and influences the dissociation of
oxyhemoglobin, which further reduces the oxygen supply to the tissues. CO is chemically unchanged in the body and
is eliminated in expired air. The elimination is determined by the same factors that applied during absorption. The
half-life while breathing room air is 2h - 6,5 h depending on the initial COHb level. If the CO level in the inhaled air is
