MAINTENACE:
To keep your CO detector in proper working order, please follow these easy steps:
• Once a month, check that the alarm is working properly by pressing the test button.
• Clean the CO detector with a vacuum cleaner or with a soft cloth or brush once every month to remove excess dust.
• Check whether the batteries are damaged, exhausted or corroded.
• Explain to children that they should not play with the CO detector.
• Ensure children are aware of the dangers of carbon monoxide poisoning.
• Never use cleaning agents or other solutions to clean the CO detector.
• Never use air fresheners, hair spray or other aerosols near the CO detector.
• Don’t paint the CO detector. Paint covers the vents preventing the sensor from detecting CO.
• Never disassemble, repair or modify the product yourself; there’s a high risk that it will no longer function correctly or
reliably.
BATTERY REPLACEMENT
Remove the battery cover on the back of the unit by sliding the cover off the product, you will now have access to the
batteries.
Remove the batteries from the unit and replace them with 3x new High Energy Alkaline batteries 1,5V AA - LR6, making
sure that the battery polarity matches the instructions in the battery compartment.
SENSOR REPLACEMENT:
The sensor has a lifetime of 10 years. After 10 years you need to replace the complete product, the sensor itself is not
