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.
