This CO detector is not a replacement for the correct installation, use and periodic
maintenance of combustion equipment, nor adequate ventilation of spaces in which these
devices are being used.
We recommend you to weekly test the CO detector using the “TEST/MENU” button on the
CO detector.
This CO detector only sounds the alarm when carbon monoxide is present at its sensor.
Therefore, it’s possible for carbon monoxide to be present elsewhere and the alarm doesn’t
sound.
When the alarm sounds, possible harmful carbon monoxide levels are present!
Carbon monoxide can be deadly!

LED will illuminate, 4 beep tones are emitted
continuously and the display will illuminate. When the carbon monoxide concentration drops below
40PPM, the alarm will stop.
What to do when the alarm sounds:
1. Open doors and windows and immediately do outside into the fresh air. Check whether
everybody has left the building.
2. Call an official installer to inspect the correct functioning and state of maintenance of the
combustion source (gas or oil powered equipment) that could be the cause for the CO
alarm.
3. Only enter the building again after the cause has been resolved and the building has been
well ventilated.
The alarm sound can be switched off by pressing the TEST/MENU button (<150PPM).
If the CO concentration drops, the alarm will eventually stop automatically.
