2. Segurtasun informazioa
WARNING: This device is intended to detect carbon monoxide gas. It is not a substitute for proper maintenance of fuel-burning appliances, including ventilation systems, nor is it a substitute for visual inspection of such appliances. Carbon monoxide is a colorless, odorless, and non-irritating gas that can be fatal.
- Ez blokeatu gailuko aireztapen-zuloak.
- Ez jarri gailua muturreko tenperatura edo hezetasunetara.
- Keep the device away from direct flame or heat sources.
- Do not attempt to disassemble or repair the device. Contact customer support if service is required.
- Test the device regularly as described in this manual.
Familiarize yourself with the symptoms of carbon monoxide poisoning:
- Esposizio arina: Slight headache, nausea, vomiting, fatigue (often described as 'flu-like' symptoms).
- Esposizio ertaina: Severe headache, dizziness, drowsiness, confusion.
- Muturreko Esposizioa: Inkontzientzia, konbultsioak, bihotz-arnasketa porrota, heriotza.
If the alarm sounds, immediately move to fresh air and seek medical attention. Do not re-enter the area until the source of CO has been identified and corrected, and the area has been properly ventilated.

5.4 Detektagailua probatzea
To verify the CO detection function, expose the device to a small amount of carbon monoxide. A common method is to bring it close to a lit cigarette or burning paper that produces thick smoke. The CO concentration on the screen should increase, and the alarm should activate if levels exceed the threshold. Do not test with car exhaust or in overly airy places, as low CO concentrations may not trigger the sensor.
