4.2 Aliarmo funkcija
The detector is equipped with both audible and visual alarms to alert you to dangerous CO levels.
- Garsinis signalas: An 85 dB alarm will sound when CO levels exceed safe thresholds.
- Vaizdinis signalas: The screen will display a high CO PPM reading, and an alarm icon will activate.
Pavojaus signalo atveju:
- Immediately move to fresh air outdoors or open doors/windows to ventilate the area.
- Negrįžkite į patalpas, kol signalizacija neišsijungs ir patalpa nebus kruopščiai išvėdinta.
- Contact emergency services or a qualified technician to investigate the source of the carbon monoxide.

6. Problemų sprendimas
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| No display/Device not turning on | Not properly plugged in; Power outage; Battery fully depleted. | Ensure the device is securely plugged into a live outlet. Check household power. Allow time for the backup battery to charge if it was fully depleted. |
| Alarm sounds without visible CO source | Actual CO presence; Sensor malfunction; Dust/debris in sensor. | Evacuate and ventilate immediately. Do not assume it's a false alarm. If confirmed false, clean the detector and re-test. If problem persists, contact support. |
| Low battery warning (when plugged in) | Faulty outlet; Battery issue; Device malfunction. | Try plugging into a different working outlet. Ensure the outlet provides consistent power. If the issue persists, the internal battery may need servicing or the unit may be faulty. Contact customer support. |
| Netikslūs temperatūros / drėgmės rodmenys | Placement near heat/cold sources; Sensor obstruction. | Relocate the detector away from direct sunlight, heating/cooling vents, or areas with extreme temperature fluctuations. Ensure air vents are clear. |
