Gas alarm is set at safety level. However, sudden release of gas will exceed the safety level
and reach to dangerous level within a short time. If the alarm is activated, leave from that
area immediately and ventilate there. Also, stop the leaking source immediately, if the gas
leak is identified.
If alarm is issued, the LCD changes to alarm indication automatically.
