Figure out the gas's density in the air,then mount this detector near the gas source not far than 2.5m(Note:The density of coal gas and natural gas is smaller than the air's.so they are in the higher level.LPG's density is biger  than the air's.so it is in a lower level)Make sure the power supply and signal wires are connected to the detector correctly,turn the power on,then the device will start as follows:

1.warm-up status,the red LED indicator blinks once and the speaker sounds once

2.Normal statu,the green LED indicator blinks once per minute for about 3 minutes

3.Mornitoring status,The green LED indicator is on all the time. When the density of Gas raches 6%LEL,the LED indicator will be red and blinks,the speaker will beep.(The alarm beeper frequency depends on the gas density,the higher the desity is,the higher the frequency is)
