2) Turn off: Normally, 2 minuteslater after you connect power, this status indicator will turn off directly, itmeans it already under steady working status. then, you can begin to trigger tolet it successfully programmed to alarm host panel. 
3) Flash red quickly: When it detect anygas during steady working status, it will flash quickly red 
So, if you need to program gas sensor toalarm host panel, so, please remember to wait that 2 minutes after connectingpower, only when it turn to steady working status ( Status indicator turn offas i mentioned in above point "2"), then you can begin to release gasby lighter for totally two separated times.

7. If there havesome trouble, please don't knock down and repair the alarm by yourself butnotice the supplier to repair it. 

Disposal after alarming:
When the density ofthe gas in the air gets to or exceeds the alarm set density, the alarm will gooff and keep continuous alarming, what you should do is as below: 
1.Shut off the gas bolt immediately 
2. Openthe window immediately to ventilate 
3. Crushout all fire sources and anything which may create sparks (such as lighter,match and so on)
