Silencing modes
Silence: pressing the Test/Silence button when the detector is alarming, silence it for eight minutes. If the gas concentration
remains high or is becoming high again during the silence time, the detector will sound the alarm again.
Hush: pressing the Test/Silence button when the detector is in trouble situation, silence it for one hour (unless gas concentration
raises).
The LEDs
