Guest Marie Posted April 2 Report Share Posted April 2 Our CM tester was beeping loudly so I changed the batteries and now it’s stopped. Does that mean it’s actually ok? It’s 2:30am but don’t know if we should get the kids out the house or go back to sleep??? Quote Link to post Share on other sites
green-foam 0 Posted April 7 Report Share Posted April 7 If you CO detector stops beeping after you have changed the batteries, and so long as it operates when the Test button is pressed, and it is not past its life expectancy date, all is well. Quote Link to post Share on other sites
