- rockhillmanorExplorer IIThose alarms are also hard wired to the 12 volt side of your RV.
Beeping means 'low voltage'.
Check your coach battery. - texascatsExplorerMy goodness, what a great forum site this is! To those of you who replied, I do so appreciate the advice. I didn't know CM units needed replacing. I thought it was just the batteries. Thanks again.
- aruba5erExplorerBuy a new one
They only have a 5 year life and that may include shelf life Not that expensive considering your life. Whats it worth? More than $15/18 bucks? Plus the fact that in an RV it's exposed to more CO than in a home because of the travling on the highways with all the other fuel burning stuff out there - Get a new one.
- Dennis12ExplorerIf the replaced batteries are good just remove the CM.
- Beverley_KenExplorerCheck the expiry date. Yes they du expire and will beep and alarm when its time to replace..
