co detector

CO detector is constantly beeping and yellow fault light is blinking.

Batteries are very good.

Any help is appreciated!

That often means that it is not fully seated on the base.  There is a "tamper switch" on the back of the unit, and a "bump" on the base.  You need to twist it past a "click" to get it fully seated and the tamper switch pushed.

Or it could just be defective.  If fully seating it does not clear the problem, call SS for troubleshooting and replacement if necessary.
