Question About Kidde Carbon Monoxide Alarm kn-cop-ic
What does err-009 mean on the red digital display ...

What does err-009 mean on the red digital display when the alarm/service light blink and the kidde carbon monoxide alarm chirps every couple of minutes. Is it the battery or something else. Could it be the connection in the back of the unit? I need to know specifically why it does those things? Model # kn-cof-ic
