My Costar model 12RV-DB carbon monoxide monitor expires march 2020. I had it for nine months and now it beeps once every 30 seconds. It's seems to be a common problem with this unit. It's not a Baterry problem. I moved it outside in a well ventilated not polluted atmosphere and the problem still persist. Does Costar has a recall on this unit or a return policy?
