Good Morning,
My Atlas model 01009M stopped transmitting several hours ago. (other sensors are fine). I removed the Atlas from it's mount and noted the red LED in the battery compartment was lit solid. I removed the lithium batteries and re-inserted them. The LED flashed twice at the 10 sec interval and stopped flashing. I tried several times, each with brand new alkalines and lithiums with same results. The LED is no longer lit nor does it flash. Prior to this, I've never had a problem with not transmitting or offline. Atlas has been running since October, 2018.
Any thoughts? Thanks.
