Hey guys. I need a little help. My maverick is a couple years old and when I went to get it going in some Canadian bacon this morning both units showed LLL. Rather than reading directions I just assumed they needed new batteries. The transmitter now reads temps and works as it should. The receiver portion still reads LLL. See below. Any thoughts in how to make this work. For now I will put the probes in the bbq and read the temps with my binoculars since it is damn cold in Wisconsin today. Any help would be appreciated since I would rather not buy a new one.
