Thanks for the useful info. I bet ya' ll are correct about the heat. I am down here in the deep south & my deer cam is on a plot, so it is in the direct heat throughout the day. I bet the heat caused it to " go blank" on the indicator screen. I will move it to a shady spot this weekend. I wanted to check out a few trails anyhow.

Thanks again. Very good info to help out a deer hunter.
