I just grabbed my G7 br2 and its reading
E-33 ...Manuel reads ...unit isn't turning on.
Mine is dated September 2016 is it toast?

I tryed 4 different new batteries.
Man I'm bumming right now . This unit has been a great tool for me .

Any help would be greatly appreciated!!
Thank you for your time !
