B50-70 screw size?

What is the actaul screw size? I looked over the whole manual for B50-70 and saw no mention of screw sizes for the back of B50-70. What size screw driver should I use? Can I use an electric driver to unscrew?

Back cover uses M2.5 x 5 mm screws; so you'll need a M.2 screwdriver. Here's the hardware manual you can refer to if you're planning to upgrade:
