H. Look at the fuse rating shown on the label near the fuse holder.
The required rating is different for the new voltage setting you have
just selected, change the fuse. (See Section 2.2, Step G.)
I. Reinstall the plastic shield so that all of the holes line up with
the stand-offs. Reinstall the nylon screws. DO NOT
OVERTIGHTEN THE NYLON SCREWS!
