More paper shims to the rescue. Let see, I lost the cartridge that locks in the 9volt battery. Oh and the on off button doesn't work either. So I folded up two pieces of paper 7 times (it's impossible to fold paper more than 7 times, try it) and used them to wedge the battery in and easily pull it out to turn it off.
