[R-390] micro switch fixed

[Scott Bauer]

 I would like to thank everybody for the help. My problem was indeed
the microswitch. I went to the Pearls Page, read the instructions and
took the front panel right off. It was much easier than I thought. It took
about 5 minutes to fix the switch and another 10 to put it back together.
5 more to take it back apart and tighten the zero adjust thingy and then
5 more minutes to put it back together again. Not too bad for a rookie.
It was a lot of fun actually. Thanks again for all of the help.
