        Restore it.  These are great static testers, one of the few
running around that will test leakage currents.  I got an IM-30 last
year that had the same problem with the battery compartment.  Disassemble
it, take off as much of the corrosion as you can with a stiff wire brush
(and perhaps a wire wheel on a Dremel tool), then wipe it all down with a
solution of baking soda to neutralize any remaining acid.  When dry, wipe
down with engine oil (not WD-40), then wipe clean and reassemble.

        It's worth the trouble.

        I got a manual by posting a wanted ad on the group.
