Looks like Radio Shack doesn't have the full Owner's Manual for the PRO-43
online.
This may
help:http://support.radioshack.com/suppor...6/doc16688.htm
There are other PRO-43 documents on the RS Product Manuals site.Go there from

I recently bought a Radio Shack Pro-43 scanner, could someone give me
a brief idea (if that's possible) how to use it!? I already seem to
have locked out channel 2 and cannot get the unit to scan on that
channel. Any tips would be helpful, even very basic ones. I'm
completely new at this.
