[Elecraft] Iambic Keying

[W4CCS]

Purchased a new Vibroplex at Dayton and having some difficulty getting 
it going. I have been using a keyboard for several years and wanted to 
maintain my sending skills (as much as they are).

With the plug inserted in the "paddle" input, All I get is a dot dash 
dot dash no matter which paddle I push. I cannot see anything in the 
config menu that addresses this problem.

Any ideas..??
