what the heck is a Namiki DF-100 Direction Finder


I was at salvation army (which is a sometime bountiful hunting ground for ancient audio) and I found a Namiki DF-100 Direction Finder. It's a small, blue metal box about 5 x 2 inches. On the back is Japanese writing and an a diagram of an amp and cord. There are two buttons on the front and 4 indicator lights. Anyone have any idea what this thing is? How to work it? Thanks tons

Seasoned- Would you still have a copy of the Namiki instructions that you could share with me?  I recently purchased one but the previous owner did not have the instruction sheet.
