Anyone know how to set these up? I've bought secondhand, but it came without instructions on how or why to adjust it.
Thanks.

No adjustment - just wop it on!

The instructions are in Japanese anyway ;)

If you need piccies (all there is to work from), let me know & I'll scan & send!

Thanks, that would be a great help, that way I know it's pluged in correctly.

I'll route'em out this evening. They're sitting in the attic somewhere... :)
