I've just acquired a Sony WRT-8B radio mic, and I'm finding the menus a tad confusing. Does anyone have a user manual I could borrow / buy / beg? I've tried searching the web and I've emailed Sony twice - but got no reply at all so far. Can anyone help? Thanks.

Have you searched for one on-line? "WRT-8B manual"
Is this what your looking for?
