How to install VH1 and HD for PA-80?

Hi folks, I´ve just order the PA-80. I´d like some information on the options. How can I install the hard drive and the vocal harmony? I was on a site where there was the instructional on "PDF" but I could´nt open it or transferred to my WORD in may PC. Can anyone help? Thanks a lot. Tel.

The instructions come with the Vocal board, and although it's a tight squeeze ... it's not really difficult to do it yourself. It only fits ONE way, and the instructions have pictures too. Don't be scared ..... it's made for end user installation. No soldering, no engineering .... just plug it in, screw it down and close it up !
