Your manual should show the installation and adjustment. However, Hb did not ship all units with manuals. So you can do one of two things. Ask HB for a manual, usually a disk. or ask the forum to send you a manual electronically. I think this is a PDF file type.
If you send me your email to my email, I think I have the pdf file and can send to you..
