There are sometimes problems trying to open the menus. The PDF document format is standard accross the world to help people share documents. It is not installed in Windows by default and so it needs to be installed - just once to enable viewing of PDF's.
For your convenience we have included a link opposite to the Adobe Website in order to allow you to get the PDF reader.
If you are unsure, email us or telephone and we will send you a menu by traditional means!
