Help with navigation or start page

• When you are on the navigation page, you can return to the homepage and change the language.
• If you click on "Explanations", you will see a description of the functions of the buttons in the blue button bar.
• Clicking on "Navigation" shows an overview of our brochures. If you are already familiar with our catalogue, you can directly access the desired section of the catalogue. Clicking on the pictures take you to the overview or title pages of our brochures containing general information on the products in the respective brochure. Clicking on the (underlined) hyperlinks in the text below the pictures takes you to a product overview where you can select a product via the short designation of the product; the system then displays the corresponding catalogue page showing the product.
• Clicking on "Versions" will in future display an overview of changes since the last version; this means that you will not have to search our wide-ranging catalogue for any changes that may have been made..
