Navigation options

The basic structure of the site separates navigation from content and remains consistent on all pages to allow for ease of navigation.

There are two options for navigation. The main navigation bar is located at the top of the page and allows access to all the website’s main content areas. The navigation footer at the bottom of the page contains all links for top-level and second-level navigation.

Move your cursor over the main navigation bar to access drop-down menus. Use these to select the relevant topic.

Another way to find information is by typing your search term into the search bar. Further details on this can be found in the Search section below.
Further information, contact details and external links are all listed in the service navigation menu at the top right of the page.

Audio and video

The videos available on our site are hosted externally by YouTube. Due to country-specific copyright laws or companies’ own internal internet usage policies, these video site or specific videos may be blocked for some users.

Audio files can be played directly from the website in a specially provided player.


On every page of the website, you can use the search bar in the top-right corner to search for specific terms. Type the relevant keywords into the bar and then click “Search”.

The results page will show all matches.  You can then choose to refine your search by filtering the results. You can filter by content type and by media type.
Your search request is supported by the Autocomplete function, which checks your input for similar key words and generates suitable suggestions as you type. If you make a typing error or if there are no matches for your search, the system will suggest a correction to help you find the information you are looking for.
