Clicking on one of the PR, MR or NT buttons in the toolbar at the top of the screen will bring up a menu which will allow you to specify what you are looking for in the documentation concerned.

These menus have a common general structure.

Above all, they allow you to define your search precisely by successive selections describing a Technical context. Thus, in the case of spare parts (PR), you need to select in sequence:

• the technical domain (left-hand column)
• then the section (central column)
• and finally the subsection (on the right).

Les boutons de la ligne du bas ont les fonctions suivantes :

		To confirm the selection and access the information (in certain cases, the program will prompt you additional information).
		This button is active if the documentation in question has already been consulted and enables you to return to the last technical context consulted.
		Allows you to access help on the documentation currently being consulted.
		Closes the menu with no further action.
