To start, choose "search" from the main menu. Enter one criterion or more and choose "search". If the search returns no results, your search is too specific: remove one criterion.
In the result page, choose one element: you can now see the details. The "call" command directly dials the number to book what you selected.
Use back command to the previous screen. Once on the main menu, you can use "list" to get your previous search results and "latest" to go to the latest selected element in the result.
