Each page of the System History displays a summary of five system histories. The latest
system history is displayed at the top of the screen while the oldest system history is
displayed at the bottom of the screen. The more pages you go down to, the older the system
histories become.
Pages are successively switched by touching the <←> or <→> button. You can touch the
page number and directly jump to a specific page.
If you touch the summary of a system history, the details of that system history are displayed
in a popup window. To make the popup window disappear, touch the screen again.
