5 FC1: Operation for Legally Relevant Functionalities
5.3.3 Navigation via Touch Screen
General
There are two buttons at the lower edge of the touch screen. Depending on
the actual context, they are mostly labeled with following icons:
back and home
or
back and basic display
Touching a button labeled (home) or (basic display) invokes the
corresponding display. The basic display can always be reached in at most
two steps – either by touching the buttons and consecutively or by
touching
solely, when directly available.
The button labeled
(back) always leads you to the display that has been
invoked most recently.
If the buttons are labeled (OK) and (Cancel), a user action has been
carried out that requires confirmation, e.g. a calendar time adjustment. User
actions can be accepted by (OK) or discarded by (Cancel).
Navigation options in home display
Touching a folder in the home display opens it and shows the AFBs being
included.
Touching the icons of the AFBs or other selected functionalities invokes the
corresponding fiscal or main displays.
Navigation options in other displays
Most displays show measurement results, status information or settings.
An underlined text element always represents a hyperlink, e.g. a reference
to another display showing further details. Actions are also marked as
hyperlinks in the FC1 display.
