Basic information about the
touch screen
The Traffic Assist is fitted with a touch
screen.
Operation
When you touch a button on the touch-
screen, the button in question is briefly
shown outlined in red to confirm the se-
lection.
If you touch a button that is not active at
the moment, a short signal tone sounds.
Calibration
If the touch screen starts responding im-
precisely and e.g. buttons have to
be touched off-centre in order to be actu-
ated, calibration should be undertaken.
The calibration function is started from
the Settings menu (see also page 48).
Basic information about the
menus
During operations, you are assisted by
various menus and entry windows.
Entries made with the entry
menu
Some applications require entries to be
made via the entry menu. The entry menu
is operated in a similar way to a keypad.
The character entered on the keypad is
displayed in the top line of the entry
menu. The central area is used to enter
characters. Help functions are provided in
the right line. Descriptions of how to op-
erate the menu are provided below.
Note:
To ensure that the display's surface is not
damaged, you may only touch it with
your fingers or a blunt, non-smearing ob-
ject.
