>>> GENERAL OPERATION
For devices without the I/O switch on the
underside:
> Press the switch on the top of the
navigation device for longer than
3 seconds to finally switch it off.
Basic information about the
touch screen
The Navigation device 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
selection.
If you touch a button that is not active at
the moment, a short signal tone sounds.
Calibration
If the touch screen starts responding
imprecisely, calibration should be
undertaken.
The calibration function is started from
the menu (see also page 137).
Note:
We recommend that you place the
Navigation device in sleep mode in the
event of short interruptions to operation
(of up to a week).
This significantly reduces the switch-on
time and the Navigation device finds the
satellites required for navigation much
faster.
If route guidance was active when sleep
mode is activated, it is automatically
resumed if the Navigation device is
switched back on again within approx.
4hours.
If the device cannot be switched off
anymore or no longer works reliably, it
is possible to switch off devices without
I/O switches completely by pressing the
button on the top for longer than
7seconds.
Note:
To ensure that the display's surface is
not damaged, you may only touch it with
your fingers or a blunt, non-smearing
object.
