GENERAL OPERATION
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 (model dependent)
A calibration can only be carried out on
devices with resistive display, devices
with capacitive display do not have to be
calibrated.
If the touch screen responds
inaccurately, a calibration must be
carried out.
The calibration function is started from
the
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.
4 hours.
If the device cannot be switched off
anymore or no longer works reliably, it
is possible to switch off the device
completely by pressing the button on
the top for longer than 7 seconds.
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.
