GPS (Global Positioning System)
GPS is a satellite-backed system for determining your position. With the help of 24 satel-
lites revolving around the earth, it is possible to determine your position on earth with the
accuracy of a few meters. The satellite signals are received by the antenna of the built-in
GPS receiver, which must have a "line of sight" to at least 4 of these.
Note
When the line of sight is interrupted (e.g. in tunnels, between houses, in
woods or also in vehicles with metal-coated windows) it is not possible to
determine the position. The satellite reception however automatically picks
up again as soon as the obstacle has been passed and the line of sight is re-
established. Moving slowly (e.g. slow walking) also limits the accuracy of
the navigation.
The GPS receiver consumes additional power. This is especially of concern when running
on batteries. To conserve power do not turn on the GPS receiver unnecessarily. Also ter-
minate the navigation software if it is not needed or satellite reception is not possible for a
longer period. You can also switch the device off by means of the On/Off switch if you
experience a short interruption in your journey, pressing the same switch again will reacti-
vate a restart. The GPS receiver will also be reactivated at the same time, if the navigation
software is still active. There may be a delay for the position to be updated again, this is
dependent on the reception situation.
Note
Please note that your appliance is preset to not shut down automatically
after a few minutes without activity. You can change this preset in the
Settings mode. If the GPS receiver has not been active for some hours, it
must orientate itself again. This process may take a while.
