Gps (Global Positioning System); External Gps Antenna - Medion Navigation Unit Operating Instructions Manual

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 (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 naviga-
tion.
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. However, you can also switch the device off by means of the On/Off
switch in the case of a shorter interruption to your journey. Pressing the same switch again
will activate a restart. The GPS receiver will also be reactivated at the same time, if naviga-
tion software is still active. Here, it can take a short time for the position to be updated
again, according to 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.

External GPS antenna

This second optional GPS antenna makes it possible to receive the signals of satellites bet-
ter (e. g. in the case of vehicles with a metallized windscreen).
1. The antenna should be pointing upwards.
2. Push the plug of the external GPS antenna into the opening provided for it.
