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
satellites 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 de-
termine 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 lim-
its 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 unneces-
sarily. Also terminate the Navigation Software, if it is not needed or satellite recep-
tion 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 navigation software is still active. Here, it can take a
short time for the position to be updated again, according to the reception situa-
tion.
Note
Please note, that your appliance is preset to not shut down automati-
cally 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 satel-
lites better (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
(see page 10).
