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 pos-

sible 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

By limited 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

there line of sight is re-established again. 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 terminate the Navi-

gation Software, if it is not needed or satellite reception is not

possible for a longer period, for this reason. 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 situation.

Note

Please note, that your appliance is preset to not shut

down automatically after a few minutes without activ-

ity. 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.
