4.1.1  Initialising the GPS receiver 
Note: It can take up to 20 minutes to initialise the GPS receiver for the 
first time. 
Each time you switch on the receiver after this, the GPS reception will 
start within one minute. 
If the navigation device has been switched off for more than a week, the 
next initialisation can take up to 10 minutes. 
As soon as the navigation device has been switched on, initialisation of 
the GPS-receiver will begin. 
In the right-hand top corner of the display, you will see the 
GPS symbol. 
As soon as data from at least 3 satellites is received, the symbol 
changes to 
 GPS Ready. 
Note: If the 
GPS symbol displays GPS Ready after considerably less 
than 20 minutes, then it is best to switch off the receiver for at least 15 
minutes so as to guarantee reliable operation of the receiver. 
Caution! If you have connected the navigation device to the power 
supply using a cigarette lighter, remove the connector before you leave 
the vehicle standing for a long period of time. 
As the GPS receiver requires a constant power supply, it could run 
down the vehicle´s battery.
