The access point forA-GPS can be defined in positioning settings. A wirelessLAN (WLAN) access point cannot be used for this service.Only a packet data internet access point can be used. Yourdevice asks you to select the internet access point whenGPS is used for the first time.Tips on creating a GPSconnectionCheck the satellite signal status — Select Menu >Applications and GPS data > Options > Satellitestatus.If your device hasfound satellites, abar for each satelliteis shown in thesatellite informationview. The longer thebar, the stronger thesatellite signal.When your device has received enough data from thesatellite signal to calculate your location, the colour of thebar changes.Initially your device must receive signals from at least foursatellites to be able to calculate your location. When theinitial calculation has been made, it may be possible tocontinue calculating your location with three satellites.However, the accuracy is generally better when moresatellites are found.If no satellite signal can be found, consider the following:• If you are indoors, go outdoors to receive a bettersignal.• If you are outdoors, move to a more open space.• If the weather conditions are bad, the signal strengthmay be affected.• Some vehicles have tinted (athermic) windows, whichmay block the satellite signals.• Ensure you do not cover the antenna with your hand.Establishing a GPS connection in the car, in badweather conditions, or in a challenginggeographical environment may take a longtime.The GPS receiver draws its power from thedevice battery. Using GPS may drain thebattery faster.MapsThe GPS of this device is not for professional positioning.GPS connection time might also be affected by weather,use environment, and other condition of use. GPS shouldonly be used as a navigation aid and should not be usedfor emergency or task which requires more precisepositioning. 55 Travelling
