ArcSoft PDA Phone Manuel D’Utilisation

Using GPS  159

  Signal reception may be affected by obstructions such as high-rise 

buildings, tunnels, bridges, forests, weather (rainy or cloudy days), 
etc. If the vehicle’s visor contains metal, it will be difficult for the GPS 
signal to pass through. To have better signal reception, try connecting 
your device to an external GPS antenna.

  The Global Positioning System (GPS) is built and operated by the US 

Defense Department. The Department is responsible for the accuracy 
and maintenance of the system. Any changes that the Department 
makes may affect the accuracy and function of the GPS system.

  Wireless communication products (such as mobile phones or radar-

detecting devices) may interfere with the satellite signal, resulting in 
unstable signal reception.

  Please do not leave your Pocket PC in the vehicle and expose to direct 

sunlight to avoid overheating the battery that could pose damage to 
the device or risk to the vehicle.

Before you start to use your device for GPS navigation, open the QuickGPS 
program first to download Ephemeris data (current satellite position and 
timing information) onto your device. This data is needed to determine the 
GPS position of your current location.
QuickGPS downloads Ephemeris data from a Web server, instead of from 
the satellites, using the Internet connection on your device, which can 
be via ActiveSync, Wi-Fi, or GPRS. This significantly speeds up the time for 
determining your GPS position.
