284. NavigatorYour device has an internal GPS receiver that receives low-power radio signals from satellites, and measures the traveltime of the signals. From the travel time, the GPS receivercan calculate its location to within a few meters. Thecoordinates are expressed in degrees and decimal degreesformat using WGS-84 coordinate system.The GPS receiver is located in the upper right corner of theslide cover. When using the receiver, hold the device uprightin your hand with an orientation toward the sky.Note that establishing a GPS connection may take severalminutes.As availability of GPS related services depends on wireless environment andsystems, the services may not fuction in all environments at all times.

Accuracy can also be affected by poor satellite geometry.Availability and quality of GPS signals may be affected by your location, buildings, naturalobstacles, and weather conditions. The GPS receiver should only be used outdoors to allowreception of GPS signals.Any GPS should only be used as a navigation aid. It should not be used for precise locationmeasurement and you should never rely solely on location data from the GPS or A-GPSreceiver for positioning or navigation.Almost all digital cartography is inaccurate and incomplete to some extent.
