IMPORTANT: Things to Keep in Mind

If you are using your phone’s GPS feature while driving, please give full attention to driving and to the road.

Where adequate signals from multiple satellites are not available (usually because your GPS antenna cannot establish a view of a wide area of open sky), the GPS feature of your phone WILL NOT WORK. Such situations include but are not limited to:

•In underground locations.

•Inside of buildings, trains, or other covered vehicles.

•Under any other metal or concrete roof or structure.

•Between tall buildings or under dense tree-cover.

•Near a powerful radio or television tower.

•When your GPS antenna is covered (for example, by your hand or other object) or facing the ground.

•Temperature extremes outside the operating limits of the phone.

Walking or driving very slowly may also substantially reduce GPS performance.

Even where location information can be calculated in such situations, it may take much longer to do so, and your location estimate may not be as accurate. Therefore, in any 911 call, always report the location to the emergency response center if you can and if you cannot, remain on the phone for as long as the emergency response center instructs you.

Even where adequate signals from multiple satellites are available, your GPS feature will only provide an approximate location, often within 150 feet (45 meters) but sometimes much further from your actual location. Advice on how to improve GPS performance is provided in “Enhancing GPS Performance” on page 120.

While the GPS feature of your phone can be a valuable navigational aid, it does not replace the need for careful navigating and good judgment. Never rely solely on one device for navigation. Remember that the accuracy of the location information and the time needed to obtain it will vary depending on circumstances, particularly the ability to receive signals from adequate numbers of satellites.

On emergency calls, your phone uses assistance information from the phone network to improve the speed and accuracy of the phone’s location calculation: if such assistance information becomes unavailable, it may reduce the speed and accuracy of the location calculation.
