you if your phone has adequate access to GPS satellite
signals and your emergency response center is
equipped to process such information.
You can also use the GPS feature to view your
approximate location. Location information appears on
the phone’s display.
Java applications loaded on your phone can also
request your location. If your phone is connected to a
laptop computer or similar device, software running on
that device can request your location. To protect your
privacy, you can control whether these requests are
granted. See “GPS Privacy Options” on page 88.
IMPORTANT: Things to Keep in Mind
If you are using the GPS feature of your phone 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.
In temperature extremes outside the operating limits
of your 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 your 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 locat ion.
