GPS Enabled
Your phone’s GPS Enabled feature uses information from Global Positioning
System (GPS) satellites orbiting the Earth to determine the approximate
geographical location of your phone, expressed as latitude and longitude. The
availability and accuracy of this location information (and the amount of time
that it takes to calculate it) will vary depending on the environment in which you
are using the GPS feature. For example, GPS location fixes are often difficult to
obtain indoors, in covered locations, between high buildings, or in other
situations where you have not established a clear broad view of the sky.SEE:
“IMPORTANT: Things to Keep in Mind”on page 116.
When you make a 911 emergency call, the phone’s GPS feature can help
emergency personnel locate 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 your phone’s display screen.
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.

IMPORTANT: Things to Keep in Mind
If you are using your phone’s GPS feature while driving, please give full
attentiontodrivingandtotheroad.
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
butarenotlimitedto:
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.

Making an Emergency Call
The satellites used by your phone’s GPS feature are controlled by the U.S.
government and are subject to changes implemented in accordance with the
Department of Defense GPS user policy and the Federal Radionavigation Plan.
These changes may affect the performance of your phone’sGPSfeature.
Making an Emergency Call
Dial 911 to be connected to an emergency response center. If you are on an
active call, you must end it before calling 911.
When you make an emergency 911 call, your phone’s GPS feature begins to
seek information to calculate your approximate location.It will take your
phone’s GPS feature some time to determine your approximate location.
Even where your phone has good access to sufficient GPS satellite signals and
network assist data, it may take 30 seconds or more to determine the
approximate location. This time will increase where there is reduced access to
satellite signals. When your approximate location is determined, it is made
available to the appropriate emergency response center.
In some cases, your local 911 emergency response center may not be
equipped to receive GPS location information.For this reason, and because
the GPS location information reported is only approximate or may not be
available in your location (see“IMPORTANT: Things to Keep in Mind”on
page 116),always report your location to the 911 operatoryou speak to when
making an emergency call, if able, just as you would when using a phone
without GPS capabilities.
NOTE: If you are concerned about whether your local 911 emergency
response center is equipped to receive GPS location
information, contact your local authorities.
In general, if your phone has access to signals from more GPS satellites, your
location will be determined faster and more accurately than if your phone has
access to signals from fewer GPS satellites.
If your phone does not have adequate access to GPS satellites signals, the
location of the nearest cell tower in contact with your phone is automatically
made available to emergency response center, if the center has the capability to
receive such information.
See“Enhancing GPS Performance”on page 120 for information on how to help
your phone determine your location.

Viewing Your Approximate Location
the number of satellites used to calculate the location. In general, more
satellites make for better accuracy.
To calculate your location again:
It may take your phone several minutes to complete the process of determining
your location. During this time, a message usually displays on your phone’s
screen saying your phone is scanning for satellites. For tips on getting the best
location calculation, see“Enhancing GPS Performance”on page 120.
ThePositionscreen displays the updated information.
To cancel a location calculation before it is completed:
Each time your phone’s approximate location is calculated, the latest location
information is stored in your phone and remains there even when your phone is
powered off. You will see this information the next time you view thePosition
screen.
If you received a phone call or alert while attempting to determine your phone’s
location, thePositionscreen will disappear, but your phone will continue
attempting to determine its location. If it is successful, the new location
information will be displayed the next time you view thePositionscreen. PressBunder RFRSH.
PressBunder CANCEL to return to thePositionscreen.

Enhancing GPS Performance
Sometimes your phone’s GPS feature may be unable to complete a location
calculation successfully. If this happens when you are making an emergency
call, the location of the nearest cell tower in contact with your phone is made
available to the appropriate emergency response center if the center has the
capability to receive such information. If this happens when you are trying to
view your location on your phone’s screen, you will see a message indicating
that your phone cannot access satellites.
To improve accuracy and increase your chances of a successful calculation, do
the following while your phone is determining your approximate location:
Sta y in th e o pe n .TheGPSfeatureworksbestwherethereisnothing
between your phone and a large amount of open sky. If possible, go
outside, away from tall buildings and foliage. While performance in a
building is improved by moving closer to windows, glass with certain sun
shielding films may block satellite signals.
Hold the phone to enhance reception.Signals from GPS satellites are
transmitted to your GPS antenna, which is inside the back of your phone,
opposite the earpiece, behind the Nextel label. Hold your phone away from
your body, giving the antenna clear access to satellite signals. Do not cover
the antenna area with your fingers or anything else.
Sta n d s til l.If possible, stand still until your phone is finished determining
your location. Moving the phone at a walking pace while the phone is
calculating your approximate location may substantially decrease GPS
performance.
