Java Applications and GPS
EnabledSome Java applications can make use of your
phone’s GPS feature to determine the approximate
geographical location of your phone. (See “GPS
Enabled” on page 88 for more information on the
GPS feature.) However, for privacy reasons, you
may not always want Java applications to access
the location of your phone. Your phone protects
your privacy by giving you the option to block all or
some Java applications from accessing the
location of your phone.
Setting Privacy for All Java
ApplicationsThese options control the privacy of all Java
applications on your phone:
 Restricted— No Java or similar software
applications may access the location of your
phone. However, location information may still
be available to the phone’s owner, fleet
manager, or account administrator.
 Unrestricted— All Java applications may
access the location of your phone, without
notifying you.
ByPermission— When a Java application
attempts to access the location of your phone,
you are prompted to give permission. However,
location information may still be available to the
phone’s owner, fleet manager, or account
administrator.
See “Setting Privacy Options” on page 94 for
information on choosing these options. 
						

							86Java ApplicationsGranting or Denying PermissionIf you chooseBy Permission, you must grant or
deny each Java application access to the location
of your phone when the application requests
access for the first time. You may be required to
grant or deny subsequent requests from the same
application, depending on the privacy setting you
choose for the individual Java application (see
“Setting Privacy for Each Java Application”).
When a Java application requests access to the
location of your phone, a screen appears informing
you.
To deny this request:
1PressAunderDeny. The application does not
access the location of your phone.
2Select the denying option you want:
 Always— If the application requests access
to the location of your phone again, the
request is denied without notifying you.
 For this session— If the application
requests access to the location of your phone
again before you power off your phone, the
request is denied without notifying you.
OnlyOnce— If the application requests
access to the location of your phone again,
you are prompted to grant or deny
permission.To grant this request:
1PressAunderGrant. The application accesses
your phone’s location.
2Selectthegrantingoptionyouwant:

							88GPS EnabledYour 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”.
When you make a 911 emergency call, the GPS
feature of your phone 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 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.
IMPORTANT: Things to Keep
in MindIf 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 
						

							89
Making an Emergency Call
 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 location. Advice
on how to improve GPS performance is
provided in “Enhancing GPS Performance” on
page 91.
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 locationinformation 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 your phone’s location
calculation: if such assistance information
becomes unavailable, it may reduce the speed and
accuracy of the location calculation.
The satellites used by the GPS feature of your
phone 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 the GPS
feature of your phone.
Making an Emergency CallDial 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, the GPS
feature of your phone begins to seek information to
calculate your approximate location.It will take
the GPS feature of your phone some time to
determine your approximate location.Even
where your phone has good access to sufficient 
						

							90GPS Enabled
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 88),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 the emergency
response center, if the center has the capability to
receive such information.
See “Enhancing GPS Performance” on page 91 for
information on how to help your phone determine
your location.
Viewing Your Approximate
Location1From the main menu, selectGPS > Position.
2Scroll to view the entire screen.
This displays the following information about the
last time your location was calculated:
The time (as Greenwich Mean Time) and date
that the location was last calculated
The approximate location, expressed as latitude
and longitude
The estimated accuracy of the calculated
location. This estimate of accuracy is only a very
rough estimate and may vary substantially from
the actual accuracy of the approximate location
information reported.

Enhancing GPS Performance
The number of satellites used to calculate the
location. In general, more satellites make for
better accuracy.
To calculate your location again:
PressAunderRfrsh.
It may take your phone several minutes to
complete the process of determining your location.
During this time, a message usually appears on
your phone’s display saying your phone is
scanning for satellites. For tips on getting the best
location calculation, see “Enhancing GPS
Performance”.
ThePositionscreen displays the updated
information.
To cancel a location calculation before it is
completed:
PressAunderCancelto return to thePosition
screen.-or-
Presseto return to the idle screen.
Each time approximate location of your phone 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
thenexttimeyouviewthePositionscreen.If you received a phone call or alert while
attempting to determine your location, thePosition
screen 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 thePosition
screen.
Enhancing GPS PerformanceSometimes the GPS feature of your phone 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 the phone’s display, you will
see a message indicating that your phone cannot
access satellites. 
						

							92GPS Enabled
To improve accuracy and increase your chances of
a successful calculation, do the following while
your phone is determining your approximate
location:
Stay in the open. The GPS feature works best
where there is nothing 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.
Extend your phone antenna.Hold your phone to enhance reception. Signals
from GPS satellites are transmitted to your GPS
antenna, which is in your phone antenna. Hold
your phone away from your body, giving the
antenna clear access to satellite signals. Do not
covertheantennaareawithyourfingersor
anything else.
