Viewing Your Approximate Location
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 67), always report your location to
the 911 operator you 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 70 for
information on how to help your phone determine
your location.

Location
1 From the main menu, select GPS > Position.
2 Scroll 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.
