• Some radios, entertainment equipment and
other electronic devices may generate
signals that can block or interfere with the
GPS receiver ability to receive the distant
satellite signals, particularly when such
devices are operating in close proximity to
the GPS receiver. Therefore, in a 911 call, or
when otherwise using the GPS location
function, always move your phone away
from any such devices.

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 151.

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 your phone’s location
calculation: if such assistance information
becomes unavailable, it may reduce the speed and
accuracy of the location calculation.
