■
About the positioning function
･
The GPS is operated by the Department of
Defense of the United States. This suggests that
for reasons of U.S. defense, the conditions of radio
waves used for the GPS may get under control to
the extent that such radio waves will be degraded
or stopped.
･
Because the GPS uses radio waves from
satellites, the FOMA terminal may fail to receive
them or will hardly receive them under any of the
following conditions:
･
Inside or at the foot of a building
･
Under the ground, in a tunnel, in the ground or in
water
･
In a bag or box
･
On a street lined with large buildings or in a
residential area
･
In a wood or under a big tree
･
Nearby a high-voltage cable
･
In a car or train car
･
Bad weather such as heavy rain or snow
･
When there is someone or something that blocks
your mobile phone
･
When you hold your mobile phone so that your
hand covers its screen, keys, microphone or
speaker
If such a condition occurs, the location information
you get may have an error of 300 m or above.
･
GPS satellites are continuously rotating around
the Earth; therefore, even in the same
environment, the conditions of radio waves
received may vary from time to time, with the
result that the location information obtained may
include a significant error or the positioning
operation itself may fail.

DoCoMo will not be held responsible for any
economic loss resulting from any error,
malfunction, failure or any external factor such as
electric power failure (including battery shortage)
that leads to unavailability of checking the
positioning (communication) result.
･
Your FOMA terminal is unavailable as the
navigation equipment for airplanes, vehicles or
people. DoCoMo will not be held responsible for
any loss or damage resulting from navigation
based on the location information obtained.
･
Your FOMA terminal is unavailable as a high-
precision GPS for measurement. Therefore,
DoCoMo will not be held responsible for any
problem from any error in location information.
INFORMATION
●
If your FOMA terminal is outside the service area (or
overseas), Position Location is the only GPS function
available.
Checking your current location
Position Location
This GPS function allows you to determine your current
location, display a map, and start a GPS-compatible
i-
α
ppli application. This function also allows you to
send the determined location information by i-mode
Mail or add it to your phonebook.
･
Position Location may be available even if the user of
the FOMA terminal is outside the service area (or
overseas). Note, however, that the positioning may
take time or fail.
･
