Precautions on the Use of
GPS Functions
You may need i-mode subscription for the use of the
GPS function.
GPS is operated by the U.S. Depar tment of
Defense. Therefore, GPS radio wave condition may
be controlled (degradation of accuracy, suspension
of radio wave transmission, etc.) at the discretion of
the U.S. Department of Defense.
Note that radio waves may not be received or it may
be difficult to receive radio waves in the following
conditions, since GPS uses radio waves from a
satellite.
Inside or immediately under a building
Inside a basement or tunnel, and below the
ground or water
Inside a bag or box
High-rise building district or densely populated
residential area
Inside or under a thick covering of trees
Near a high-voltage cable
In a car, inside a train compartment
Bad weather such as heavy rain or snow
When there are obstructions (people or objects)
near a mobile phone
When you are covering the display or earpiece of
your mobile phone with your hand.
The obtained location information may deviate by
300 m or more under the above conditions.
When the FOMA terminal is outside of the service
area (or it is overseas), the GPS function is not
available.
There are about 24 GPS satellites in orbit at an
altitude of about 20,000 km, and each satellite takes
about 12 hours to travel around the earth. Therefore,
radio wave reception condition may vary depending
on the date/time even if the operating environment is
the same. For example, a significant deviation could
occur to the location information or it may not be
possible to identify a location.
Please note that DoCoMo shall have no liabilities
for any purely economic loss including those due
to missing a chance to check the measurement
(communication) results because of external factors
(including the running out of the battery), such as
a failure, malfunction, or any other problems of the
FOMA terminal or the power failure.
You cannot use the FOMA terminal as a navigation
device for an aircraft, vehicle, and person.
Please note that DoCoMo shall have no liabilities
whatsoever even if you suffer damage or loss
while performing a navigation using the location
information.
You cannot use the FOMA terminal as a high-
accuracy measurement GPS. Please note that
DoCoMo shall have no liabilities whatsoever even if
you suffer damage or loss due to a deviation of the
location information.

Checking Your Location
You can measure your current location to
determine where you are. You can display a
map based on the location information you
obtain, mail the location information, or save
the location information in the Phonebook.
No communication charge is required for confirming
your current location. Note, however, that there is an
extra packet communication charge for displaying a
map based on your current location information.
