Applications
GPS is a function to retrieve location information
of the handset by receiving radio wave from GPS
satellites. Enable location information services
([Use wireless networks] or [Use GPS satellites])
to measure the present location (
n
P. 86).
You cannot use the handset as a navigation
system for professional use of aircrafts, vehicles,
person, etc. or surveying GPS of high accuracy.
Note that DOCOMO shall not be liable for the
pure economic loss caused by using the GPS for
these purposes or other purposes such as you
cannot confirm the positioning (communication)
result due to handset failure, malfunction or
external factors such as power failure (including
battery exhaustion).
GPS is a service administered by Department of
Defense of USA. Therefore, GPS radio wave
condition may be controlled (accuracy
degradation, radio wave abort, etc.) for US
national security reasons. In addition, the same
results may not be retrieved even when
positioned in the same location and environment,
since the radio wave conditions change
depending on the location of the GPS satellites.
Note that GPS uses the radio waves from
satellites, therefore the following conditions may
cause the radio waves to abort or have difficulty
to receive resulting in an error of 300 m or more
for location information.
In or under densely trees, in density area with
buildings or residence
In or under buildings
In a basement, tunnel, underground or
underwater
Near high-tension line
Inside cars or trains

When using a GPS function overseas, the
displayed map based on the acquired location
information (latitude and longitude information)
may not be accurate because of the legal system
in each country and the area.
Packet communication charges may be incurred,
since assist data such as satellite information is
automatically retrieved when you position
present location.
Packet communication charges are incurred
