“Location”).
z
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 losses such as ones caused by using the
GPS for these purposes or by failing to confirm a positioning
result or to communicate due to handset failure, malfunction or
external factors such as power failure (including battery
exhaustion).
z
GPS is a service administered by the U.S. Department of
Defense. 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 may change
depending on the location of the GPS satellites.
z
Note that GPS uses the radio waves from artificial satellites,
therefore the following conditions may prevent the radio waves
from being received or prevent the reception status of the radio
waves from being satisfactory, resulting in an error of 300 m or
more for location information.
In or under a dense forest, in density area with buildings or
residence
In or under buildings
In a basement, tunnel, underground or underwater
Near high-tension line
Inside cars, trains, etc.
In bad weather with heavy rain/snow, etc.
In bags or boxes
When people or objects are blocking the handset
When hands are covering the GPS antenna area
z
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,
etc. in each country and the area.
z
Packet communication charges may be incurred, since assisted
GPS data such as satellite information is automatically retrieved
when you measure present location.
z
Packet communication charges are incurred when you display a
map based on location information, etc.
