Use the GPS system with great care. DOCOMO
is not liable for any damage caused by
abnormality of the system.
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
terminal or the power failure.
You cannot use the terminal as a navigation
device for an aircraft, vehicle, and person.
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 terminal as a high-
accuracy measurement GPS. Note that
DOCOMO shall have no liabilities whatsoever
even if you suffer damage or loss due to a
deviation of the location information.
The GPS signals cannot be easily received
near a vehicle's sun visor with metal parts.
GPS is operated by the U.S. Department of
Defense. The department controls the
accuracy of the system, and manages the
system. 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.
Some wireless communications products
(mobile phone, data detectors and some
others) block satellite signals and also causes
instability of signal reception.
Some map displays based on location
information (latitude/longitude information)
may be not accurate due to some countries'
or regions' regulations.
Where radio waves are difficult to
receive
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 bag or box
Inside or under a thick covering of trees
In a car, inside a train compartment
When there are obstructions (people or
objects) near the terminal
Inside a basement or tunnel, and below
the ground or water
In buildings-clustered or residential area
Near a high-voltage cable
Bad weather such as heavy rain or snow
