WAN Communication
A contract with a communications provider is required in order to use the WAN communications
functions built into the Smart Device. The available WAN communications functions will be
determined by the contract between the customer and his or her communications provider.
Consult your communications provider for details of the network services.
GPS
When you use the Smart Device for the fi rst time or after an extended period of no use, it
may take a long time before the Smart Device determines its positioning. In such a case,
operate the GPS mode where there are no obstacles in the surroundings and wait for at least
15 minutes or longer.
The GPS module integrated in the Smart Device uses signals emitted by the satellites
operated by the government of the United Sates. The accuracy of positioning information
you obtain on the Smart Device may be affected by the condition of these satellites.
The GPS module may not be able to receive the signals in locations such as inside a building
or in a tunnel. If you are installing the device in your car, determine the installation location
after making sure that it can receive the signals.
