GSM/W-CDMA Communication
To use the GSM/W-CDMA functions, you must receive service from a wireless service
provider. Available GSM/W-CDMA functions may be dependent on the service provider
to which you connect. Please consult your service provider for details about network
service.
If you use GSM/W-CDMA and WLAN at the same time, the communication speed of
WLAN may be reduced, or the reception of WLAN signals may be disconnected, due to
the operational state of GSM/W-CDMA.
GPS
When you use the Handheld Terminal for the fi rst time or after an extended period of no
use, it may take a long time before the Handheld Terminal 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 Handheld Terminal uses signals emitted by the
satellites operated by the government of the United Sates. The accuracy of positioning
information you obtain on the Handheld Terminal 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.
