GSM Communication

To use the GSM functions, you must receive service from a wireless service provider.

Available GSM 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 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.

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 integrated in the Handheld Terminal receives signal from satellites,

and it 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.
