Confirm the installation. The .JAR file is required for
installation. If it is missing, the smartphone may ask
you to download it. If there is no access point defined,
you will be asked to select one. When you are
downloading the .JAR file, you may need to enter a
user name and password to access the server. You can
obtain these from the supplier or manufacturer of the
application. The smartphone informs you when
installation is complete.
Tip: When you are browsing, you can download an
installation file and install it immediately. Note,
however, that the connection is left running in the
background during installation.

Data transmission

This device employs the data transmission capabilities of
the GSM network to send multimedia messages, short
messages and e-mail, and to establish connections with
remote computers.
Wireless data connections can be made from most
locations where your smartphone operates. However, it is
recommended that you move the device to a location
where the strongest possible wireless signal can be
obtained. When the signal is strong, data transmission is
efficient. In general, you should not expect the same
performance from wireless data communications as from
landline communications, due to the inherent
characteristics of the wireless environment.

The following factors may impair wireless connections in
the form of noise, low or lost signal, erroneous function of
the device, or distorted display:
Noise - Radio interference from electronic appliances and
equipment, as well as from other phones will affect the
quality of wireless data transmission.
Roaming - As the smartphone user moves from one
network cell to another, the signal strength of the channel
drops and the wireless telephone exchange may hand the
user over to a different cell and frequency, where the
signal is stronger. A cell handover may also occur when
the user is stationary, due to varying network traffic loads.
Such handovers may cause slight delays in transmission.
Electrostatic discharge - A discharge of static electricity
from a finger or a conductor may cause erroneous
functions in electrical devices. The discharge may result in
distorted display and unstable software operation.
Wireless connections may become unreliable, data may
become corrupted, and transmission halted. In this case
you need to end the existing call (if any), switch off the
device (if on) and remove the battery. Then replace the
battery and establish a new wireless connection.
