Operating the phone in hidden mode
is a safer way to avoid malicious
software.
Do not accept Bluetooth
connectivity from sources you do not
trust.
Another alternative - switch off the
Bluetooth functionality. This will
not affect other functionalities of
the phone.
Infrared
You can set up the phone to send
and receive data through its infrared
(IR) port. To use an IR connection,
the device with which you want to
establish a connection must be IrDA
compliant. You can send or receive
data to or from a compatible phone
or data device (for example, a
computer) through the IR port of
your phone.
Do not point the IR (infrared) beam
at anyone's eye or allow it to
interfere with other IR devices. This
device is a Class 1 laser product.
When sending or receiving data,
ensure that the IR ports of the
sending and receiving devices are
pointing at each other and that
there are no obstructions between
the devices.
To activate the IR port of your phone,
select Menu > Settings >
Connectivity > Infrared.
To deactivate the IR connection,
select Menu > Settings >
Connectivity > Infrared. When the
phone displays Deactivate infrared?,
select Yes.
If data transfer is not started within
2 minutes after the activation of the
IR port, the connection is canceled
and must be started again.
IR connection indicator
When is shown continuously,
the IR connection is activated, and
your phone is ready to send or
receive data through its IR port.
When blinks, your phone is
trying to connect to the other
device, or a connection has been
lost.
Packet data
General packet radio service (GPRS)
is a network service that allows
mobile phones to send and receive
data over an Internet protocol
(IP)-based network. GPRS is a data
bearer that enables wireless access
to data networks such as the
Internet.
Enhanced GPRS (EGPRS) is similar to
GPRS but enables faster
connections. For more information
